Connected to your PMS

Integrations

InnSync runs on top of your PMS — in sync, never in its place.

The ecosystem

How everything connects

The booking is born in a sales channel, lives in your PMS, and the guest is served on WhatsApp. InnSync keeps every end in sync — you don't switch systems.

Where the booking is born
Sales channels
AirbnbAirbnb
Booking.comBooking.com
Expedia

Bookings from these channels arrive through your PMS — InnSync doesn't access them directly.

Everything goes out through the company's number, on Meta's official WhatsApp.

Direct integrations

The right channel for each part of the operation

Your data sources (PMS) and your guest channel, each connected over a native API — no middlemen, no polling.

On another PMS — or no PMS at all?

InnSync is built to run on top of any PMS — or without one. Tell us which system you use: every new integration is built with the first partners on that system.

Channels that arrive through your PMS

Airbnb, Booking.com and Expedia

Bookings and messages from these channels flow through the Stays integration. InnSync receives the data from Stays — it doesn't access these channels directly.

If your Stays is connected to these channels, InnSync already sees the bookings that come in through them.
