Jezzam's membership features allow you to give different groups of your customers access to different types of bookings.
You might use these features for a number of different reasons. For example:
1) Your business works on a membership model
2) You don't want public access to online bookings but want to allow online bookings only after your customers have logged in
3) You want members to book online with one set of services. The public can also book but they book a different set of services (for example, with different pricing)
4) You have different categories of member (for example, Bronze, Silver and Gold) who can booking different services and/or classes, events or workshops
