We want to make it easier for you to hire and retain staff by increasing their access to gratuities, so we've given you the ability to let customers add a gratuity to their online bookings.
Gratuity-related settings can be found in: Admin->System Configuration->Gratuities
Want to be a bit more assertive about gratuities?
You can optionally suggest a default online booking gratuity rate (customers can still override that rate or opt-out if they want).

You can customize the percentages and their corresponding messages under Reservations->Online Gratuity Options.
Looking for more ways to increase your gratuities?
You can also add a gratuity button to your followup emails, and your retail-only receipts:
