If you advertise a property on several platforms, its availability should match on all of them. Syncing helps prevent conflicts. Understand what it transmits and check how it actually works after a change.
1. Decide where to manage availability
Before connecting Airbnb, Booking.com or a direct booking site, identify which calendar you will use as your reference. Record where to block your personal stays, where to change stay rules and who can edit each listing.
Uncoordinated changes in several tools become hard to trace. A night may be unavailable because of a booking, a manual block or an availability setting. Anyone managing the property needs to identify the reason before reopening that night.
2. Understand the limits of an iCal link
Airbnb lets you import and export calendars to link availability across platforms. Its guidance says imported calendars refresh automatically every three hours and can also be refreshed manually. This method therefore does not update availability instantly.
Airbnb also notes that certain blocks on an external calendar, including those for preparation time or advance notice, may not carry over to Airbnb. Check the settings on each channel. Linking calendars does not prove that all booking conditions match.
This describes iCal syncing as documented by Airbnb. Property management software may offer other connections that work differently. For a connected tool, check its documentation and the settings actually enabled on your account.
3. Check a change from start to finish
Plan a check appropriate for your tool, without accepting a fictitious booking or taking payment. Record which date you changed in the reference system, the time you changed it and what then appears on other channels. Where it is permitted and safe for existing bookings, also check that removing a block reopens the date.
- Does each connection point to the right property?
- Do the dates and the number of nights match?
- Are preparation days accounted for?
- Are personal stays blocked on the relevant channels?
- Does the observed delay match the tool’s stated refresh interval?
- Does someone know how to handle an alert or a lost connection?
Keep a dated record of the result. Repeat the relevant checks after switching tools, changing a listing or reconnecting an account. A previous test may no longer cover the current configuration.
4. Include direct bookings in the same process
A booking button on your website should use the same availability system as your listings. Check that the page draws from the system that actually manages the property’s dates. Then verify the entire booking journey and the effects of a real booking in a test arrangement agreed with your provider.
Baytt uses Hospitable to display availability on its booking pages. A widget loading or a quote appearing does not confirm that payment and syncing work after a booking is confirmed. Verify those steps in the account configuration rather than assuming they work because you can see the calendar.
5. Plan what to do if calendars disagree
If two channels show different availability, start by checking confirmed bookings and the reason for any blocked dates. Reopening everything to “start from scratch” could put an occupied period back on sale. Record the problem, protect the affected dates according to your tool’s procedure and contact support if necessary.
Reliable availability depends as much on these working practices as on the technical connection. For an owner who uses the apartment when returning to France, personal dates should follow the same process. Read about Mohamed in Saint-Ouen and our approach to managing stays.
