Connect Cal.com to the calendars your team actually uses and create a booking type with buffers, time-zone handling, and cancellation rules. Have a person in another time zone book and reschedule, then inspect both calendars and notification emails.
Double bookings and privacy leaks can outweigh a polished booking page. Test an unavailable slot, a canceled meeting, and account access boundaries. Adopt it when the full scheduling lifecycle works for host and guest.
