The term “Big Data” along with other trending topics such as “Data Analytics” and “Artificial Intelligence (AI)” have become buzzwords in the accounting profession in recent years. The skills of accounting professionals have evolved as technology has made rapid advances from using pencil and paper to typewriters and calculators, and eventually spreadsheets and accounting software. Data analytics in accounting is a relatively new skill set that is growing significantly in all areas of the accounting profession. Accounting professionals who can discern patterns and trends in big data and translate them into compelling strategic narratives will find themselves at the centre of the twenty-first-century business world. Therefore, accounting professionals can capitalise on numerous opportunities in this rapidly evolving, disruptive, but ultimately advantageous environment by embracing big data, data analytics, and artificial intelligence (AI) to stay ahead of the competition. Keywords: Artificial Intelligence (AI); Big data, Blockchain; Data analytics; Machine learning 2 The business environment is increasingly competitive, and most organizations are looking for an “edge”. For many companies, that “edge” is the implementation of new technology, enabling the mining of vast amounts of data (Big Data) using leading-edge analytical tools. –– Institute of Management Accountants [IMA] (2019) 1. Introduction Robotisation is rapidly influencing the way how humans interact, how work gets done, and identifying tasks that can be automated (Chartered Institute of Management Accountants [CIMA], 2022). With the advent of big data, data analytics, and artificial intelligence (AI), accounting and finance professionals can take advantage of several opportunities in this rapidly evolving, disruptive, but advantageous environment (Chartered Institute of Management Accountants [CIMA], 2022). The total amount of data created, captured, reproduced, and consumed worldwide is projected to grow rapidly, reaching 64.2 zettabytes or 64.2 trillion gigabytes in 2020 (See, 2021). Additionally, global data generation is expected to exceed 180 zettabytes over the next five years, reaching a peak in 2025 (See, 2021). This data can be captured and analysed to provide valuable insights that can support future business growth. Consequently, businesses need to employ tools that can help them in converting data into usable information, which requires the use of data analytics tools. Data analytics is the process of identifying patterns and trends in past raw data (often referred to as big data) to predict future events that assist in strategic decision-making while artificial intelligence (AI) entails data processing, making assumptions, and attempting to make predictions that are beyond human capabilities. Although the term “Big Data” is relatively new to the business world, it is already routinely used for practically every facet of human activity (Vasarhelyi, Kogan, & Tuttle, 2015). The fundamental reason for big data’s popularity is that recent advances in information technology, especially the Internet, have made available an exponentially growing amount of information (Vasarhelyi et al., 2015). More specifically, big data is widely recognised as the 3 next frontier for innovation, competition, and efficiency (Manyika et al., 2011). In line with this notion, the McKinsey Global Institute (2012) conducted a survey and found that 51% of the global business leaders believe that big data and data analytics are top priorities in their current business function. Furthermore, the Chartered Global Management Accountant [CGMA] (2013) surveyed more than 2000 Chief Financial Officers [CFOs] and finance professionals around the world and concluded that big data would revolutionise the way businesses operate over the next decade. Accounting professionals have an important role to play in big data and data analytics since accounting deals with the recording, information processing, measurement, analysis, and reporting of financial information (Liu & Vasarhelyi, 2014). Accounting practitioners around the world have emphasised the value of big data in the accounting and finance fields. For example, the Association of Chartered Certified Accountants [ACCA] and the Institute of Management Accountants [IMA] (2013a) contend that big data, cloud, mobile, and social platforms are changing the landscape for accounting and finance professionals, and they must adapt to the challenges posed by cybercrime, digital service delivery, and artificial intelligence. Similarly, the Chartered Global Management Accountant [CGMA] (2013) stresses the significance of big data, arguing that it raises significant challenges for the future role of accounting and finance. Accountants, who specialise in providing financial accounts to report on past performance, may be sidelined if they do not embrace this change and appreciate the new technologies (Chartered Institute of Management Accountants [CIMA], 2022). Alternatively, they might grasp the opportunity to become big data champions as a source of evidence to support decision-making and help reinvent the way businesses are done (Chartered Global Management Accountant [CGMA], 2013). With rapid advances being made in technology, accounting skills have shifted from using pencil and paper to typewriters, calculators, and eventually spreadsheets and accounting 4 software (Poddar, 2021). Data analytics in accounting is a relatively new skill set that is growing significantly in all areas of accounting. The value of the benefits of data analytics in accounting and finance has grown over time, and has in fact transformed the task processes, particularly those that provide inferences, predictions, estimations, and assurance to decisionmakers and information users (Austin, Carpenter, Christ, & Nielson, 2021). Consequently, accounting scholars, researchers, and practitioners worldwide view data analytics as a valuable tool for gaining new insights into businesses financials, identifying areas for process improvement, and reducing risk. Nowadays, accounting professionals globally provide significant support to their senior executives by analysing and interpreting the large volume of accounting data, most of which comes from non-traditional accounting systems (Siegel, 2013; Haverson, 2014; Davenport & Harris, 2017). Web server logs, Internet, and mobile phone clickstream recordings, social media, and a large number of machine-generated and sensor-detected systems are implemented to extract financial and non-financial information that is used to analyse and interpret the data to make important business decisions (Bertolucci, 2013; Löffler & Tschiesner, 2013). Added to this, several governments around the world have taken the initiative to improve third-party access to both internal government data and data collected from citizens and businesses as a key measure of administrative procedures, which will create more prospects for data analytics (Casselman, 2015; Office of Management and Budget, 2015). Furthermore, the use of artificial intelligence (AI) technologies (e.g., computer visions, natural language processing, speech recognition and machine learning) enables companies to improve their efficiency and obtain valuable insights about their customers and employees to develop more competitive customer and personnel strategies (Ernst & Young, 2020). Accounting professionals are playing a more strategic role in the field of artificial intelligence (AI) technology. Since the advent of big data, data analytics, and artificial intelligence (AI), 5 accounting professionals have demonstrated their ability in delivering greater value to businesses by generating higher revenues and streamlining processes. The remainder of the chapter is organised as follows. Section 2 discusses big data in accounting. Section 3 describes the data analytics in accounting including the role of data analytics in financial accounting, auditing, and management accounting, followed by Section 4 which provides an overview of artificial intelligence (AI) in accounting. The final section (Section 5) concludes the chapter. 2. Big Data in Accounting The term “Big Data” is defined as a huge dimension of unstructured and structured data derived from multiple sources (Ernst & Young, 2014). Structured data refers to the highly organised information stored in the relational databases of spreadsheets. In contrast, unstructured data refers to data from sources that are not highly organised (e.g., photos, videos, blogs, presentations, social media posts, satellite imagery, open-ended survey responses, and website content) that generally produce 85% of the world’s information today (Mills et al., 2012). The other data type is semi-structured data that contains both structured (highly organised) and unstructured (not highly organised) elements (e.g., emails, zipped files etc.). The term “Big Data” has become a buzzword in the accounting profession in recent years like other trending topics such as blockchain, artificial intelligence (AI), and machine learning (Boomer, 2018). Although there is no internationally accepted definition of big data, Gartner (2012) defines big data as “high-volume, high-velocity, and/or high-variety information assets that demand cost-effective, innovative forms of information processing that enable enhanced insight, decision making, and process optimization”. Big data is thus characterised by these “three Vs”, namely volume, velocity, and variety (Association of Chartered Certified Accountants [ACCA] and Institute of Management Accountants [IMA], 2013b). Volume indicates the massive size of datasets (e.g., Facebook, Google, Yahoo, blogs, 6 census records, etc.), velocity indicates the speed at that the data is generated (e.g., stock prices data that are generated very rapidly), while variety is the collection of data from different sources (both structured and unstructured) (Cao, Chychyla, & Stewart, 2015). Figure 1 shows the “3V” model of big data. Figure 1: The “3V” model of big data [Source: Merritt-Holmes (2016)] There are two other sources of big data, and these are veracity and value. Veracity indicates the accuracy and reliability of the data, while value focuses on the costs and benefits of data collection (Zhang, Yang, & Appelbaum, 2015; Merritt-Holmes, 2016; Janvrin & Watson, 2017). Furthermore, according to Zhang et al. (2015), big data includes four different elements, namely high volume, high velocity, high variety, and high veracity. The application of continuous auditing now largely depends on automated real-time data analysis due to the large volume and high velocity of data (Vasarhelyi, Alles, & Williams, 2010). However, high volume and high velocity create gaps between modern audit analytics and the demand for big data analytics. The huge variety and high veracity also generate new challenges because the current method of auditing has only limited competencies to deal with big data. 7 Although big data encompasses massive veracity, huge volume, and computing supremacy for the collection and processing of information, it cannot be stored, processed, and analysed using old-fashioned methods (Gartner, 2012). Big data cannot be used by businesses without a systematic analysis being undertaken. However, after efficiently scrutinising, cleaning, transforming, and properly interpreting the big data, it generates valuable insights (Cao et al., 2015). Furthermore, efficient analysis and appropriate interpretation of this data will speed up the revenue generation process, understand customers’ expectations and provide essential information to interested and relevant users (Trkman, McCormack, De Oliveira, & Ladeira, 2010; Davenport & Harris, 2017). When it comes to accounting, the purpose of big data is to collect, organise, and use data from a range of sources to gain new business insights in real-time. For example, accounting and financial analysts can access real-time data from anywhere with a network connection instead of relying on monthly financial reports.2 Although big data has several implications for business, particularly in terms of accounting software, making financial decisions, analysis of customer consumption patterns, and banking (Davenport & Harris, 2017), the importance of big data varies from organisation to organisation. For example, big data from the Big 4 accounting firms is not considered big for a small accounting and tax consultancy firm (Vasarhelyi et al., 2015). Likewise, the big data originating from the Big 4 firms is unlikely to be considered that big compared to NASA (Vasarhelyi et al., 2015). Whether a given amount of data is big or not depends on whether that data exceeds the capabilities of information systems that work with that data. Thus, storage and processing are considered to be the two measures of big data competencies (Vasarhelyi et al., 2015). 2 https://online.maryville.edu/blog/data-analytics-in-accounting/ (accessed on 8 March 2022). 8 Despite the fact that big data has become an emerging buzzword for accounting professionals in recent years, the impetus of accounting has always been to provide useful information to interested users (Capriotti, 2014). Although the main goal of accounting professionals is to provide information from a large volume of business records for decisionmakers to consider, accounting information originates from diverse sources such as paperbased systems, legacy-based systems, and highly technical business systems (Janvrin & Watson, 2017). Through the implementation of various software and analytical tools, accounting professionals identify, record, summarise, analyse, and report financial information for their internal and external users. Both internal and external auditors implement a variety of automated techniques (e.g., generalised auditing software) to review accounting information to ensure that managers prepare financial statements in accordance with relevant accounting standards and applicable laws. In this way, big data has changed the practice of measuring business transactions and ensuring their relevance. Additionally, big data offers companies the ability to capture transactions before their formal accounting entry, identify inventory movements before their actual receipt or delivery, identify customer calls before actual service activities are performed, and many more forms of identifying economic activities (Vasarhelyi et al., 2015). The measurement system for accounting transactions has been drastically changed due to new technology-driven changes and the advent of Enterprise Resource Planning [ERP] systems that speed up the process of capturing data and improving the data processing systems (Romero, Gal, Mock, & Vasarhelyi, 2012). Although no changes are visible in accounting practices and standards such as International Accounting Standards (IAS) and International Financial Reporting Standards (IFRS), big data is the main cause of a paradigm shift that makes it possible to identify and address business functions earlier (Vasarhelyi et al., 2015). Table 1 provides a list of several opportunities and challenges in implementing big data for 9 the accounting and finance profession as identified by the Association of Chartered Certified Accountants [ACCA] and the Institute of Management Accountants [IMA] (2013b). Table 1: Opportunities and challenges of big data for the accounting and finance profession Area Valuation of data assets Use of big data in decision making Use of Big data in the management of risk Opportunity Helping companies value their data assets through the development of robust valuation methodologies. Increasing the value of data through stewardship and quality control. Using Big data to offer more specialized decision-making support in real time. Working in partnership with other departments to calculate the points at which big data can most usefully be shared with internal and external stakeholders. Expanding the data resources used in risk forecasting to see the bigger picture. Identifying risks in real-time for fraud detection and forensic accounting. Using predictive analytics to test the risk of longer-term investment opportunities in new markets and products. Challenge Big data can quickly ‘decay’ in value as new data becomes available. The value of data varies according to its use. Uncertainty about future developments in regulation, global governance, and privacy rights and what they might mean for data value. Self-service and automation could erode the need for standard internal reporting. Cultural barriers might obstruct data sharing between silos and across organizational boundaries. Ensuring that correlation is not confused with causation when using diverse data sources and big data analytics to identify risks. Predictive analytic techniques will mean changes to budgeting and return on investment calculations.

Data Analytics in Accounting Data analytics can be defined as “processes by which insights are extracted from operational, financial, and other forms of electronic data internal or external to the organization” (KPMG, 2016). There are a variety of ways in which these insights can be derived, including historical, real-time, or predictive. They can be risk-focused (e.g., control effectiveness, fraud, waste, abuse, non-compliance with policy/regulatory) or performancefocused (e.g., increased sales, decreased costs, improved profitability, etc.) and frequently provide “how?” and “why?” answers to the initial “what?” queries commonly found in the information retrieved from the data (KPMG, 2016). Three distinct characteristics of data analytics are the data itself; the analytics applied to it, and the presentation of results in a way 10 that enables commercial value to be generated (Gantz & Reinsel, 2012). More generally, data analytics encompasses not only the collecting and managing of data but also visualising and presenting of data using tools, infrastructure, and methods to gain insights from big data (Mikalef, Pateli, Batenburg, & Wetering, 2015). Therefore, data analytics is a systematic process of investigating structured and unstructured data through various techniques such as statistical and quantitative analysis, as well as explanatory and extrapolative models to generate useful information for accounting decision-makers. Accounting has evolved in tandem with changing technology, from the use of pencil and paper to typewriters, calculators, spreadsheets, and accounting software (Poddar, 2021). Most accountants have the ability to analyse data as they are experienced in recording and analysing transactions. As well, they are well trained to document the accounting information, are familiar with financial statements, and have sufficient experience in various aspects of business decisions, making them experienced trusted advisors to businesses (Haverson, 2014). Therefore, technical skills, analytical thinking, and problem-solving competence have long been a part of the accounting profession. However, accounting data analytics is a relatively new skill set that is spreading rapidly in the accounting profession. The importance of data analytics has increased over time as accounting professionals implement the data analytics tools to infer, predict, and assure the business data to make a useful decision. For example, corporate executives and senior-level management are adopting data analytics to identify and infer operational inefficiencies (Dai, Byrnes, Liu, & Vasarhelyi, 2019). In addition, data analytics is an important area of investment for public accounting firms, particularly in consulting, tax advisors and auditing services (Earley, 2015). Tax professionals use data analytics to detect tax fraud and forecast future tax liabilities (DaBruzzo, Dannenfelser, & DeRocco, 2013). In addition, data analytics is now widely implemented by auditors to identify uncertain, ambiguous, or possibly fraudulent transactions 11 (Vasarhelyi, 2013; Verver & Grimm, 2013; Brown-Liburd, Issa, & Lombardi, 2015), and to understand and assess the safety and control of a client’s huge volume of datasets (Ernst & Young, 2014; Vasarhelyi et al., 2015). Apart from the demand for data analytics by accounting professionals, accounting scholars are considering data analytics in their accounting curricula. The Association to Advance Collegiate Schools of Business [AACSB]’s demand for data analytics as a component of an accounting degree demonstrates the relevance of data analytics given that graduates must possess abilities in creating, distributing, assessing, and interpreting data (Schneider, Dai, Janvrin, Ajayi, & Raschke, 2015). Additionally, the Pathways Commission on Accounting Higher Education (Behn et al., 2012), funded by the American Accounting Association (AAA) and the American Institute of Certified Public Accountants (AICPA), inspires the AACSB to introduce a new accounting program accreditation standards. These include accounting students’ learning experiences including “data creation, data sharing, data analytics, data mining, data reporting, and storage within and across organizations” (Association to Advance Collegiate Schools of Business International [AACSB], 2013). Furthermore, businesses implement data analytics tools in their day-to-day functions to increase their profits and reduce costs/overheads in various ways outside of accounting. For example, customer analytics is used in marketing to find and understand consumer purchasing habits and other behavioural patterns so that market trends can be predicted and forecast new opportunities. Algorithmic trading is used to speed up the current stock price monitoring systems. Although unstructured data is not used in business for analysis, the integration of data analytics accelerates the process of using unstructured data to boost the timeliness of business processes.3 3 https://online.maryville.edu/blog/data-analytics-in-accounting/ (accessed on 8 March 2022). 12 3.1 Types of Data Analytics There are four types of data analytics: descriptive analytics, diagnostic analytics, predictive analytics, and prescriptive analytics. They are summarised in the table below. Table 2: Types of data analytics Types of analytics Descriptive analytics Explanations Examples Provides insight based on past information. What is happening? Diagnostic analytics Examines the cause of past results. Why did it happen? Predictive analytics Assists in understanding the future and provides foresight by identifying patterns in historical data. What will happen? When and why? Assists in identifying the best option to choose to achieve the desired outcome through optimization techniques and machine learning. What should we do? Used in standard report generation and in basic spreadsheet functions such as counts, sums, averages and percent changes and in vertical and horizontal analyses of financial statements. Used in variance analyses and interactive dashboards to examine the causes of past outcomes. Can be used to predict an accounts receivable balance and collection period for each customer and to develop models with indicators that prevent control failures. Used in identifying actions to reduce the collection period of accounts receivable and to optimise the use of payable discounts. Prescriptive analytics Source: Tschakert, Kokina, Kozlowski, and Vasarhelyi (2016) Data analytics is often misinterpreted as just descriptive analysis (“what is”). However, what is really valuable is predictive (“what is going to happen”) and prescriptive analysis (“what should we do?”) rather than descriptive analysis (Tschakert et al., 2016). Companies and industries rely heavily on data analytics to take competitive advantage of technological innovations. Thus, regulators, external capital providers, and capital market participants consider the availability of data and their efficient analysis (Tschakert et al., 2016). Descriptive analytics focuses on what happened in the past. The term “Past” refers to any point in time when an event occurred, which could be a month ago or only a minute ago. Today, 90% of companies employ descriptive analytics, the most fundamental type of analytics. This sort of analytics examines both real-time and historical data to provide insights into the future rather than establishing a cause-and-effect relationship between events 13 (Tschakert et al., 2016). Google Analytics is a prominent example of descriptive analytics in action; it provides a concise overview of website activity, such as the number of visits in a certain period or the source of the visitors. Other business applications of descriptive analytics include sales revenue results coupled with purchase, cost per customer, customer credit risk, inventory measurement and accessibility, Key Performance Indicators (KPIs) dashboard, and monthly revenue report (Tschakert et al., 2016). Diagnostic analytics aims to further explore the cause of an event. The diagnostic analysis delves into descriptive analytics data to ascertain the underlying reasons of outcomes. For instance, if the descriptive analytics indicates that sales decreased by 20% in July, it is needed to determine why, and the logical next step is to apply the diagnostic analytics. This form of analytics is used by businesses because it connects more data and identifies patterns of activity. For example, a freight company can employ diagnostic analytics to determine the cause of sluggish shipments in a particular region. The knowledge gathered from descriptive analytics is applied to predictive analytics (Appelbaum, Kogan, Vasarhelyi, & Yan, 2017) and seeks to answer the question, “what is likely to happen?” This type of analytics uses past data to make predictions about future events. Therefore, forecasting is the core of predictive analytics. Advanced technology and manpower are required to forecast this analysis, which is based on statistical modelling. Sales forecasting, risk assessment, and customer segmentation to determine customer profitability are examples of commercial applications for predictive analytics (Appelbaum et al., 2017). Prescriptive analytics is at the forefront of data analytics, incorporating insights from previous analyses to determine the best course of action to take in response to a current problem or decision. The prescriptive model uses information about what happened, why it happened, and a variety of “what-might-happen” evaluations to assist the users in selecting the best course of action to take to avoid a future problem. Prescriptive analytics simplifies 14 the implementation and management of sophisticated tools and technologies such as algorithms, business rules and machine learning. Artificial intelligence (AI) is an excellent example of predictive analytics. Artificial intelligence (AI) systems absorb a significant amount of data in order to learn and make intelligent decisions, and well-designed artificial intelligence (AI) systems are able to communicate and even react to their decisions. Prescriptive analytics and artificial intelligence (AI) are currently being used by most large data-driven organisations (e.g., Apple, Facebook, Netflix, and others) to improve decisionmaking. 3.2 Importance of Data Analytics in Accounting Data analytics is undoubtedly one of the most transformative technological breakthroughs that has impacted the accounting profession over the past few decades (Schmidt, Riley, & Church, 2020). By integrating accounting data analytics, companies can make efficient business decisions and meet external capital providers coupled with capital market participants’ expectations. The importance of data analytics in boosting a company’s performance is well recognised (Wixom, Yen, & Relich, 2013). Accounting data analytics supports companies to confirm that the business is operating efficiently; for example, healthcare organisations can use accounting data analytics to reduce costs (i.e., less waste and fraud) while improving the quality of care (i.e., safety and efficacy of treatment) (Srinivasan & Arunasalam, 2013). In addition, data analytics helps accountants to track the performance of the organisations and take necessary actions when they detect any deviations. This dataanalytical evaluation is important for the long-term feasibility and existence of a company. Accounting data analytics opens up new potential for accountants to offer additional value-added services to their clients, such as auditors can provide more precise recommendations with less margin of error by continuously monitoring of larger datasets, tax accountants leverage data science to quickly examine difficult tax questions that are likely to 15 be introduced to improve users’ experience. This can help in attracting new customers and increasing the percentage of customers who remain loyal to the company over time. The output of data analytics often includes sensitive information that raises concerns about confidentiality or privacy (Schneider et al., 2015). As a result, data misuse can exacerbate potential risks for businesses from various sources that are both internal and external. Accounting executives are well known about these risks, and they are also well trained in how to deal with these risks. Accounting data analytics can support in identifying the areas of these business risks that are being challenged by a company and introduce predictive data analytics to make an efficient business decision regarding specific business risks. Accounting data analytics can be used to uncover the behavioural patterns of customers. These patterns can help companies to develop analytical models that are likely to be used in the future to discover investment opportunities and increase a company’s profit margins (Poddar, 2021). Therefore, accounting data analytics can enhance a company’s profit margin coupled with maximising the wealth of its owners. To maintain the highest level of financial viability, every organisation should regularly evaluate cash flow and optimisation opportunities. Many people were unable to generate cash during the COVID-19 emergency due to forced business closures, lockdowns, stay-at-home directives, and widespread fear of virus transmission (Clayton & McKervey, 2020). While these events are difficult to predict, a clear cash flow picture can help mitigate the suffering associated with such disruptions. Businesses can use data analytics to better understand and manage their sales, inventories, receivables, and client segmentation, which is especially critical during the recovery (Clayton & McKervey, 2020). It can be stated here that data analytics provides detailed insights into the sources and uses of cash and makes it possible to assess the health of both ends of the supply chain. 16 3.3 Emerging Accounting Technologies Several data analytics in accounting might support a firm’s auditing and accounting processes. Explanations of those approaches are documented below. 3.3.1 Deep Learning Deep learning is an emerging artificial intelligence (AI) technique for analysing large amounts of data to uncover complex and abstract patterns hidden within the raw data (Sun & Vasarhelyi, 2018). Deep learning shows the deeper structure of events and situations in several layers of neural networks by combining the information with more advanced methods (Poddar, 2021). For example, existing data is likely to be used to generate an automated algorithm for specific audit judgement, such as lease categorisation, bad debt calculation, etc. (Poddar, 2021). Several companies across the world are outsourcing deep learning projects in their research centres, for instance, IBM, Watson and others. Renowned accounting firms have invested a significant amount of money in deep learning and artificial intelligence (AI). Deep learning assists in decision-making throughout the audit process, including planning, internal control review, substantive testing, and completion (Sun & Vasarhelyi, 2018). Companies now understand the importance of deep learning in accounting data analytics so that they can use it in their accounting and auditing processes. 3.3.2 Blockchain Technology Blockchain stands for a decentralised information and accounting system that allows for the control and validation of payment transactions while avoiding currency duplication or digital multiplication (Abad-Segura, Infante-Moro, González-Zamar, & López-Meneses, 2021). Using block chain technology, accounting data can be securely stored, instantly shared, and validated by anybody with an interest in this issue (Dai & Vasarhelyi, 2017). Blockchain can serve as an alternative ledger system for accounting records (Coyne & McMickle, 2017) and can help advance accounting information from a double-entry system to a triple-entry 17 system (Abad-Segura et al., 2021). This blockchain is likely to be used to store programs that run only when predetermined conditions are met, and these programs are known as Smart Contracts (Poddar, 2021). These smart contracts have several benefits. For example, if an outlier reaches 100% of the median value of transactions, the auditor and the company agree that it is time to evaluate the data using the human eye (Poddar, 2021). Therefore, blockchain is likely to be introduced to identify such outliers and direct them to the auditors. 3.3.3 Predictive Analytics Predictive analytics is an advanced analytical tool that can be used to identify real-time insights and predict future events by analysing historical data (Poddar, 2021). Predictive analytics allows organisations to foresee the future, predict outcomes, uncover opportunities, uncover hidden threats, and take quick action to run their business and make insightful future investment decisions. Thus, this predictive analytics has a great potential to support businesses significantly. 3.4 Tools of Accounting Data Analytics A company can use numerous tools to identify its financial performance and position from several angles. Organisations can process their data using the following accounting data analytics tools. 3.4.1 Microsoft Excel Microsoft Excel is a spreadsheet application used for Windows, macOS, Android and iOS and is widely used by businesses worldwide. It has a wide range of features such as calculation of data, summarising numbers, pivot tables, graphing tools, etc. Microsoft Excel can perform statistical analyses like regression modelling. Microsoft Excel is one of the most significant and robust data analytics tools in the market, and it enhances the efficiency and effectiveness of user expectations. 18 3.4.2 Business Intelligence Tools Accounting professionals might benefit from business intelligence tools that help them to identify sustainable and predictive insights from a particular dataset. By using a variety of business intelligence tools, a company can clean the data, model data and create easy-tounderstand visualisations (Poddar, 2021). This visualisation provides detailed understandings and helps identify areas that require further development. Such tools generate some shared features that can be easily accessible and understandable to other members of the group. There are various business intelligence tools such as Datapine, Tableau, Power BI, SAS Business Intelligence, Oracle Business Intelligence, Zoho Analytics, Good data, etc. 3.4.3 Proprietary Tools A proprietary tool is a tool that is devised by a company for its own use. A company internally develops and utilises this tool to produce and sell products and goods/services to its users and customers. Large companies usually introduce proprietary tools such as Interactive Data Extraction and Analysis (IDEA). The IDEA is a software application that allows accountants, auditors, and finance professionals to interact with data files. 3.4.4 Machine Learning Tools Machine learning is a data analysis technique where a software model is trained using data. It is a field of artificial intelligence based on the premise that systems can learn from the training data, identify patterns, and make judgments with minimal human interaction. Several companies across the world use the most advanced and sophisticated tools in their data analytics in accounting procedures such as “R” and “Python”. These programming languages are mostly employed by companies to perform highly customised and advanced statistical analyses. Python is one of the fastest-growing programming languages available today. Python was originally developed as an object-oriented programming language for use in software and web development but later extended for use in data research. Python can 19 perform a wide range of research on its own and integrate with third-party machine learning and data visualisation software. On the other hand, R is a popular statistical programming language that statisticians use for statistical analysis, big data analytics, and machine learning. Facebook, Uber, Google, and Twitter use R for behavioural analysis, advertising effectiveness, data visualisation and economic forecasting. Both of these programming languages are used to generate various algorithms that perform regression analysis, detect data clusters and perform other programming tasks. 3.5 Data Analytics in Auditing Due to the massive and rapid technological advances, companies are continuously developing technologies to improve their business strategy and day-to-day operations. Among these technologies, data analytics has gained popularity across a wide range of organisations, from corporate and government to scientific and academic disciplines, including accounting and auditing (Dagilienė & Klovienė, 2019). According to the Institute of Chartered Accountants of England and Wales [ICAEW], it is vital for the audit profession to keep up with these changes and be proactive in examining how new technological trends may affect auditing methods (Joshi & Marthandan, 2018). Therefore, accounting professionals around the world need to adapt to these technological disruptions. Audit data analytics is believed to have a greater depth of capabilities and broader concept than standard analytical methods because it involves powerful software tools and statistically demanding methodologies (Joshi & Marthandan, 2018). Auditors need to adapt data analytical skills and big data technologies to efficiently execute their operational functions. Both internal and external auditors use data analytics to perform audit functions such as continuous monitoring, continuous auditing, and full-set analysis when sample audits fail to produce a good quality of results (Vasarhelyi et al., 2010; Protiviti, 2020). Data analytics helps auditors to extract useful insights from large volumes of 20 datasets in real-time, allowing them to make evidence-based decisions. In addition, data analytics may assist auditors in the following areas – a) Providing audit evidence by analysing the general ledger systems of corporations in-depth (Malaescu & Sutton, 2015). b) Detecting fraud and improving other aspects of forensic accounting (Joshi & Marthandan, 2018). c) Assisting in the detection of anomalies and trends, as well as the comparison of industry data in risk assessment (Wang & Cuthbertson, 2015). d) By incorporating external data, auditors can provide services and resolve issues for clients that are beyond their current capabilities (Earley, 2015). The American Institute of Certified Public Accountants [AICPA] and Rutgers Business School announced a research initiative in December 2015 that focused on the advanced use of data analytics in auditing (Tschakert et al., 2016). The initiative’s aim was to develop a better understanding of how data analytics can be integrated into the audit process improve the quality of auditing work (Tschakert et al., 2016). Potential advances in data analytics include higher-quality audit evidence, minimising repetitive tasks, and better correlations of audit tasks with risks and assertions (Tschakert et al., 2016). Both the AICPA Assurance Services Executive Committee and the Auditing Standards Board Task Force are working on a revised audit data analytics guideline that will be more acceptable and workable than the existing analytical procedure guideline. The new guideline will adopt most of the existing audit analytical procedure guidelines but will also introduce separate guidance on how audit data analytics can be integrated into the overall audit process (Tschakert et al., 2016). Another project is also underway to develop voluntary audit data standards that are likely to support the extraction of data and expedite the utilisation of audit data analytics, and 21 a mechanism to illustrate where audit data analytics might be implemented in a typical audit program (Tschakert et al., 2016). 3.6 Data Analytics in Financial Accounting Implementing data analytics can help a company to increase its profit margins and gain a competitive advantage. For example, according to a recent survey of accounting professionals conducted by software vendor Sage (2018) of 3,000 accounting professionals globally, 56% of accountants believe their practice revenue has risen over the last 12 months due to the adoption of automation. Companies with a limited application of data analytics in their business operations may be forced out of business in the long run. Data analytics is the most important area where technological transformation can happen fast enough for an organisation and its senior-level executive to adapt. Thus, the change management concept may be considered to take advantage of data analytics. The measurement of accounting information has increasingly lost its informational value due to the significant decline of market value explanation provided by accounting variables (Lev & Zarowin, 1999). However, this decline in information value is particularly evident for emerging knowledge-intensive businesses with a higher intangible intensity, which claims a steadily expanding share of a country’s economy (Srivastava, 2014). The realtime processed data has been appreciated by the economy which is measured through quarterly or annual financial statements (The Economist, 2002; Vasarhelyi & Greenstein, 2003). It is considered to be the most useful information for the external capital providers and capital market participants to understand and interpret the information so that effective decisions can be made (Krahel & Titera, 2015). Current technologies of accounting recording systems are providing more absolute measurements in terms of intangibles, inventory valuations (e.g., LIFO, FIFO) and estimation of depreciation compared to traditional accounting and reporting systems (Lev & Zarowin, 1999; Lev, 2000). For example, most 22 students feel unable to learn several old-fashioned inventory accounting methods, while recently, firms are integrating radio-frequency identification (RFID) or barcodes to measure and report the actual inventory (Vasarhelyi et al., 2015). Another set of real-time financial statements reveals more accurate and real-time business-related information compared to traditional accounting and reporting systems that help the internal and external user to make efficient and convincing investment decisions (Gal, 2008). This technology-enabled reporting provides more relevant and descriptive disclosure, supporting the analysis and provisioning of management, auditor, and stakeholder dashboards. Thus, the value of the traditional accounting methods that report information has lost its appeal to information users such as external capital providers and several capital market participants. Businesses have added a large amount of data to their traditional data repositories, resulting in massive databases in their ERP systems, of which only a small portion is relevant for financial reporting. Although these “structured data stores” in ERPs are large, they could be overwhelmed by increasing the amounts of less structured data. 3.7 Data Analytics in Management Accounting Data analytics in management accounting can be defined as how information technology tools are implemented to analyse and interpret a company’s managerial activities (Spraakman, Sanchez-Rodriguez, & Tuck-Riggs, 2020). The traditional role of management accountants has focused on participating in management decision-making, designing, planning, and performance management systems, budgetary control, product profitability, and assisting senior management in formulating and implementing organisational strategies (Association of Chartered Certified Accountants [ACCA], 2020). However, as big data and data analytics become more prevalent, their current practices, working data and tools, interactions with management and other departments, and requests for new areas of competence are all likely to expand (Nielsen, 2018; Tiron-Tudor, Deliu, Farcane, & Dontu, 23 2021), which include channel profitability, predictive accounting, and business analytics (Appelbaum et al., 2017). Data analytics is viewed as a critical skill for any accounting professional. Currently, management accountants are uniquely prepared to assess an organisation's data requirements because they have a comprehensive understanding of it and its existing information systems. This helps them to delve into both financial and non-financial data to drive better decisionmaking (Association of Chartered Certified Accountants [ACCA], 2020; Tiron-Tudor et al., 2021). Therefore, management accountants must comprehend data analytics and be able to convey their findings to upper management, as well as have the business understanding and commercial acumen to assess data analytics results and provide significant commercial analysis and supply suggestions. Management accountants also use data analytics to add value by improving productivity, profitability, and cash flow, as well as managing customers, innovation, and intellectual property, which focuses on new perspectives and ensures business organisations’ long-term viability. From the academic perspective, although researchers have demanded that prior research on data analytics in management accounting lacks sufficient empirical evidence (Cokins, 2014; Dinan, 2015; Lin, 2016), several conceptual papers have explored the implication of data analytics in management accounting (Schneider et al., 2015; Appelbaum et al., 2017). Vasarhelyi et al. (2015) illustrate how accounting evolved from paper-based aggregate information records through charts of accounts/general ledgers and then to big data or data analytics. Consistent with this notion, Pickard and Cokins (2015) argue that accountants are in the best position of a business, allowing them to own and drive a huge number of data analytics to make effective business decisions. They also report that data analytics are likely to be incorporated by the accountants so that they can analyse data ranging from general financial ratios to more sophisticated data analytics techniques such as 24 clustering, regressions, and factor analysis. Similarly, Schläfke, Silvi, and Möller (2013) document that accountants have prior knowledge of financial reporting and can therefore implement various contemporary data analytics tools to prepare several financial and nonfinancial reports. Moreover, Marr (2016) reports that 45 companies throughout the world are using big data in management accounting such as Walmart, Netflix, Amazon, and Airbnb, etc. Nielsen (2018) argued that management accounting research should capitalise on the opportunity provided by the data analytics movement to develop theories and ideas for factbased judgments with high external validity. Similarly, Arnaboldi, Busco, and Cuganesan (2017) look into the interaction between technology-enabled networks and the accounting function to spur more research and debate on the topic. 4. Artificial Intelligence (AI) in Accounting Artificial intelligence (AI) is the simulation of human intelligence in machines. It allows machines to think, learn and solve problems in the same way that human brains do. The use of artificial intelligence enables machines to perform the necessary tasks by mimicking the behaviour of human intelligence. Several companies worldwide have implemented artificial intelligence (AI) in their accounting functions and analysis in order to obtain the benefits of artificial intelligence (AI). For example, according to a recent survey of 3,000 accounting professionals globally conducted by software vendor Sage (2018), 66% of accountants believe they will invest in artificial intelligence (AI) to automate repetitive and time-consuming tasks, while 55% assert they will use artificial intelligence (AI) to improve their business operations. Artificial intelligence (AI) was first introduced into accounting more than 30 years ago (Abdolmohammadi, 1987; Brown, 1989). Specifically, artificial intelligence (AI) was employed in financial accounting and auditing in the late 1980s and early 1990s (Barniv, Agarwal, & Leach, 1997; Etheridge & Sriram, 1997). After this period, significant advances 25 were made in other areas of accounting and finance. Companies throughout the world are reaping enormous benefits by integrating artificial intelligence (AI) into accounting tasks, which can be classified as internal or external. For internal purposes, artificial intelligence (AI) is used in accounting functions to produce more accurate and acceptable financial statements. Artificial intelligence (AI) can offer information faster than humans due to its competency and consistency in analysing and interpreting accounting data (Petkov, 2020). As a result, the accounting functions performed by artificial intelligence (AI) can provide quick and accurate output. This instant output improves the timeliness of accounting information and helps users in making informed decisions. Artificial intelligence (AI) that has been well-trained to attain accuracy, i.e., that has been programmed to follow accounting rules, would produce more accurate and consistent accounting information. Consistent with this notion, incorporating artificial intelligence (AI) in accounting functions can eliminate accounting errors and human errors when preparing financial statements. Furthermore, several companies throughout the world have adopted artificial intelligence (AI) with predefined “trained principles”, and these companies are benefiting from improved financial reporting comparability. Accounting firms are currently integrating artificial intelligence (AI) into auditing functions to ensure compliance and reduce managers’ intentional errors. This would limit the ability of managers to use certain formulants’ financial functions. Despite the fact that just a few accounting firms have included artificial intelligence (AI) in their auditing functions, the majority of them use artificial intelligence (AI) to manage audit risk (Zhao, Yen, & Chang, 2004). Furthermore, the most notable benefit of incorporating artificial intelligence (AI) into a company’s accounting function is the minimisation of future costs. In the long-term, reliance on artificial intelligence (AI) will reduce having to depend on human operations and improve the efficiency and accuracy of a company's financial reporting. Primarily, there are 26 certain fixed costs associated with the design, development, and implementation of artificial intelligence (AI) in a company's accounting function, as well as some indirect costs associated with monitoring and confirming artificial intelligence (AI)’s performance. Furthermore, another important cost of artificial intelligence (AI) is its reliance on the entire system because if the system is hacked/attacked and no human backup assistance is available, it will become a liability rather than an advantage to the company (Petkov, 2020). For this reason, proper maintenance of the artificial intelligence (AI) system is an important function of a company before implementing artificial intelligence (AI). Moreover, Petkov (2020) identifies the following potential accounting functions (as shown in Table 3) that can be delegated to artificial intelligence (AI). 27 Table 3: Potential accounting functions to delegate to an artificial intelligence (AI) Human Functions Cash Accounts Receivable (A/R) Inventory Artificial Intelligence (AI) Functions Manual Input of Cash Receipts and Payments [Use of Journal Entries (hereafter, J/E)].

Conclusion This chapter aims to provide an overview of the growing role played by big data, data analytics, and artificial intelligence in the accounting profession. Big data, data analytics, and artificial intelligence (AI) have become emerging buzzwords for accounting professionals in recent years. It is becoming increasingly important for accounting professionals to understand the possibilities that big data and data analytics offer to their clients and the industry. Accounting is data-driven, and subsequently, big data can assist accounting professionals in delivering greater value to their clients. Accounting professionals’ job responsibilities are rapidly changing due to the development of big data, data analytics, and artificial intelligence (AI). It is argued that these emerging technologies pose a threat to accounting professionals. Experts argued that anyone who does not embrace this change and appreciate the new technologies would be left behind (Chartered Institute of Management Accountants [CIMA], 2022). However, accounting professionals have long-standing reputations in the market for their outstanding technical and problem-solving skills as well as their ability to make datadriven decisions. In fact, a recent survey of accounting professionals conducted by software vendor Sage (2018) reports that 83% of clients now have higher expectations from their accountants than they did five years ago. Sage (2018) also reports that 39% of accountants describe themselves as early adopters of technology after surveying among 3000 accountants globally. Individuals who are able to discern patterns in data and translate them into compelling strategic narratives will find themselves at the centre of the twenty-first-century business world (Association of Chartered Certified Accountants [ACCA] and Institute of Management Accountants [IMA], 2013b). Therefore, in a rapidly changing business environment, accounting professionals can seize numerous opportunities by leveraging big data, data analytics, and artificial intelligence (AI) to stay ahead of the competition. 29 References Abad-Segura, E., Infante-Moro, A., González-Zamar, M.
