When you enable tip processing, the terminal automatically offers preset percentage values to the customer. By default, the preset percentage values are set to 15, 18, and 20, but you can easily change one or more of these values as needed.
To change a preset tip percentage:
NOTE: If you have multiple terminals, you should ensure that they are all configured to offer the same preset tip percentages to avoid one terminal displaying different tip percentages from the other terminal(s).
