Can my Customers book several Appointments in one Step?

If you activate Multiple appointment selection at Scheduling Page > Settings > Advanced Settings, your customers will be able to book several appointments on any available days in one step without going through all the booking steps each time.

If you only want to enable multiple appointment selection for certain services, then go to the menu Company > Services > desired service [Edit] > Service-specific Settings > Multiple appointment selection.

Depending on the service, you can also specify how many appointment slots must be selected in order to complete the booking.
To do this, switch to the Advanced Settings tab in the affected service. There you can edit the "Number of appointment slots that must be selected " option.

Since these are individual appointments, your customers will also receive a separate confirmation for each appointment.
