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.
-
Norway has also proposed new legislation that would require businesses with bookkeeping obligations to issue e-invoices from 1 January 2027.
-
From 1 January 2030, digital bookkeeping and e-invoice reception requirements are expected to apply as well.
-
E-invoices must follow the EHF format (based on PEPPOL BIS Billing 3.0).
-
For B2B, e-invoicing is currently voluntary, but this is under review by the Norwegian government.

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. 
How to Send E-Invoices in Norway 
Choose one of the following: 
-
​ERP or Accounting Software (that supports PEPPOL/EHF) 
-
Web-based invoicing portals for manual entry 
-
Access Point providers (for automated integration) 
-
Note: Sending e-invoices via email as a PDF is not valid for public entities. 
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.
