Many businesses do not use bill-by-bill with some of their customers. There are cases where the nature of the business does not support bill-by-bill. Customers make lump-sum payments as and when they want to. You might still need to analyze debtor performance by asking this question “assuming I give 5 days credit, is my customer meeting my expectations?” With this Add-on, you can specify the ‘credit period’ (called Rebate Days here), specify a rate of interest and obtain a report which will show you the cost of money for any debtor.
