Plugs straight into the hotel-tech stack you already run
Three steps. No spreadsheets.
GIMSI replaces the scattered tools and manual copy-paste with one guided flow your whole front office can follow.

Confirmed in GIMSI, booked in Apaleo.

Group management deserves the same API that powers your PMS.
GIMSI lives inside apaleo One in 11 places. Here's why we built it that way:
API-first design
apaleo's OpenAPI exposes folio state, reservations, payment events and multi-property isolation on a single surface. That's what lets HoTechOlution apps embed into apaleo One in real time — not as nightly batch syncs.
Real-time webhooks
apaleo Pay and reservation webhooks fire the moment something happens. Cases close in seconds; data stays in sync — not in tomorrow morning's reconciliation.
Multi-property by design
Every product respects per-property configuration: rules, exclusions, mappings and grace periods are independent. A 3-hotel group and a 30-hotel chain configure the same way.
EU-hosted, GDPR by design
Vienna-based, EU-hosted, built by a Geprüfter Datenschutzexperte. Same legal jurisdiction as our DACH hotel customers. No US sub-processors in the request path.
Proven across real hotel operations.
Simple pricing, whatever your size.
Every plan includes the certified Apaleo integration and a 30-day free trial. No credit card required.
