- Denmark is set to implement major updates to its e-invoicing format with the introduction of OIOUBL 3, announced by Nemhandel on November 21, 2024, featuring mandatory invoice message responses and alignment with the European e-invoicing standard (EN 16931).
- Key components of the OIOUBL 3 Invoice Package include a Business Interoperability Specification covering various invoice types, distinct business and message-level responses, and a detailed migration plan from the current OIOUBL 2.1 format.
- The phased migration timeline includes the release of the final version on April 10, 2025, with voluntary support starting on May 15, 2025, mandatory support beginning on November 15, 2025, and the phasing out of OIOUBL 2.1 by May 15, 2026, all aimed at modernizing Denmark’s e-invoicing system and enhancing data interoperability.
