If you’d like to offer clients the option to leave a tip when booking an event, you can do this by adding an “Add-on”question to your booking form.
While editing your form:
Click the “+ Add” button in the main content area
Select “Add-on” under the Selling header in the right-hand sidebar
When setting up the add-on, list common dollar amounts that clients can easily select. This makes the tipping process simple and seamless during checkout.
