Running a hotel means managing multiple software systems at once, and each one plays a distinct role in daily operations. Your property management system handles reservations and billing, while your phone system manages guest calls and wake-up services. Housekeeping tools track room status, and point-of-sale systems process charges from the restaurant, spa, and other outlets.
When these systems operate in isolation, the result is operational friction. Staff end up entering the same data into multiple platforms, information gets lost as it moves between departments, and guests receive inconsistent service as a result. The solution lies in PMS integration, which connects all your hotel systems so they communicate automatically and share data in real time.
This guide examines 10 companies that provide reliable PMS integration solutions for hospitality properties, helping you identify the right partner for your hotel’s specific requirements.
What Is PMS Integration?
PMS integration is the process of connecting your property management system with the other software and tools your hotel relies on every day. When systems integrate properly, information entered in one place becomes available everywhere it is needed, eliminating redundant work and reducing the chance of errors.
Consider what happens when a guest checks in through your PMS. That single action can trigger automatic updates across every connected system. The phone system activates the room line and displays the guest’s name on caller ID. Voicemail gets enabled, and wake-up call settings become available. As the guest uses hotel services, billing charges from phone calls, minibar purchases, and restaurant meals automatically post to the folio without manual intervention.
Without integration, staff must manually transfer this information between systems, which wastes valuable time and creates opportunities for mistakes. With proper integration in place, data flows where it needs to go, operations run more smoothly, and guests receive consistent service across every touchpoint throughout their stay.
