You can control how your customers request or book Appointments, Classes, and Store purchases.
Step 1: Go to Settings > Member Area
Step 2: Under Available Features, turn on the features you would like to have booked online: Appointments, Class, Store.
Step 3: Customize the features.
Scroll about 3/4 down the page and you will see options for Class, Appointments, and Other (store).
To offer members predefined appointment templates to choose from (for example, a set duration & price), then you would enable the Only allow clients to book in by choosing a Service, which uses my Appointment Templates list.
Once you've chosen your preferred settings on how session bookings are handled, your clients can start making online appointments & class bookings through either your Client Area Website or through the Mobile Apps.
