Missed calls, double bookings, and no-shows cost you more than any monthly software bill ever will. Good scheduling software only shows the times you’re actually free, puts the appointment straight on your calendar, sends reminders, and — when you need it — collects payment before the customer shows up.
Different businesses need a different version of that system. A consultant booking video calls doesn’t need the same tool as a salon juggling several workers, rooms, and services.
The short answer
- Choose Calendly for simple meetings, consultations, and video calls.
- Choose Square Appointments when in-person services and payments belong in one system.
- Choose Acuity Scheduling for a polished client-booking flow with forms, packages, and more service detail.
- Choose SimplyBook.me when you need many industry-specific booking features and want to assemble them carefully.

Calendly
Best for calls, consultations, and straightforward meetings
Calendly’s dead simple: connect your calendar, set when you’re free, and share a booking link. It adds video-call details automatically and won’t let anyone book a time you’re already taken.
The free plan gives you one event type and one connected calendar. Standard runs $10 per seat a month paid yearly, and adds unlimited event types, multiple calendars, reminders, and Stripe or PayPal. Plenty for most solo professionals.
Square Appointments
Best for in-person services that also take payments
Square Appointments ties online booking into the broader Square payment system. That’s a real simplification if you’re a barber, beauty pro, trainer, repair shop, or other local business that wants bookings, customer records, and checkout all speaking the same language.
Square offers a free Appointments plan for a single location. Before you move everything over, compare the cost of additional locations, staff features, cancellation protection, reminders, and processing.
Acuity Scheduling
Best for a richer client intake and service experience
Acuity’s built for appointments that need more than just a time slot. You can collect intake info, offer classes or packages, run different calendars, and take payments. It’s owned by Squarespace, but works fine with other websites too.
Acuity gives you a free trial, then requires a paid plan. Check how many calendars, text reminders, gift certificates, packages, and subscription features each tier actually includes — those details matter more than the plan’s name.
SimplyBook.me
Best for configurable industry-specific booking
SimplyBook.me treats scheduling as a menu of features you switch on: payments, classes, memberships, waiting lists, intake forms, loyalty tools, and more. That flexibility can fit an unusual workflow without forcing you into a custom build.
The free plan’s fine for testing, but caps bookings and features. Before you pay, list the exact features you need and make sure one tier actually covers all of them — a cheap tier full of surprise limits isn’t really a bargain.
Set the rules before sharing your link
Software can’t protect time you never defined. Set a minimum notice period, gaps between appointments, a daily cap, a cancellation window, and exactly what info you need from a new customer. Then test the whole booking flow yourself, on your phone.
If no-shows cost you real money, collect full payment or a reasonable deposit upfront. Put the cancellation rule right next to the payment, not in a surprise email afterward. Then send one genuinely useful reminder with the time, location or call link, what to prepare, and how to reschedule.
How we evaluated these tools
We went through each product’s official pricing, feature, and help pages, comparing four distinct jobs: booking professional meetings, running in-person services with payments, collecting detailed client info, and configuring specialized booking features. We didn’t run hands-on reliability tests.
Frequently asked questions
What is appointment scheduling software?
It’s a booking page tied to your working calendar. A customer picks an open time, the system records it, and can send confirmations, reminders, forms, or payment requests on its own.
Should customers pay when they book?
Worth considering upfront if the time slot is hard to resell, no-shows are common, or you need to prep materials in advance. A free consultation might not need payment, but it still benefits from a clear cancellation rule.
Can I use Google Calendar by itself?
Sure, if you’re only booking a handful of appointments and the back-and-forth emails aren’t a burden yet. Scheduling software earns its keep once it starts preventing conflicts, cutting repeated messages, reducing no-shows, or collecting information consistently.
