No you don't have to. It's your choice.
- if (and what) you send your customers when provisionals are made online
- if you send notifications to the store when online provisionals are made
- if you auto-cancel online provisional that are not paid for (and after how long)
here is where you make the setting in BRM:
system -> settings -> online
in this example they have decided to effectively ignore all online bookings until paid
- no customer email
- no store email
- auto cancel it after 120mins - if not paid in that time.
In this example they have decided to keep proviosionals
(it depends how many bookings you get, amongst other factors)
- provisional emails
- shop emails
- no auto-cancel (timeout)
