Checkout add-ons

Present retail items or additional services to clients at checkout before they complete a booking.

Checkout add-ons appear during the appointment booking flow — after a client selects a service type but before they confirm. Use them to offer relevant extras like equipment rentals, extended sessions, or class supplies.

Checkout add-ons appear when clients book appointments online or in the branded app. Retail add-ons shown after a class booking in the branded app are configured differently — see sell retail online.

Add a checkout add-on to a service type

Go to Setup → Service Types and open the appointments list
Click Manage add-ons → Create new
Fill in:
- Name
- Description
- Price
- Duration (extends the appointment)
- Applies to services and Applies to instructors
Click Save changes

Clients see the add-on options during checkout and can include them before completing the booking.

Limitations

Add-ons are for appointment service types — not for group classes
Retail items sold as add-ons through this flow are not deducted from retail inventory
Add-ons don't block room or resource availability
Once a reservation is confirmed, you can't add the checkout add-on retroactively — to sell a retail item after the fact, use the POS instead

Add-ons for physical retail items post-booking

For post-checkout retail (water bottles, swag, mats), use the mobile app add-on flow instead — see sell retail online.
