Next to keeping your customers satisfied, getting them to pay you in a timely manner is one of the most important tasks in running a small business.
There are three things you need to keep on top of: who owes you money, contacting late payers, and tracking how long it takes a customer to pay you.
To find out who owes you money (and for how long) run:
Aged Receivables [Summary] report
If you need to prepare a "dunning list" for contacting late payers run:
Aged Receivables [Detail] report
To review how long it takes your customer to pay you, print:
Customer Payments [Closed Invoices] report
For the payment history of a single invoice, print:
Invoice Transactions report
Note: Once you settle on the list of reports you like to run every month, consider creating a report batch for them. Refer to What's a Report Batch? for more information.
