Difference 1
It books appointments, not grooms
A general booking tool stores a customer and a time slot. Grooming needs more: the dog, its breed and coat, how it behaves with a dryer, its vaccination status, what was done last visit, and a service duration that differs between a full groom and a nail trim.
SmartGroom is built the other way round. The pet is the record: breed, coat notes, behaviour, vaccination history and past grooms, held against the appointment you are about to do.
Difference 2
How you pay for it
Square Appointments is sold on a subscription basis with payment processing charged separately. Confirm current plans and rates on their own site — we do not publish competitor figures we have not verified.
SmartGroom is a one-time software purchase: $599 for the first 20 salons, $799 after. SMS usage, hosting and domain registration are billed separately, and payment processing runs through Stripe on its own terms.
Worth doing: compare total software cost over the years you plan to keep grooming, not the monthly figure. The calculator does it for you.
