A number of scenarios can arise in which a user may need to void the payment or payments that were taken to satisfy a customer's bill. This can easily be done in a few taps from the ordering screen.
Find the check in Toast using either the Lookup function, Previous Checks or the Payment Terminal (It will most likely appear in Paid Checks or Closed Checks).
With the check located, tap Pay to enter the payment screen of the check. This is the screen where the payment can be viewed and, if necessary, adjusted.
From the payment screen, tap the existing payment. The line will appear blue to indicate this is the payment has has been selected.
With the payment selected, select the 'Void' option to remove the payment for the check. This can be done for any form of payment; cash, credit or debit, gift card, etc.
This action cannot be undone, so as a safeguard against accidental voids, Toast will prompt the user to confirm the action before it is performed.
Depending on the receipt settings for the device that the void is processed on, the user may also be prompted to select a receipt option for the void. This receipt would be a confirmation to the customer that the void was processed for their records.
Once a selection is made, the user is directed back to the payment screen which now has no payments. In most cases, either a new payment needs to be made or the check as a whole needs to be voided.
To take a payment, proceed with the normal steps for doing so by selecting a payment type on the right, etc.
The option to void the entire order and all items on it, click the overflow menu in the upper-right corner (the stack of 3 grey squares.) Choose the first option, 'Void Order.'
