If you’ve accidentally paid the wrong orders / put in the wrong amount in a batch payment, here’s how to reverse it:

1. Go to Main Menu > Sales > Customer List and find the customer whose payment you need to correct.
2. Double click on the customer name to bring up the record, then click on the Payment History tab at the bottom right.
3. In this table, look for the Batch Payment you want to reverse and double click on it.
4. Click the arrow button beside OK and select Delete Batch Payment.

Note: This removes the payment on all affected orders, so if you only need to correct the payment of a single order, you will need to re-complete the batch payment for the other orders to remain paid.
