# Bookings in the calendar your team already uses

> Two-way Google Calendar and Outlook sync in your own booking system: busy time blocks availability and every booking lands in the right calendar.

A booking feature Timerise builds into custom booking systems its clients own. One fixed project price, typically $15,000 to $50,000, with this feature part of it. Last updated: 2026-10-20.

Your team lives in Google Calendar or Outlook, and the booking tool does not see it. We build two-way calendar sync into your booking system, so busy time blocks availability and every booking lands where people look.

What goes wrong without it:
- A private appointment in someone's calendar does not stop a customer from booking them at the same time.
- Ready-made sync is often one way, slow, or limited to one calendar per person.

How we build it, to the client's rules:
- Two-way sync: Busy time in the calendar blocks booking, and confirmed bookings appear in the calendar within seconds.
- Google and Microsoft: Google Workspace and Microsoft 365 calendars, each person connected with their own account.
- Meeting links: A Google Meet or Teams link added to the booking when the meeting is online.
- Time zones: Customers see times in their own zone, your team in theirs.

Compared with a SaaS tool:
- Direction. In a SaaS tool: Often one way, or one calendar per person. In your own system: Two-way, with as many calendars as each person needs.
- Speed. In a SaaS tool: Changes appear after minutes. In your own system: Push updates, so changes appear within seconds.

FAQ:
- Q: Does the system see everything in our calendars?
  A: Only what it needs: when each person is busy. It does not read the titles or details of private events.
- Q: What does this feature add to the price?
  A: It is part of the one fixed price for your system, and you see it in the quote before the build starts. Most projects cost $15,000 to $50,000 in total, paid once, with no subscription and no commission on bookings.
- Q: Can you add it to a system we already run?
  A: Yes. We build it into a new system or into the one you already run, with its own quote. When the feature has an Agent Skill, your own developers can also build it with the skill.
- Q: Who owns the code?
  A: You do. The code, the data and the documentation are handed over, and the system runs in your cloud account or on ours. Every project includes 3 years of support.
