What it is
Appointment scheduling for service businesses: multiple appointment types, session packages and memberships, intake forms attached to the booking, and payment taken at the time of booking.
Best for
Coaches selling ten-session blocks. Acuity can hold the package balance and decrement it as sessions are booked, which otherwise lives in a spreadsheet you forget to update.
Watch out for
No free tier, and the configuration surface is large — appointment types, packages, forms and availability rules interact in ways that take an afternoon to get right.
