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.

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 2 scheduling tools: Calendly and Acuity Scheduling. Compare them on those points and on the price for your full team.

Is there a free online booking system?

Of the 2 scheduling tools we track, Calendly lists 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.
