Within the Booking Settings, users can set up a timeframe that will disallow online client bookings. This will change the time between the first available booking time and the current time. 

For example, if the time is 3 p.m. and the booking time buffer is 1 hour, the first appointment will be available starting at 4 p.m.

Users can set buffer times from 15 minutes to 7 days from the current time.
