When Accounts Receivable invoices are entered, they immediately are posted to the customer account and to the Aged Accounts Receivable list. This report will show you who owes you money, how much, and how long it has been outstanding in the current, 30 day, 60 day and 90 day coloumns.
As an option, you can reprint this report for any time back in history. This is very important as you might start invoicing in the current month before being finished with the system in the previous month and printing that report. Most of our competitors cannot print the reports for previous months even if they let you enter data for the previous months - a huge shortcoming of those systems.

Note that you can double click on a customer on this report on screen and jump directly to the customer record, from there, you can view the invoice history and bring up a particular invoice if you need to. When you’re finished, you return to the Aged A/R report where you left off.
