Square Appointments is built around Square's payments and point-of-sale system. If you already take cards with Square, that integration is its biggest strength. SlotSwift is independent of any payment provider and focuses on booking, reminders, and self-service rescheduling at a flat price.

Payments. If you want to take card details at booking, charge no-show fees automatically, and run checkout and booking from one system, Square does that and SlotSwift doesn't. If your card reader is already Square, it's a natural fit.
Square Appointments works best inside Square's ecosystem. If you take payments another way, you're adopting a payment platform just to get a booking page. SlotSwift doesn't care how you get paid: clients book online, receive a confirmation and reminder with a calendar invite, and reschedule themselves - at one flat price that doesn't change per location.
The best test is to book an appointment as if you were your own client, on your phone. SlotSwift takes about two minutes to set up and has a 14-day free trial, so you can compare the client experience side by side before deciding.
No. SlotSwift doesn't process payments, so you can keep using whatever you already use - another card terminal, bank transfer, cash, or payment links.
No. SlotSwift focuses on preventing no-shows with automatic reminders and one-click rescheduling. If automatic card charges for no-shows are essential for you, Square Appointments supports them on paid plans.
Square offers a free plan and paid plans billed per location, and card processing fees apply to payments. Prices change, so check Square's pricing page for current numbers.
