Works with all three major platforms
The hidden cost of one platform
Most hosts stay on one platform.
Most hosts leave money behind.
Every platform has its own audience. Airbnb guests book differently than Booking.com guests. VRBO attracts families planning months ahead. If you're only on one, you're invisible to the others.
GuestFlow removes that risk entirely.

Everything in one view
Your three calendars, finally in one place.
GuestFlow uses your platform's built-in calendar link — no expensive API connection needed. Each platform shares its calendar as a simple web address. GuestFlow reads all three and merges them into one clear dashboard. These platforms use different date displays, so cross-platform updating can be highly confusing — with GuestFlow it's easy and automatic, syncing every 30 minutes or by manual trigger.

Every reservation from every platform, in one table. Colour-coded badges and the mini calendar give you the full picture at a glance.
How calendar sync works
Your calendars stay in sync. You stay in control.
When a booking comes in on any platform, GuestFlow updates its calendar straight away. The other platforms then fetch that update on their own schedule — usually within minutes to an hour.
That's where the traffic light system comes in.
Green — all clear
Platform has fetched your latest calendar. Dates are blocked.
Red — waiting for calendar fetch by platform
Sync hasn't completed. Either wait or log in to that platform and click the calendar refresh arrow before accepting.
Set up in under 5 minutes
No technical knowledge required.
