System type · PMS
The PMS stays. Recognition sits under the stack.
The PMS guest card is not one person across the house. Recognition sits under the stack, so a switch does not rebuild the guest.
Problem
The card is not the house record.
Reservations live in the PMS, so teams treat its guest card as the person. That card knows what the property system was told. It does not know the outlet charge, the spa booking, or the stay that arrived on another address.
Outcome
The PMS stays.
The property system stays the system of reservation. A switch becomes a new feed, not a rebuild of the person. Outlet and booking fragments resolve to the same guest.
How Casa fits
One feed among others.
Casa Layer reads the PMS as one feed among others and reconciles the fragments into one Master Profile per real guest. The record sits under the stack. You decide what Casa Layer can do in each system, and you can revoke it. Every connection live today reads only.
Beside the property system




Guest Lookup reads the resolved guest beside the PMS. It is not a property-system screen. The guest in these shots is sample data, not a customer.
