You can pre-authorize a credit card for a specified dollar amount—thereby guaranteeing payment—before adding items to the customer's order (e.g., in the case of a bar tab).
To pre-authorize a card:
- On the Order screen, tap Actions > Pre-authorize card.
- Enter the amount you would like to pre-authorize.
- Insert or swipe the card when instructed.
Once the authorization is approved, you will see the pre-authorized balance marked in green. As you add items to the order, their costs will be deducted from the pre-authorized amount.
When you are ready to close the order, go to the Payments screen and tap Finalize. You may then adjust the Tip as needed.
