Free Appointment Scheduling Software: What You Actually Get
What free appointment scheduling plans include and where they stop: Google Calendar, Calendly, Square Appointments and SimplyBook.me compared on free tiers.
Free plans are a good way to find out whether online booking suits your business, but each one stops somewhere. This article lists what four free options include, based on each vendor's own pages as checked on 20 September 2026, so you can see where the ceiling is before you build on one. We haven't tested them hands-on.
This article is part of our guide to choosing appointment scheduling software.
What each free option includes
| What's free | Where it stops | |
|---|---|---|
| Google Calendar appointment schedules | A booking page linked to your calendar, with availability rules, buffer time, daily limits and up to five reminders | Needs a personal Google Account or Workspace account, some features need Workspace or Google One, and schedules can only be created on a computer |
| Calendly Free | One event type, one calendar connection, one-to-one scheduling, a customisable booking page | Unlimited event types, multiple calendars, automations and payments are on paid plans |
| Square Appointments Free | Designed for solo professionals; online booking site and integrations; unlimited staff calendars listed | Cancellation policy and no-show fees, multi-staff appointment booking and waitlists are on higher plans; processing fees apply |
| SimplyBook.me Free | Up to 50 bookings a month, one feature and one provider | More bookings, features and providers need a higher tier |
Which limits matter to you
- Several types of appointment? Calendly's free plan has one event type. Google Calendar and SimplyBook.me may fit better, so check each.
- More than 50 bookings a month? SimplyBook.me's free plan caps at 50.
- Take payments or deposits? These sit on paid plans for Calendly and higher plans for Square. Google Calendar mentions connecting Stripe.
- Several staff? Check per-provider or per-seat limits.
- Working from a phone? Google's help page says schedules can't be created in the mobile Calendar app.
How to test a free plan properly
- Enter your real working hours, days off and buffer times.
- Book a test appointment yourself on a phone, all the way to the confirmation.
- Check that it appears in your calendar and that reminders arrive.
- Estimate a busy month's bookings against the limit.
- Find out what the next tier costs, so an upgrade is not a surprise.
Use the online booking setup checklist for the details.
When to pay
Upgrade when the limit costs you more than the plan: when you're turning away bookings, chasing no-shows by hand or copying details between systems. See how to reduce no-shows and Calendly vs Square Appointments vs SimplyBook.me.
Frequently asked questions
Is free scheduling software good enough for a small business?
For a sole trader with simple availability, often yes. Free plans tend to limit the number of appointment types, calendars, bookings or providers, so check that your real volume fits before you send customers to it.
What is the catch with free plans?
The limits. Each vendor's free plan caps something, such as event types, calendar connections or bookings a month, and the features you might want most, like payments and deposits, are usually on paid tiers.
Can I switch later?
Usually you'd set up the new tool and move your booking link. Ask what you can export, and tell customers if the link changes. We haven't tested migrations.
