Hotels and food service businesses bill a wide range of short-term, often spontaneous services every day—from an overnight stay to a restaurant visit. In doing so, dynamic pricing, bundled services, and high transaction volumes meet the structured requirements of EN 16931. In practice, this leads to concrete implementation challenges: service bundles such as packages or add-on offerings are difficult to break down into clear line items, while systems running in parallel—such as point-of-sale, PMS, and inventory management—do not allow for end-to-end data flows. On top of this come high-volume transactions involving small amounts and instant billing, which have to be coordinated alongside structured invoices to business customers. Complex billing routes via corporate customers, travel agencies, or platforms, as well as differing tax and levy logic, add further requirements.

At the “Hospitality & Food Service” Industry Center, businesses work together with the industry association and application developers to address these challenges systematically. The starting point is concrete workflows such as reservations or corporate billing, from which typical challenges are derived. These feed into a structured catalog of requirements that serves as the basis for concrete implementation recommendations. Companies that take part contribute their questions directly. At the same time, practical solution approaches are developed for the entire sector, supporting the rollout of e-invoicing in day-to-day operations.
