If you run a small business and meet with clients or colleagues often, you're probably making appointments almost daily. Some people in larger organisations are lucky enough to have an assistant whose job is to prevent double-bookings and missed appointments. For everyone else, juggling that yourself (alongside everything else on your plate) is time-consuming, and rescheduling or cancelling is where it really gets messy.
This is where online appointment scheduling software is such a lifesaver. You share a link, your client picks a time that suits them, and the appointment lands in your calendar. No back-and-forth emails.
This post was first written back in 2010, and the scheduling world has changed a lot since then. A few of the programs I originally recommended have been bought out, renamed or taken in new directions, so I've rechecked everything and refreshed the list for 2026.
What Is Online Appointment Scheduling Software?
Online appointment scheduling software lets clients book times with you directly through a personal booking page or link, based on the availability you've set. It checks your calendar so you don't get double-booked, and most tools send automatic confirmations and reminders by email (and sometimes text).
How Online Appointment Schedulers Work
Most of them work in a very similar way:
- Connect your calendar and choose the days and times you're available.
- Set up your appointment types, such as a 15-minute chat, a 60-minute session or a paid consultation.
- Share your booking link by email, on your website or in your social media bio.
- Your client picks a time from the slots you're offering, and the booking is saved to your calendar automatically.
- Reminders go out so people remember to turn up.
That's it! Your appointment is booked and saved.
The Benefits of Online Appointment Scheduling
- You get time back. Think about what you could do with the hours you spend scheduling and rescheduling each month.
- Fewer no-shows. Automatic reminders mean people are far less likely to forget.
- Clients can book any time. Even at 10pm on a Sunday, when you're not at your desk.
- No more double-bookings. The software checks your calendar for you.
- A more professional first impression. A tidy booking page tells clients you're organised.
- You can get paid up front. Some tools let you take payment or a deposit when someone books.
What to Look For in Appointment Scheduling Software
Before you choose, think about what you actually need:
- Calendar sync. It should work with the calendar you already use (Google, Outlook or Apple).
- Different appointment types. Do you offer more than one kind of session or length?
- Payments. Do you want to take payment or deposits when people book?
- Reminders. Email is standard, but text reminders can really cut no-shows.
- Team scheduling. Do you have staff or a VA who also need to be bookable?
- Website fit. Can you embed the booking page on your own site?
- Cost. What does the free plan include, and when will you need to upgrade?
Online Appointment Scheduling Tools at a Glance
Tool | Best for | Free plan? | Takes payments? |
|---|---|---|---|
Calendly | Simple booking links for one-on-one calls | Yes (one appointment type) | On paid plans |
Google Calendar | People who already live in Google | Yes (one booking page on a personal account) | Paid Workspace plans, via Stripe |

Plans and limits change often, so check each pricing page before you commit. Last checked October 2026.
1. Calendly
Calendly is probably the best-known scheduling tool, and for good reason. It's simple to set up, connects to your calendar and lets people book through a clean link. The free plan gives you one appointment type and one connected calendar, with unlimited bookings.
Good for: coaches, consultants and freelancers who offer one main type of call.
Worth knowing: if you offer more than one type of appointment (say a free intro call and a paid session), you'll need a paid plan. Paid plans start at around US$10 a month per user when billed annually, and add things like unlimited appointment types and payment options.
2. Google Calendar Appointment Schedules
If you already use Google Calendar, you may have a booking page built in without realising. With a personal Google account you can create a booking page and accept unlimited appointments at no charge, and it automatically avoids clashes with your other events.
Good for: keeping things simple and free if you're already in the Google world.
Worth knowing: a personal account is limited to a single booking page. Extras like multiple booking pages and taking payments are part of paid Google plans.
3. Cal.com
Cal.com is often described as an alternative to Calendly, and its free plan (for one user) is more generous. It includes unlimited appointment types and calendar connections, and you can take payments through Stripe and PayPal.
Good for: anyone who needs several appointment types without paying, and who's comfortable with a slightly more technical tool.
Worth knowing: it has more settings than Calendly, so it can take a little longer to set up. Team features are on paid plans.
4. Square Appointments
Square Appointments is available in Australia and includes a free plan for solo providers, with online booking and automatic reminders. It's built into Square's payment system, so you can take payment at booking, require a deposit or charge a no-show fee.
Good for: service providers who want booking and payments in one place.
Worth knowing: the free plan is for one person only, and payments go through Square, so processing fees apply. Multiple staff calendars need a paid plan.
5. Setmore
Setmore offers a free plan for up to four users, which makes it a good fit for a small team. You get a booking page, reminders and a calendar for each person.
Good for: small teams, or a business owner plus a VA or assistant.
Worth knowing: the free plan has limits (including a cap on how many appointments you can take each month), and things like taking payments sit on the paid plans. Check the details before you build your whole business around it.
6. Acuity Scheduling
Acuity Scheduling is a full-featured scheduler owned by Squarespace. It handles multiple appointment types, intake forms, packages, payments, group classes and more, and it plugs neatly into a Squarespace website.
Good for: businesses that want a more powerful tool, particularly if they already use Squarespace.
Worth knowing: there's no permanent free plan, only a 7-day free trial. Paid plans start at around US$16 a month when billed annually.
For Salons, Beauty and Wellness Businesses
If you run a salon, barbershop, spa or similar business, a tool built specifically for your industry may suit you better than a general scheduler:
- Timely, which I used to list, is now focused on salon booking and payments.
- Booksy is built for beauty and barber professionals and includes booking, payments, reminders and a marketplace where local clients can find you. It offers a 14-day free trial.
- DaySmart Appointments offers scheduling for a range of industries and is available on a free trial.
What Happened to Genbook, Appointment Plus and Web-Appointments?
If you're looking for programs from my original list, here's where they are now:
- Genbook now redirects to Booksy, which focuses on beauty and barber businesses.
- Appointment Plus has been renamed DaySmart Appointments.
- Web-Appointments is still online, though its website still shows a 2020 copyright notice, so check carefully that it still suits you before signing up.
- Timely is still going but is now salon software.
How to Choose the Right Appointment Scheduler
- Offer one type of call and want it free? Calendly or Google Calendar.
- Need several appointment types for free? Cal.com.
- Want to take payments or deposits? Square Appointments, Cal.com or Acuity.
- Have a small team? Setmore.
- Want a powerful all-rounder (and don't mind paying)? Acuity.
- Run a salon or beauty business? Look at Booksy.
Most have a free plan or trial, so try one or two for a week before you decide.
Tips for Getting More Bookings and Fewer No-Shows
- Put your link where people will see it. Add it to your email signature, website, social bios and welcome emails.
- Keep your appointment types simple. Too many options can make people hesitate.
- Add buffers between appointments. A few minutes before and after protects you from back-to-back days.
- Turn on reminders. One a day or two before, and another closer to the time, works well.
- Ask for a deposit on higher-priced sessions. It makes people more likely to show up.
- Check your time zones. If you work with international clients, make sure the tool shows times in their local time zone.
- Include the booking link in your emails. A simple "Book a time with me here" at the end of a welcome sequence can turn readers into clients. I cover more on that in DELIVER: How To Use Email For Unstoppable Sales And Loyal Customers.
