To add tips to bookings, you first need an add-on for them. You only need to set this up once.
How to set up a Guide Gratuity add-on
Click Add-ons in the left sidebar (under Products).
Click + New add-on (top right).
In Name, enter Guide Gratuity.
Leave Default price at $0. You'll enter the actual tip amount on each booking.
If you charge sales tax, any tax set as an add-on default applies to this add-on automatically. If tips shouldn't be taxed in your area, turn on Override next to Sales tax and remove those taxes.
Click Save.
