- Denmark plans to replace its dual e-invoicing formats (OIOUBL and Peppol BIS) with one common standard, NemHandel BIS 4, based on Peppol.
- The reform aims to reduce complexity and costs, improve interoperability, and align Denmark more closely with EU requirements and future rules like ViDA.
- Most stakeholders support the change, but concerns remain about Danish-specific extensions, implementation costs, loss of OIOUBL features, and the need for a realistic transition period.
- The rollout will be gradual: technical work in 2026–2027, a release candidate and final version in 2028, and migration through 2028–2029, with full OIOUBL phase-out expected by mid-2029.
- Businesses and providers will need to support both formats during the transition and prepare systems for Peppol BIS 4 and Danish extensions.
