Do you know of any client appointment scheduling software that has a decent free plan?

Super simple to use with time zones and your availability. Integrates well with calendar.

I use Calendly too. Love the time zone support :)

Avoid the annoying email back-and-forth, and let people choose from the times you have available.

Bitrix24 CRM is free and unlimited for appointment scheduling. See https://www.bitrix24.com/uses/fr... and https://www.bitrix24.com/uses/fr... for online PayPal support.

Mixmax Scheduling Assistant is a Calendly alternative that I've used earlier. Works pretty well in terms of showing time zones and availability and has a good calendar integration.

10to8, without doubt, has the most generous Free Forever Plan on the market, and it really is free forever. You get 100 appointments a month with two logins, you can send out both email and SMS reminders, set up 2-way calendar sync and integrate with over 1,500 apps via Zapier. 10to8 is very easy to set up, and if you get stuck somewhere, you can contact support anytime online. No other software offers this many features on the free version and if they do, it's usually just a trial, not an actual Free Forever Plan.

I really like it because it's easy to setup and free plan has customer reminders,so my customers don't miss their appointments.
