To process a void you need to ensure the transaction is still in an open batch. A transaction can only be voided if and only the batch has not been settled and submitted to the bank for deposit. If a settlement has already occurred you will need to do a refund.
***PLEASE NOTE: when a transaction is voided, the sale and the void transactions will not appear on the customer's credit card statement.
2) A list of all the recent transactions will appear. Select the one you would like to void.
3) Click the VOID button in the top right corner.
