# Synchronization

**Keep the calendars of your units in sync with other platforms, such as Airbnb, Booking.com and Google Calendar, so a stay can't be booked twice. Each unit's** _**Synchronization**_ **tab shows its imported and exported calendars.**

Also on this tab:

- _Sync Bookingmood unit_: link the calendars of two of your units, see [Main and sub units](https://www.bookingmood.com/en-US/docs/units/main-and-sub-units).
- _One-time import_: import bookings from a spreadsheet, see [Data import](https://www.bookingmood.com/en-US/docs/synchronization/data-import).
