Key Milestones and Implications for Businesses
Denmark is gearing up for a significant transformation in its e-Invoicing landscape. The Danish Business Authority recently unveiled the OIOUBL 3.0 invoice package as a “release candidate,” introducing an array of updates poised to redefine electronic invoicing standards across the nation. Slated for final release on April 10, 2025, OIOUBL 3.0 will join Peppol BIS 3.0 as one of Denmark’s two national e-Invoicing standards.
This updated framework outlines enhanced specifications for invoices, credit notes, and invoice response messages. Among the notable innovations is the introduction of distinct processes for handling invoice responses. Businesses will now need to support two-way communication, differentiating between technical confirmations (acknowledging receipt) and content-related acknowledgments (validating invoice details).
Critical Dates for Compliance
To ensure a smooth transition, the Danish Business Authority has provided a detailed implementation roadmap:
- Release Candidate Availability: Development and testing can begin immediately.
- Final Release: April 10, 2025.
- Mandatory Compliance: OIOUBL 3.0 becomes obligatory starting November 15, 2025.
- OIOUBL 2.1 Deprecation: Support for the current version ends on May 15, 2026.
What This Means for Your Business
The shift to OIOUBL 3.0 emphasizes Denmark’s commitment to efficient, transparent, and robust e-Invoicing practices. To remain compliant, businesses must align their invoicing systems to support the updated format and ensure they are prepared for mandatory implementation. Proactive steps now will mitigate potential disruptions and position companies for a seamless transition.
