How do I edit a credit?
There are 2 ways to edit a credit. If the customer has a credit on their account it means that you either
1- added a credit without payment or
2- made a payment for more than what was due (there was a surplus).
To edit a credit balance, you either need to edit the line item on the billing history that was created when a credit without payment was given or find the payment in the billing history and edit the amount of the payment to reflect the true amount of the payment (if a payment was made for an amount bigger than it was supposed to be for). To edit, click on the date of the credit added.
