here are several issues to be aware of when you analyze based on an aging report, which are:
Individual credit terms. Management may have authorized unusually long credit terms to specific customers, or perhaps only for particular invoices. If so, these items may appear to be severely overdue for payment when they are, in fact, not yet due for payment at all.
Distance from billing date. In many companies, the majority of all invoices are billed at the end of the month. If you run the aging report a few days later, it will likely still show outstanding accounts receivable from one month ago for which payment is about to arrive, as well as the full amount of all the receivables that were just billed. In total, it appears that receivables are in a bad state. However, if you were to run the report just prior to the month-end billing activities, there would be far fewer accounts receivable in the report, and there may appear to be very little cash coming from uncollected receivables.
Time bucket size. You should approximately match the duration of the time buckets in the report to the company's credit terms. For example, if credit terms are just ten days and the first time bucket spans 30 days, nearly all invoices will appear to be current.
Unapplied credits. There may be unapplied credits on the report. If so, clean up the report by researching which invoices they should have been applied against. Doing so may reduce the amount of overdue receivables listed on the report.
