From PMS to Wi-Fi.
All from one source.

Maximum IT integration for your hotel — protect yourself from data silos, double entry, and OTA dependency with the all-in-one aobis One Stack.

aobis One Stack: The complete IT solution for your hotel

Fragmented systems, data silos, and OTA commissions cost hotels time and margin every day. Without a holistic IT strategy, your team stays stuck in vendor ping-pong.

With aobis One Stack — from server infrastructure to network & security to complete hotel software — you’re always one step ahead.

In the worst case, a single booking is transferred manually five times. OTA commissions of 15–25% eat into your margin.
And a simple data question can take days instead of seconds to answer via Excel reporting

Our goal: IT that simply works — today and as you grow.

One partner. One stack. One hotel that works.

aobis One Stack is the integrated hotel ecosystem of leading hospitality solutions and the
matching IT infrastructure — all from one source.

From check-in to housekeeping.

Guests check themselves in and unlock the door with their smartphone — no key cards, no front desk queue. Housekeeping marks rooms as clean in real time via app, and vouchers sell around the clock.

And the CRM brings it all together in one guest profile — pre-stay, on-stay, post-stay, documented in compliance with GDPR.
