we need an online agreement system for a doctor's office:
a google calender is shown on a website:
The patient goes to a website and wants to do an appointment. He clicks on the calendar:
There the free and blocked times of the doctor are displayed. The patient can choose from the free times and fill in time which.
The docto's office is informed automatically and the patient as well.
Important: The data of the other patient is only shown to the other doctors' office. The other patient only see blocked
Maybe: Only the function to log in and to change the date later
I only work with people I can talk to by phone (I'll call you - no worries about the call fee)
