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.

Try it: James Spa
Open Bookable services
James Fernandes opens the Bookable services screen from the Appointments
module to set up how his treatments book.
Set duration and capacity
For “Aromatherapy Massage” he turns on Bookable, sets the duration to
60 minutes, and sets parallel capacity to 2 — the spa has two massage
rooms.
Add a turnover buffer
He adds a 15-minute buffer so the room can be reset between clients,
which automatically spaces those bookings apart on the agenda.
Book against it
Now when Priya books that service, the end time and the two-room limit
are applied automatically — see Booking
basics.
