Posting Payments > Posting Account Payments
You can delete payments that have been posted to an account. Only delete bulk payments if you post a bulk account payment to the wrong account or for the wrong amount.
To delete an account payment:
In the Payments window, select the payment and select Delete from the Options section of the Express bar. A message that asks you to confirm the deletion is displayed.
Click Yes.
Run the Account Aging report, including accounts with a credit balance, to generate a list of accounts that are due refunds.
