SyncStay is an independent tool and is not affiliated with, endorsed by, or sponsored by Airbnb, Booking.com, or WhatsApp. All product names and trademarks belong to their respective owners.

Direct bookings break every calendar

Airbnb and Booking can sync to each other — but the moment a guest books by phone, WhatsApp or Instagram, you're updating everything by hand. One slip costs you money.

A friend reserves on WhatsApp

…and you have to block those dates on Airbnb, Booking and everywhere else by hand, hoping you don't forget one.

Guest books on Airbnb

…and now you scramble to block the same dates on Booking.com before someone else grabs them.

Miss one update

…and you've got a double booking, an angry guest, a refund, and a dented rating.

Conflict detection

Two guests, one night. You'll know fast.

Double bookings are what happen when nobody notices in time. Noticing is the part we're built around.

You don't have to check

We re-check every connected calendar every 15 minutes, around the clock. You find out because we looked — not because you happened to log in.

Every channel, against each other

Airbnb, Booking.com and the direct bookings you added yourself are all checked against one another — not just platform to platform.

Early enough to fix it

Finding out while the guest is still a message away means a phone call, a refund and an apology. Finding out at check-in means someone at the door and a one-star review.

Being straight with you: publishing your blocks out to the other platforms takes longer, because that runs on their refresh schedule rather than ours. Detection is the part we control — so that's the part we made fast.

Set it up once. Forget about double bookings.

Step 1

Connect your calendars

Paste your Airbnb and Booking.com calendar links — we walk you through it step by step. No technical setup.

Step 2

Add direct bookings in one tap

Friend booked by phone or WhatsApp? Add it once and SyncStay blocks those dates across your platforms.

Step 3

Everything stays in sync

Connected calendars refresh automatically, and any overlap between two real reservations is flagged as soon as we see it.

Built for small hosts, not hotels

The big tools start at €23–29/month and bury the one feature you need under pricing engines, websites and CRMs. SyncStay does one job, well.

Questions, answered

Yes — that's the whole point. Phone, WhatsApp, Instagram, a friend — add the booking once and SyncStay blocks those dates across your connected platforms.

Your connected calendars (Airbnb, Booking.com) refresh automatically every 15 minutes, and direct bookings you add are reflected right away. We're upfront: it's near-real-time, not millisecond instant — so we flag any conflict the moment we spot it.

No. If you can copy and paste a link, you can set up SyncStay. We walk you through connecting each platform.

Starter covers up to 2 properties, Plus up to 5, and Pro up to 10. SyncStay is built for small hosts — if you grow beyond 10, the larger channel managers are a better fit.

Yes. Every plan starts with a 30-day free trial. You'll add a card to start it — nothing is charged during the trial — and you can cancel any time from Settings. If you cancel, you keep access until the end of your period.
