Most hotel groups run their property operations in a separate PMS and then re-key revenue, city ledger and F&B costs into Business Central by hand at month end. This extension closes that gap by bringing the front desk and the general ledger into one system.

Hospitality & Hotel Management is a custom AL extension that ECOSIRE builds, installs and supports on your Dynamics 365 Business Central tenant. It is delivered as a per-tenant extension (published to your environment, not a generic AppSource download), so every table, page and posting routine is shaped to your room types, rate plans, outlets and chart of accounts.

The extension adds room and rate-plan master data, a reservation and availability engine, and a guest folio that posts room charges, taxes, city/tourism levies and outlet charges directly through Business Central's standard sales and G/L posting — no parallel ledger, no nightly export. Folio settlement creates posted sales invoices and reconciles against your existing payment methods and bank accounts.

Food-and-beverage cost control reuses Business Central's item, BOM and inventory engine: recipes are costed against live purchase prices, outlet POS sales decrement stock, and theoretical-vs-actual variance reporting flows into standard analysis views. A night-audit routine (run on a job queue schedule) rolls the business date, posts room and tax charges, and produces occupancy, ADR and RevPAR reporting.

External systems connect through the Business Central REST/OData v4 API, with an event-subscriber-based hook for OTA/channel-manager inventory and rate sync. Because the logic lives in AL using event subscribers and table/page extensions, it survives Microsoft's monthly updates and stays compatible with the Power Platform and Dataverse for dashboards and guest portals.

You receive scoped permission sets, a documented data model, and a support relationship — not a black box.
