Allow your customers to tip either in-app or on a printed receipt. When your customers tip on a printed receipt, you'll enter in tip amounts after the transaction.

Note: Customers will sign and tip on a printed receipt. This option prints out a merchant and customer copy of the receipt. Enabling this setting turns off digital signatures and on-screen tips.
To adjust tips:
Note: Enter in tips prior transactions settling at 10 pm ET.
