How far ahead, minimum notice, new clients

Settings → Booking:

• How far ahead your diary opens — a rolling window. 12 weeks means nobody can book more than 12 weeks out. Front-desk bookings aren't limited.
• Minimum notice — how close to the appointment time a client can still book online. 2 hours stops the 9am booking made at 8:55.
• Taking new clients — switch it off and only clients already on your book (matched by email) can book online. Your team can still add anyone from the calendar. The page says *existing clients only* so new people know to call.
