Sync matters because most businesses accumulate calendars without meaning to. The office diary, the owner's phone, a booking tool, a shared team calendar. Each additional unsynced calendar is a new opportunity to promise the same slot twice, and the person who finds out is always the customer.
Two directions are worth distinguishing. Reading availability out means a booking system knows when you are genuinely free, including your dentist appointment and your kid's sports day. Writing bookings in means a confirmed job lands in the calendar you actually look at. A setup that does one but not the other usually still produces collisions.
Sync is also where lag causes problems. Near real time is fine. Every fifteen minutes is a window in which two people can claim the same slot. This is one reason Clerkzo treats website enquiries as booking requests with the details attached, delivered instantly by email, webhook or Telegram, so a human confirms against live availability rather than a machine writing blind into a calendar.
