How to let clients book appointments online

Online booking lets clients pick an open time that matches your real availability, without back-and-forth messages. Scheduling software connects to your calendar, shows the slots you choose, sends confirmations and reminders, and can take a payment or deposit at booking through a payment processor. The main choices are how many staff and services you book and whether you need payment up front.

Bottom line up frontby Bill Belcamino, founder of HelpCompare
Editorial assessment

Bottom line up front: How much does online appointment booking cost once the whole team is bookable?

It depends on the billing unit: Calendly is $10/mo per seat billed yearly, which the page puts at $100/mo for a team of 10, while Acuity Scheduling starts at $16/mo for 1 calendar, billed annually.

Calendly's free plan is limited to 1 event type, Acuity is trial only, and deposits add processing on top (Stripe 2.9% + 30¢, PayPal 3.49% + 49¢ on PayPal Checkout per transaction). The real money in booking is no-shows, not the subscription. Put an easy reschedule link in every reminder, because a client who can move a slot with a couple of taps usually will, while one who has to phone you often just doesn't turn up. For long or high-value services, take a deposit at booking, since having something at stake changes behaviour more than any reminder, and set a minimum notice time so nobody grabs a slot before you can prepare. Write the cancellation policy first, then price the plan that covers every person, room and service you'll book.

Frequently asked questions

What is the best appointment scheduling app for a small business?

Look for one that syncs with your calendars, handles your number of staff and services, and sends the reminders your clients read. We track 3 scheduling tools: Calendly, Acuity Scheduling and Cal.com. Compare them on those points and on the price for your full team.

Is there a free online booking system?

Of the 3 scheduling tools we track, Calendly and Cal.com list a free plan or free tier (limits are in the table above); Acuity Scheduling does not. Free plans are often limited to one calendar or one type of appointment, so check the limits against how you book.

How do I set up appointment reminders?

Check whether your scheduling tool can send automatic confirmations and reminders for each appointment type. Choose the channel your clients read, set the timing, and test it by booking yourself.

What should I look for in Calendly alternatives?

Compare calendar sync, pricing for your whole team, reminder channels, payment options and the client booking experience. The table above shows each tool's verified entry price and billing unit.

How we built this page

We start from the job, not the product. The phrasings people search for this job (for example “appointment scheduling app for small business”) come from our research into how small and mid-size teams describe it. Which software categories the job takes is our editorial judgment. Every tool, entry price, billing unit and date comes from HelpCompare’s open dataset, recorded from each vendor’s own pricing page; nothing is estimated, and where a vendor publishes no price we say so. We take no affiliate commissions and publish no scores of our own. See our methodology or download the data from Open Data.

Founder and author, HelpCompare

Engineer by training, operator by experience, marketer by choice. Bill spent eight and a half years as an engineer at HP, was COO of Auctiva (the number one third-party selling platform on eBay, past 200,000 users) and ran Google’s $70M/year search syndication partnership at Alot.com. Then he spent 13 years building his own web properties with his own money at stake. He has bought, trialled, integrated and cancelled more SaaS tools than he can count, and started HelpCompare because the real cost of switching tools is the part nobody covers.
