Your booking products will typically be set up for you by your local Nettl studio.
For a customer they will be able to make a booking by going to a booking page, choosing on a calendar for the available dates.
Your bookings could require confirmation first, in which case when they order they check availability, or could pay online straight away and have the booking reserved for them.
When the booking is placed you will be sent an email of the booking and asked if you need to confirm availability.
When the booking is completed or reserved the customer is emailed.
