BookOn is a system with “Group Appointments” feature. If the service is a group service, more than one customer can make an appointment for the same timeslot. If your customers do not want to come alone and want to bring someone else with them, they do not need to make a separate appointment for each person he brings. Because with the newly added “Bring people with you” feature, your customer can choose how many people to bring with him.
For this option to be active, you must first set your service capacity as Group.
You can also specify the minimum/maximum number of people your timeslots are suitable for.
