To perform a partial credit card refund in PetExec: (the steps are the same as for a full refund, you just change the amount of selected service in the refund order)
Begin in the pet owners purchase history. From the owner menu-->purchase history.
Click on the order ID for the order you want to refund, it is always best to perform a refund against the original order. To refund back to a credit card, you must have an existing order with a credit card transaction.
From the next page, click the Apply Refund button:
On the owner refund screen:
Cardpointe does not allow partial refunds on transactions that have not been batched. If you are trying to issue a partial refund and the refund page reads "Cardpointe VOID" instead of "Refund to CardPointe", then the transaction has not yet been batched. This often happens if you are trying to complete a partial refund for an order that was processed on the same day. If you have the credit card on file, you can try voiding the entire amount and then re-processing the correct amount.
