Google Calendar Integration

Google Calendar booking sync
never double-book again.

Two-way sync between your booking system and Google Calendar — new bookings appear on your calendar instantly, and existing events block those times from being booked.

Free to get started True two-way sync, not just export Per-staff calendar connections

Built for teams already living in Google Calendar

Your calendar, always up to date

No copy-pasting appointments between systems. Book once, and it's everywhere.

Two-way sync

New bookings are pushed to Google Calendar automatically, and busy time already on your Google Calendar blocks those slots from new bookings.

Real-time updates

Cancel or reschedule a booking and the change reflects on Google Calendar within moments — no manual clean-up.

Per-staff calendar connections

Each staff member connects their own Google account, so personal appointments outside work naturally block their booking availability too.

One source of truth

Stop checking two calendars to confirm you're free — your booking system and Google Calendar always agree.

Why teams connect Google Calendar

  • Staff keep using the calendar app they already check every day — no new habit to build.
  • A personal event on someone's Google Calendar automatically blocks that time from client bookings — no manual "block off" step.
  • Works alongside multiple staff members, each with their own connected calendar and independent schedule.
  • No spreadsheet or second system to keep in sync by hand.

Frequently asked questions

Is this a one-way export or a real two-way sync?

It's two-way — bookings push to Google Calendar, and existing Google Calendar events block those times from new bookings.

Can each staff member connect their own Google Calendar?

Yes, calendar connections are per staff member, so each person's own schedule and availability stay accurate.

What happens if I cancel a booking?

The corresponding Google Calendar event is removed automatically, and the slot reopens for new bookings.
