Customer satisfaction is a customer-based way of measuring a firm’s performance by assessing whether perceived benefits of a product or service meet or even exceed customers’ expectations. It has been often assumed that satisfied customers are good for business. However, is a satisfied customer a profitable one? Connection between customer satisfaction and spending behaviours has been found to be weak. It turns out that “changes in customers’ satisfaction levels explain less than 1% of the variation in changes in their share of category spending.” Good real-life examples are Walmart and McDonalds, which both score lower satisfaction levels than their big competitors but have the largest market shares in their industries. This can be explained by their broader customer appeal. This means that their customers are more diversified, therefore it is more difficult to satisfy everyone’s needs, but at the same time their market share is bigger. Providing customer satisfaction can be costly to a company. One way to satisfy a customer is to provide them with a high quality product or service or keep improving the ones already existing. It might, however, turn out that costs incurred in product development are higher than the benefits received from a slight improvement in customer satisfaction. There are however also positive links between customer satisfaction and profitability. If not by increasing sales revenues, customer satisfaction can be a factor contributing to lowering of some costs. A strong connection has been found between customer satisfaction and loyalty – which ensures more customers repurchasing in the future. Therefore the costs of attracting new customers are lowered. Moreover, reduced price elasticity can be observed with satisfied and loyal customers. This means they are less sensitive to price changes and therefore increase their profitability. High customer satisfaction has a positive influence on the company’s image. One of the ways prospective customers find out about the existence and quality of the products or services offered is through the businesses’ current customers. Satisfied ones are more likely to engage in a positive word of mouth and in this sense they are profitable, since more customers means more sales. In conclusion, the connection between customer satisfaction and profitability is not so clear as it might be superficially assumed to be. On the contrary, there is a number of arguments against that assumption. In my opinion, however, it is important to find the right balance. Even though customer satisfaction is definitely not the only or the most important variable influencing a business’ profitability, it is still important for a company to take into consideration customers’ needs and provide customer value as a way of achieving corporate goals.
