While I advise all of my clients not reverse receipt and instead do a return receipt, occasionally they will have a problem with a receipt that needs to be fixed. For example, you rang up the wrong item with the same price, but now your inventory will be off. If you reverse a receipt where you have processed a credit card, it will refund the customer credit card, so this is not a good idea. What you can do is to do a return receipt on the same day and process the refund as payment on account. You can either use the customer that was the problem or create a customer called sales receipt corrections. POS will prompt you to use this customer with QBF if you are hooked up to the financial product. Also may prompt you for a credit limit. Finish the return refunding to the "customer's account" Then ring up the sale correctly and in the take payment on account. The refund and payment will cancel each other out and now the inventory will be correct. This technique can be used for many purposes such as changing the date of a sale, etc.
