Open Doors supports four calendar types so you can model exactly how your team takes appointments.
| Type | Best for |
|---|---|
| Personal | A single person taking 1:1 bookings. |
| Round-robin | Multiple team members where the next available person gets the booking. |
| Collective | Bookings that need two or more team members on the call at once. |
| Class | Group sessions with a fixed time and a max number of attendees. |
