Since May 18, 2022, electronic invoicing has been mandatory for all public procurement processes in Luxembourg. The transition was progressive, beginning in 2022 with large economic operators, followed by medium-sized entities in October 2022, and culminating in March 2023 when small enterprises were also required to comply. This rollout aligns with the European Directive 2014/55/EU and marks Luxembourg’s full adoption of structured electronic invoicing in the B2G (business-to-government) sector.
Luxembourg mandates the use of structured invoice formats such as UBL and UN/CEFACT CII, and transmission is generally facilitated through the Peppol network, an EU-recognized interoperability framework. As a certified Peppol Access Point, B2Brouter enables compliant e-invoice exchange with Luxembourg’s public sector, helping businesses adapt seamlessly to legal and technical standards.
