My transaction processed for a different amount than I intended to charge.
You can void the transaction completely to make sure your customer isn’t charged the incorrect amount. From the main menu in your ROAMpay app select Void and locate the transaction that needs to be canceled. Once you have located the transaction select Void. It will ask you if you’re sure you would like to void the transaction and you can select Void again.
You can also refund the customer the difference in dollar amounts by going to refund, entering the amount to refund and the customer’s card information.
