Double booking
Two guests show up on the same day. Refunds, bad reviews, and hours lost managing the fallout.
Calendar sync for rentals, guest houses and hotels
Airbnb, Booking.com, Expedia: one calendar, zero double bookings.
iCalSync merges your booking platforms and calendars into one planning, closes the dates everywhere as soon as a booking arrives, and warns you before a conflict costs you a guest. And now: your own booking website, without commission.

The cost of chaos
A poorly synced calendar always ends up costing you
Three platforms, three calendars, one apartment — and the risk of accepting the same date twice.
Clashing meetings
A Zoom call scheduled during a check-in, or two client meetings at the same time because no one has the full picture.
Manual updates
Copy-pasting dates from one platform to another, every day, hoping nothing slips through.
Under the hood
A dashboard that speaks in signals, not spreadsheets

New · Your booking website
Take direct bookings, without commission
Your guests search, choose a room and send a request, on the dates free on every platform. You accept it in iCalSync: the dates close on Airbnb, Booking.com and the others at once. No payment online: you confirm and get paid your usual way.
Hosted by iCalSyncyourname.icalsync.com, ready in a few minutes, nothing to install.
On your WordPressThe iCalSync Hotel extension adds the search and the rooms to your own site.
- Room search: arrival, departure, guests
- A page per room: photos, formulas, amenities, reviews, map
- Requests validated by you, confirmation e-mailed to the guest
- Included in the Properties plan
Hotelbeds too
Hotelbeds has no iCal link. iCalSync reads its e-mails.
Hotelbeds sends its bookings to guest houses and hotels by e-mail only. Forward them to iCalSync: each booking lands in the right room and blocks your other platforms, with no copying by hand.
Bookings in the right room
New bookings, changes and cancellations from Hotelbeds go into the planning by themselves, in a free room of the type sold.
Every other platform blocked
The stay goes out in your export links: Airbnb, Booking.com and Expedia close those dates on their own.
Know when to close Hotelbeds
A "fully booked" alert as soon as no room is left on a night, and an Excel export of every Hotelbeds booking with its reference.
Compatible booking sites
Every booking site that gives an iCal link works with iCalSync
Paste the iCal link of each platform: iCalSync merges them, then gives you one link per room to paste back on each platform. Here are the ones hosts connect most.
Booking platforms — iCal link
- Airbnb
- Booking.com
- Vrbo
- Abritel
- FeWo-direkt
- Expedia
- Agoda
- Holidu
- Atraveo
- Hipcamp
- Houfy

Your own website
- Hosted websiteyourname.icalsync.com

And any other site
Any booking system that offers an "iCal", "ICS" or "Export calendar" link (ending in .ics or starting with webcal://) can be connected.
Where the iCal link is found depends on each platform, and some keep it for certain property types (Agoda: homes and apartments). Names and brands belong to their owners.

Frequently asked
Questions hosts ask before starting
How do I sync my Airbnb calendar with Booking.com?
Paste each platform's iCal export link into iCalSync. Every calendar is imported, merged, and exported as one master calendar you republish on each platform.
Can I sync Hotelbeds bookings even though Hotelbeds has no iCal link?
Yes. iCalSync reads the booking e-mails Hotelbeds sends (new bookings, changes, cancellations), puts each one in the right room and blocks those dates on Airbnb, Booking.com and the others. It also alerts you when your property is fully booked, so you know when to close Hotelbeds in its Partner Portal.
Which booking sites work with iCalSync?
Every site that gives an iCal link: Airbnb, Booking.com, Vrbo (Abritel, FeWo-direkt), Expedia, Agoda, Holidu, Atraveo, Hipcamp, Houfy and many more. Hotelbeds, which has no iCal link, is read from its booking e-mails.
Can I take bookings on my own website?
Yes, in two ways: a booking website hosted by iCalSync at yourname.icalsync.com (nothing to install), or the iCalSync Hotel extension on your own WordPress site. Guests search, choose a room and send a request on the dates free on every platform; each request you accept closes those dates on Airbnb, Booking.com and the others. No commission: it is included in the Properties plan.
Does iCalSync work with Google Calendar and Outlook?
Yes. Paste the iCal link of your Google Calendar or Outlook calendar (Teams meetings included). Zoom meetings show up through the calendar they are added to.
How often are calendars synced?
For subscribers, iCalSync checks every connected calendar every minute (once a day during the free trial) and re-runs double-booking detection on every update. Airbnb, Booking.com and Vrbo then refresh on their own schedule (often every 1 to 3 hours).
Can I cancel anytime?
Yes. Cancel from your account in one click: you keep everything until the end of the period already paid.
Is my booking data secure?
Traffic runs over HTTPS, your export links are secret, and you stay in full control of which sources are connected to each calendar.
