You are able to set up a specific booking lead time, so you can determine how much notice you'd like before new online bookings can be made.
There are several places that this can be configured - at a global business level, and then also at a service and staff member level. If only the business level is set, this lead team will be applied as the default to services and staff member lead times.
If they are different, the staff member's booking lead time takes precedence for non-course bookings, then the service, then the business level lead time.
