The payment you want to reverse should be displayed.
Note: If you see Delete in the Edit menu but you want to reverse a transaction
After a few moments, a transaction in the opposite amount of the payment -- a reversing transaction -- will be displayed in the Receive Payments window.
If you're reversing a payment from a previous accounting period, consider assigning a date from that period to the transaction you just created. This will allow your reports for that accounting period to reflect the proper amounts.
If the payment you reversed was originally used to fully pay a sale and any discounts for prompt payment applied to the sale, a message will appear. If you receive this message, continue to step 4.
If no prompt-payment discount message appears, continue to step 5.
Choose Reverse Payment from the Edit menu, then click the Record button to reverse the discount.
If the payment has been recorded on a Prepare Bank Deposit transaction; that is, the original payment doesn't appear in the window: Select the payment reversal (a negative amount) from the list of payments by clicking the Deposit column.
