Norway’s parliament, the Stortinget, passed an amendment to the bokføringsloven (Bookkeeping Act) in June 2026 making B2B electronic invoicing mandatory from 1 January 2027 (VATupdate, 16 June 2026). Norway now completes the Nordic picture — while Sweden remains on the sidelines and Denmark has already laid its foundations.
Context: Scandinavia Moving at Three Different Speeds
The three Nordic neighbours have not advanced at the same pace on B2B e-invoicing.
Denmark. The region’s pioneer, Denmark introduced mandatory digital bookkeeping for companies above a turnover threshold through its bogføringsloven (Bookkeeping Act), with phased implementation running from 2024 through early 2026. The NemHandel platform — interoperable with Peppol — serves as the national reference infrastructure for electronic invoice exchange (Zone & Co).
Sweden. The picture is different: Sweden has required e-invoicing for public procurement (B2G) since 2019, but no B2B mandate has yet been voted into law. The Swedish government is studying the question; a decision is expected before the end of 2026.
Norway. With Prop. 44 L (2025-2026), the timeline is now set (EDICOM, 19 June 2026):
- 1 January 2027: electronic invoice issuance mandatory for all entities subject to bookkeeping obligations
- 1 January 2030: automated receipt and fully digital bookkeeping required
The mandated format is EHF 3.0 (Elektronisk Handelsformat), aligned with Peppol BIS Billing 3.0 and the European standard EN 16931 (RTC Suite). Transmission is exclusively through the Peppol network via certified Access Points. The ELMA registry, operated by the Agency for Public Management and eGovernment (DFO), acts as the national directory: before each send, the issuer must verify that the recipient is registered.
Exemptions: entities with annual turnover below NOK 50,000 are excluded, as are B2C transactions and cash sales (EDICOM).
Impact on ERP Systems and Finance/IT Teams
What Your Software Must Be Able to Do Before 1 January 2027
Three technical capabilities are required:
- Generate invoices in structured UBL format compliant with EHF 3.0 / Peppol BIS 3.0
- Transmit via a certified Peppol Access Point (native module or third-party connector)
- Verify that each recipient is registered in ELMA before sending
The situation varies depending on the ERP in use:
- Visma (Visma.net, eAccounting): native Peppol integration. For most customers, a configuration update is sufficient.
- Tripletex: Norwegian cloud solution with Peppol and ELMA support already active. Review company settings to confirm.
- Poweroffice Go: Peppol connector available. Validate based on your subscription plan.
- SAP S/4HANA / Microsoft Dynamics 365: require a third-party Access Point (Basware, Pagero, Comarch) or activation of an e-document module. Budget 1 to 3 months for the activation project.
The Real Timeline Is Tighter Than It Looks
The regulatory go-live is 1 January 2027, but the effective preparation window is closing quickly. The implementation chain includes: selecting or activating an Access Point, configuration, end-to-end testing with trading partners, and training accounts-payable teams. For an SME with a standard ERP, 3 to 4 months is a reasonable project estimate. For a mid-market company with multi-entity or multi-country flows, allow more.
Norwegian companies also operating in Denmark should consider unifying their Peppol infrastructure: the investment is shareable since both countries use the same interoperability network.
What to Watch For
Skatteetaten (the Norwegian Tax Administration) still needs to publish implementing regulations detailing archiving requirements, penalties, and exemption details. These are expected in Q3 2026: without them, technical preparation can proceed, but legal validation remains pending.
On the Swedish side, if Stockholm decides to join Oslo and Copenhagen before 2028, Nordic groups will need a unified Peppol infrastructure operational across all three markets. The shared network will ease the transition, but country-by-country configuration remains a distinct workstream.
