How do you stop double booking?
Direct answer: Keep one shared schedule, give each visit a length and an arrival window, and let customers choose only from open slots. Apex Flow Scheduler works from a single calendar and offers only windows that are free.
Why double booking happens
Two calendars, a text thread and a paper book that disagree. Double booking is the most repeated scheduling complaint in our question research.
What helps
One source of truth, buffers for travel, lead time and blackout dates, and a rule that a request is not a booking until your team confirms it.
In Apex Flow Scheduler
Arrival windows, lead time and blackout dates, and owner confirmation work today. The self-serve booking page that shows live availability is rolling out.

Status words: Working today means it runs on live business data now. Rolling out means it is built and being switched on. In development means it is not available to use yet.
