GMS. Modern guest journeys for existing hotel infrastructure.
GMS digitises the entire guest journey — from pre-arrival registration and digital check-in to mobile room keys and instant feedback — while integrating seamlessly with legacy Property Management Systems. MKL Hospitality Group, the first hotel group running it, reports 80% shorter front-desk queues.

02 / How it works
GMS in 6 steps.
An illustrated walkthrough with no sound. Each step is also written out here.
- 1
The reservation arrives from your PMS
GMS reads each booking from the property management system the hotel already runs. Nothing is replaced.
- 2
The guest registers before arriving
A link goes out ahead of the stay. Details and ID are submitted from the guest's own phone.
- 3
Check-in on a phone or the lobby kiosk
The guest confirms what they already submitted, with no form to fill at the desk.
- 4
The room key is on the phone
Once check-in clears, the phone opens the door.
- 5
Staff see every arrival and every task
One dashboard shows who has registered, who is checked in and what still needs doing, across every property.
- 6
Feedback comes back from the guest's phone
A short satisfaction survey, answered on the same phone the guest checked in with.
03 / How it is built
