Inventory shortages can be a severe issue for JIT companies because there are no buffer stocks, and a supply interruption can result in production being halted, manufacturing workers being laid off, and customer orders not being fulfilled. As a result, it may have a significant impact on the company's profitability and competition.

To cover for a range of deliveries, monthly invoices can be prepared.
