Slotly vs Square Appointments
Square Appointments is a solid choice if you already run Square for point-of-sale and in-person card payments — booking, checkout, and your register live in one account. Slotly is calendar-first and processor-agnostic: it focuses on the online booking experience, team routing, intake, and reminders, and connects to your existing Google or Outlook calendar rather than pulling you into one payments ecosystem. The right pick depends mostly on whether Square POS is already the center of your business.

Why choose Slotly
- Calendar-agnostic: two-way sync with both Google and Outlook, so mixed-calendar teams aren't pushed into one ecosystem
- Stronger team scheduling — round-robin, collective events, and routing forms for agencies, clinics, and multi-provider teams
- Per-provider and per-resource availability so you never book a room, chair, or specialist that isn't free
- Custom branding and a custom domain on the booking page, plus an open, self-hostable core for data control
- A 14-day free trial of all paid features, free for 14 days and cancellable anytime, then paid plans from $19/mo
Slotly trade-offs
- No integrated in-person POS or card-reader hardware — if you ring up retail sales at a counter, Square does that natively and Slotly does not
- Payments run through Stripe rather than Square, so businesses already standardized on Square processing would switch processors
- Newer brand with a smaller ecosystem than Square's established suite of business tools
Square Appointments strengths
- Tightly integrated with Square POS, card readers, and payouts — booking, checkout, and your register share one account
- Genuinely strong for in-person, walk-in-friendly businesses like salons, barbershops, and spas
- Free tier available, and pricing is approachable for solo operators and small teams
- Mature, widely-used platform with retail, payroll, and marketing tools in the same Square ecosystem
Square Appointments weaknesses
- Best value comes from committing to the Square payments ecosystem; you process card payments through Square
- Team routing, collective events, and qualification forms are more limited than purpose-built scheduling tools
- Calendar sync and branding are more constrained, and it leans toward in-person, Square-centric workflows rather than online-first or mixed Google/Outlook teams
How to migrate from Square Appointments
- Export your Square Appointments services with their durations, prices, staff assignments, and intake questions.
- Recreate each service as a Slotly event type, setting per-provider and per-resource availability where you have multiple staff, rooms, or chairs.
- Connect the same Google or Outlook calendar your team already uses so existing commitments immediately block availability.
- Connect Stripe to take deposits and payments, and turn on SMS + email reminders with one-tap reschedule to cut no-shows.
- Set your booking page slug, add your custom domain and branding, and rebuild any intake or qualification questions.
- Swap your Square booking links across your site, social profiles, and email signature, run both in parallel for a week, then retire Square Appointments once bookings flow cleanly.
If Square POS is already the heart of your business — you take card payments at a counter, run retail alongside services, and want booking in the same account — Square Appointments is the natural, well-integrated choice. If you're online-first, run a mixed Google/Outlook team, need round-robin and routing across multiple providers and rooms, or want custom branding and an open self-hostable core without committing to one payments ecosystem, Slotly will serve you better. Many salons and walk-in shops are happy on Square; agencies, clinics, consultants, and multi-provider service teams tend to get more from Slotly.

Is Slotly a good Square Appointments alternative?
Yes, especially if your business is online-first, runs a mixed Google/Outlook team, or needs stronger routing and per-resource scheduling. If your business revolves around in-person Square POS and a card reader at the counter, Square Appointments may still be the better fit because booking and checkout share one Square account.
Do I have to use Square's payments if I switch to Slotly?
No. Slotly takes deposits and payments through Stripe, so you're not tied to Square's processor. If you're already deeply invested in Square for retail checkout and payouts, factor a processor change into your decision.
Can Slotly handle a salon or spa with multiple staff and rooms?
Yes. Slotly models per-provider and per-resource availability, so it won't book a stylist, room, or chair that isn't free. Square Appointments handles per-staff scheduling well too; the difference is Slotly's resource rules, routing, and branding versus Square's integrated in-person POS.
Does Slotly work with the calendar my team already uses?
Yes. Slotly does two-way sync with both Google and Outlook, which is useful for teams that aren't standardized on a single ecosystem. Connect your existing calendar and your real commitments immediately block availability.
