Charging interest on overdue invoices is the imposition of a fee on unpaid invoices that have exceeded their payment deadline. For instance, a business may charge a 1.5% monthly interest rate on invoices that are more than 30 days past due.
This practice plays a crucial role in business operations by compensating businesses for the opportunity cost of delayed payments, encouraging timely payments from customers, and providing an incentive for prompt payment. Historically, the concept of charging interest on overdue invoices can be traced back to medieval times when merchants imposed penalties for late payments.
