Koalendar

Koalendar gives away the thing most booking tools meter, which is the number of appointments, and puts its paid features around payments, reminders and team routing instead. Two calendar syncs and an embeddable booking page come at no cost with no time limit. Paying adds Stripe checkout at the point of booking, custom reminders and the removal of Koalendar's branding. It is a booking link rather than a practice management system, and anybody wanting intake forms and client records will outgrow it.

Free forever, with no time limit, covers unlimited bookings and scheduling links, two calendar syncs, video conferencing, more than thirty languages and embedding on your own site. Pro is $6.99 a seat a month on annual billing and adds unlimited syncs, Stripe and Apple Pay at the point of booking, custom email and SMS reminders, round robin and collective scheduling, and removal of the branding. A seven-day trial runs without a card. A Teams tier covers ten seats and up.

Somebody who books a lot of calls and does not want the count to decide their bill, particularly a coach or consultant whose free-plan usage would be throttled elsewhere. Embedding on your own site is included at no cost. Anybody needing intake forms, client notes and a record of past sessions is describing practice management software rather than a booking link.
