Before you can book appointments, you tell BillBasket which of your services are bookable and how each one behaves on the calendar — how long it takes, how many can run at the same time, and whether to leave a gap between bookings. This is what makes the booking form fill in end times and stop double-booking automatically.

Understanding the fields

On the Bookable services screen, each service has:
  • Bookable (toggle) — whether this service shows up as an option when booking an appointment. A service you sell over the counter but never book a time for can stay off.
  • Duration (minutes) — how long the service takes. This is what the booking form uses to fill in the end time automatically, so a booking’s length matches reality without anyone doing the math.
  • Parallel capacity — how many of this service can run in the same time slot (for example, 3 if you have three chairs). BillBasket blocks a booking once a slot hits this number. Note the interaction with staff: if you assign a specific provider to a booking, that provider can only do one at a time regardless of this number — so capacity is the upper limit, and an assigned provider narrows it to one.
  • Buffer (minutes) — a gap left after each booking (for cleanup, turnover, notes) before the next one can start. Increasing the buffer effectively spaces bookings further apart.
  • Colour — an optional colour to tell services apart at a glance on the agenda.
