E-Invoicing in Norway: A Practical Guide for All Businesses
Norway is one of Europe’s pioneers in adopting electronic invoicing, especially in public procurement. With well-established infrastructure and legal frameworks, e-invoicing has become the standard for B2G operations and is increasingly adopted in B2B environments as well.
With our e-compliance experience in more than 30 countries, the Melasoft SAP Add-On offers a simple, reliable, and fully compliant solution tailored to your company’s needs. It ensures smooth e-invoicing in Norway.
Legal Requirements:
Who Must Use E-Invoicing?
If you send invoices to public sector entities in Norway, you must use e-invoicing.
-
From 1 July 2012, suppliers to central government agencies were required to send electronic invoices.
-
From 2 April 2019, this requirement extended to all public sector bodies, including municipalities and regional authorities.
-
E-invoices must follow the EHF format (based on PEPPOL BIS Billing 3.0).
-
For B2B, e-invoicing is currently voluntary, but under review by the Norwegian government. A working group was formed on 16 January 2025 to assess future mandates.

PEPPOL Network: The Backbone of Norwegian E-Invoicing
Norway uses the PEPPOL network (Pan-European Public Procurement Online) to transmit e-invoices.
-
Norway follows the 4-corner model: You (the sender) → your access point → recipient’s access point → recipient.
-
You need a registered PEPPOL Access Point provider to send or receive invoices.
-
Invoices must use the EHF format (Electronic Commerce Format) which is Norway’s localized version of PEPPOL BIS 3.0.
-
Recipient information is stored in the national ELMA directory, listing over 200,000 registered entities.
-
Over 95% of all e-invoices in Norway flow through the PEPPOL network.
Government Portal: What is Altinn?
Altinn is Norway’s government platform for businesses. It offers:
-
Guides on how to comply with e-invoicing regulations
-
Registration and management of company information
-
Resources for choosing the right invoicing solution
Altinn does not send or receive e-invoices but supports companies in becoming compliant.
PEPPOL Architecture:
4-Corner vs. 5-Corner
-
4-Corner Model: Norway's current system. Sender and receiver each work with their own access point. PEPPOL handles the delivery.
-
5-Corner Model (future possibility): Adds a tax authority or central platform that receives a copy of each invoice in real time.
Norway is currently exploring real-time reporting options (e.g., SAF-T), but the 5-corner model is not yet implemented.
