Norway is moving from widespread voluntary e-invoicing to a mandatory B2B model.
From 1 January 2027, businesses subject to Norwegian bookkeeping obligations will enter the first phase of the new e-invoicing requirements. The change is particularly important for finance teams, multinational companies and businesses using ERP systems such as SAP, Oracle or Microsoft Dynamics.
And one point needs to be clear from the start: a PDF invoice attached to an email is not the same thing as a structured electronic invoice.
Norway’s e-invoicing model is designed around structured invoice data that can move directly between business systems and support automated processing.
When Does Mandatory E-Invoicing Start in Norway?
Norway is introducing the new requirements in two major phases.
1 January 2027: The B2B e-invoicing sending requirement begins for businesses covered by Norwegian bookkeeping rules.
1 January 2030: Businesses must use digital accounting systems capable of receiving and automatically processing electronic invoices.
This means companies should not treat 2030 as the real deadline. For accounts receivable, ERP and outbound invoicing teams, 2027 is the date that matters now.
Who Is Affected by Norway’s E-Invoicing Mandate?
The rules are linked to Norwegian bookkeeping obligations, rather than simply the location of a company’s headquarters.
Norwegian companies that fall under the Bookkeeping Act are therefore in scope. Foreign companies may also be affected when their Norwegian operations or registrations create bookkeeping obligations in Norway.
For international groups, one of the first steps should be identifying exactly which legal entities and invoice flows fall within the Norwegian requirements.
How Will E-Invoicing Work in Norway?
Norway already has a mature electronic invoicing infrastructure built around EHF, Peppol and electronic recipient registration.
Instead of sending invoice information as an unstructured document, businesses exchange structured invoice data that accounting and ERP systems can process automatically.
A typical process looks like this:
The supplier creates the invoice in its ERP or accounting system. The invoice is converted into the required structured format and transmitted through a Peppol-enabled service. Recipient information is identified electronically, and the invoice is delivered to the buyer’s connected financial system.
This reduces manual data entry and creates a much stronger foundation for automated accounts receivable and accounts payable processes.
What Are EHF, Peppol and ELMA?
These three terms will appear frequently when preparing for e-invoicing in Norway.
EHF stands for Elektronisk Handelsformat and is Norway’s established framework for structured electronic business documents.
Peppol provides the network and interoperability model used to exchange those documents between businesses.
ELMA is Norway’s electronic recipient register and plays an important role in identifying businesses that can receive electronic documents.
Detailed format requirements for the new mandate are being addressed through secondary regulations. However, EHF and Peppol already form the core of Norway’s existing e-invoicing infrastructure.
Is Your ERP Ready for Norway E-Invoicing?
For companies running SAP, Oracle, Microsoft Dynamics or another ERP platform, compliance is not simply an accounting question.
Finance and IT teams should check whether their systems can:
- Generate structured electronic invoices
- Support Norwegian invoice data requirements
- Connect to the Peppol network
- Identify electronic invoice recipients
- Validate invoice data before transmission
- Monitor invoice delivery and rejection statuses
- Prepare for automated inbound invoice processing
Waiting until the end of 2026 could turn what should be an integration project into a compliance deadline.
Preparing for Norway’s 2027 E-Invoicing Mandate
A good starting point is to map your Norwegian invoice flows.
Identify which entities are subject to Norwegian bookkeeping requirements, which customers can already receive electronic invoices, what formats your ERP currently generates and how your business connects to Peppol.
The deadline may be 1 January 2027, but the work begins much earlier.
For businesses operating across several European countries, Norway should also be considered as part of a broader e-invoicing strategy rather than another isolated country-specific integration.
