Product · Integrations
It connects to what you already run.
The PMS as a module: credentials in a vault, guest-category mapping per hotel and a connection test from the dashboard. Everything else comes in through the API, the webhooks or the MCP server.

Frequently asked questions
Which PMSs are available?
OPERA Cloud (OHIP) today. Mews and Cloudbeds aren't available yet; write to us if your chain runs them.
What data does Mesatto read from the PMS?
When you look a guest up by room number and last name: name, email, room, arrival and departure dates, guest category, number of adults and children, membership if any, and the PMS reservation and profile numbers. Mesatto doesn't write to the PMS or post charges to the folio.
What happens if the PMS doesn't respond?
The reservation doesn't depend on it: each seating's capacity lives in Mesatto. The lookup shows the error and the concierge enters room, category and nights by hand, as in a hotel without a PMS.
Does it work without a PMS?
Yes. Room, guest category and nights are entered by hand once per reservation.
Does it connect to the point of sale (POS)?
No. Mesatto doesn't integrate with the POS. Each reservation stores the room and the price for its guest category.
How does the charge reach the room account?
Mesatto doesn't post charges to the PMS. The front desk downloads the day's reservations in Excel, with room, price and whether the guest showed up, and posts them to the account.
Can I send the emails from my own domain?
On Enterprise, with your own SMTP per brand.
What if my integration isn't on the list?
The public API and the webhooks cover availability, reservations and events; almost any system connects through them.
