Adjusting for Overpayments and Underpayments
If a customer overpays or underpays an invoice by an insignificant amount, you can write off the amount in the general ledger.
Overpayments
To directly write off an overpayment to the general ledger, apply the cash receipt to open items and then select the GL check box. Select the account to post the overpayment to. To process the adjustment, click OK.
Underpayments
On the Posting screen, click ADD ADJUSTMENT. On the Miscellaneous Adjustments screen that appears, enter the amount of the underpayment and the account to post to. After you click SAVE, the Where to Apply This Item grid on the Posting screen refreshes, showing the new adjustment.
