Common questions
01. Do clients need an account?
No. Clients book from the public pages and get a private link to view or cancel. Only staff sign in.
02. Can two people book the same time?
No. Booking recomputes availability on the server for that exact start, and a unique index on the host and start time stops a last-millisecond double booking.
03. What does Google Calendar add?
Each booking is created on the host's own calendar with a Meet link for virtual meetings, the host's busy time is taken out of the free times, and an event deleted in Google cancels the booking.
04. Can hours differ by type of meeting?
Yes. In per-category mode a category with its own schedule uses only that schedule; the others use the host's default hours.
