To void/refund credit cards:
First, go to View All Orders.
To view all settled orders, select the Filter button. Scroll down to Advanced Options and then select View All Settled Orders. Locate the ticket that needs to be refunded, and select the three bars or the "triple patty" button to the right of the ticket.
Then select, Refund Order.
Select the card that needs to be refunded.
If multiple credit cards were used for payment, then there will be more than one form of payment listed to choose from.
There will be a prompt to confirm the payment amount, as seen above.
If the refund being issued is a partial amount of the total, then select clear and enter the correct amount that is being refunded to the customer.
In the description box, enter the reason for issuing the refund.
Confirm the refund by selecting, Yes.
Make sure the bank/drawer that the transaction was settled to is still opened. If the bank is no longer opened, you can not perform the refund. The credit card device will need to be on and operating to perform the refund as well.
