Client booking system

Does anyone use a client online booking system? ie the client books the day and time in our calendar? I am looking for one tht integrates with Max and can also sync with our Google calendar. Thanks :slight_smile:

I use and really like AppointmentCore.

It has a very tight direct integration with Max Classic.
Feel free to book/cancel using my calendar to see how it works.

The other main system we have client using is Calendly.
