Most hospitality app proposals demo a polished booking flow, then reveal during integration testing that it never actually synced with the property's PMS in real time, the exact gap that produces double bookings. Zethic scopes PMS and GDS integration as the core technical problem from day one.

Chances are one of these is true.
What you get from this work.
Our hospitality mobile app development services start with the property systems the app has to talk to, not a generic booking template. Each piece below can run standalone or as one connected build.
Scoped first, before any guest-facing screen gets designed.
PMS integration architectureGDS integrationReal-time inventory syncChannel manager connections
We scope PMS and GDS integration first, since getting this wrong produces an app that looks finished but doesn't reflect real inventory. When the property needs custom functionality beyond a standard integration, our custom application development services cover that layer.
Built directly against the confirmed PMS integration.
Hotel booking app developmentHotel reservation systemRate and availability displayMulti-property support
Hotel booking app development here is built directly against the confirmed PMS integration, so the reservation system a guest sees matches what the property actually has available, not a cached view.
One data source for guests and staff, not two systems.
Guest experience appHotel CRM integrationUnified guest historyIn-stay requests & loyalty
The guest experience app connects to the same hotel CRM the front desk already uses, so a guest's history is visible in one place. When the flow needs deeper research first, our user experience design services cover that discovery.
Built for real hardware conditions, not a stable demo.
Contactless check-inHotel management appOffline reliabilityStaff-facing tools
Contactless check-in gets built for the reliability a front desk actually needs, working through weak connectivity and hardware failures, not just a demo on a stable office network. Tools extend to staff, not just guests.
Intelligent Engineering, our team for the full-stack work behind every rollout.
Why teams pick us for this.
A company that designs booking screens before confirming PMS integration is building on an assumption. We confirm the architecture first, often on the same high-throughput stack behind our GoLang development services.
Our hospitality app development connects the guest experience app, loyalty features, and hotel CRM, so staff and guests see the same information.
Contactless check-in and other work get tested against weak connectivity and real hardware, not just a stable demo environment.
Post-launch support and PMS updates are part of the same scope, often part of a digital transformation services project for multi-property groups.
This is the discovery phase every hospitality app project starts with, and it is how our services, part of Zethic's broader AI and digital solutions, move to a launched system.
Talk to us{ 01 }· Week 1-3
We confirm the property management system and GDS connections the app needs, and validate real-time inventory sync before any screens get designed.
{ 02 }· Week 3-7
Hotel booking app development proceeds against the confirmed integration, so the reservation system reflects real availability from day one.
{ 03 }· Week 7-10
The guest experience app connects to the hotel CRM, and contactless check-in gets built and tested against real connectivity conditions.

The hotel management app deploys across properties as needed, with PMS updates and post-launch support as part of the same scope.
Questions, answered.
Cost depends on the property systems involved: a single-property booking app costs less than a multi-property build with full PMS, GDS, and CRM integration. Most projects are quoted after a short review of existing systems.
Both. Most work integrates with the PMS and GDS a property already uses, since replacing an established system is rarely the right call when the actual need is a better-connected app layer on top of it.
A single-property booking app with confirmed PMS integration usually runs seven to ten weeks. A multi-property build with full GDS and CRM integration typically runs twelve to sixteen weeks.
Yes, when scoped correctly. Contactless check-in needs to handle weak connectivity and hardware failures gracefully, which is why we test against those conditions rather than only a stable network.
Both. A hotel management app that only serves guests misses half the operational problem. Staff-facing tools get built against the same PMS and CRM data guests interact with, so nothing falls out of sync — both sit on the same foundation as our broader mobile app development services.
