E-Invoicing in Norway

Norway brought its B2B mandate forward from 2028 to January 2027. If you planned around the original date, you have lost a year of runway.

Talk to us about Norway
In short

E-invoicing in Norway requires domestic B2B invoices to be issued as structured electronic documents through the Peppol network, using EHF 3.0 (Peppol BIS Billing 3.0 / EN 16931). Norway introduces mandatory B2B e-invoicing from 1 January 2027, with mandatory e-invoice reception and digital bookkeeping following from 1 January 2030. The mandates were approved by the Stortinget in June 2026. The Ministry of Finance assignment letter of 16 March 2026 pulled the B2B obligation forward by a year, from 2028 to 2027. EHF 3.0 — Norway's Peppol-based national format, aligned with Peppol BIS Billing 3.0 and based on UBL under EN 16931 — is the proposed standard. Scope is expected to cover all businesses subject to accounting obligations in Norway, including foreign companies with a local presence under the Norwegian Bookkeeping Act. Whatever the local mechanism, the invoice still has to come out of your ERP correctly — and in our experience that is where projects actually succeed or fail. ROSTAN builds the integration into Oracle EBS and Fusion Receivables so compliance is generated from the invoice the business already raises.

What Norway requires

Norway introduces mandatory B2B e-invoicing from 1 January 2027, with mandatory e-invoice reception and digital bookkeeping following from 1 January 2030. The mandates were approved by the Stortinget in June 2026. The Ministry of Finance assignment letter of 16 March 2026 pulled the B2B obligation forward by a year, from 2028 to 2027.

What makes Norway different

The details that change the integration

The date moved forward, not back

Most mandates slip. Norway's went the other way — a March 2026 assignment letter pulled the B2B obligation from 2028 to 2027. Any plan built on the original date has a year less than it assumed.

EHF 3.0 is Peppol underneath

EHF is Norway's national format but it is aligned with Peppol BIS Billing 3.0 and built on UBL under EN 16931. If you already produce Peppol documents for Belgium, the gap is smaller than the different name suggests.

Foreign entities are in scope

Scope follows the Norwegian Bookkeeping Act rather than nationality, so foreign companies with a local presence and accounting obligations in Norway are expected to be covered too.

2030 is the second date

Mandatory e-invoice reception and digital bookkeeping follow from 1 January 2030. Designing only for the 2027 issuing obligation means revisiting the same integration later.

The portal is rarely the problem

Statutory e-invoicing is the single largest workload on our own Oracle service desk. These are the causes we see behind rejections, wherever the mandate is.

Tax or product master data that does not match what the schema expects — the most common single cause.
Party identifiers (VAT numbers, registration IDs, addresses) missing or formatted for a human rather than a validator.
A payload that validates in test and fails in production because a real invoice carries a case the sample never did.
No controlled retry path — a rejected invoice is not a valid invoice, and manual re-keying does not scale.
Nobody owning reconciliation: invoices issued in the ERP but never confirmed as accepted downstream.
The receiving side left out of scope, so supplier invoices arrive in a format Accounts Payable cannot process.
