E-Invoicing in Norway: The Timeline

Timeline of E-Invoicing in Norway.
Timeline of E-Invoicing in Norway.


In 2011, Norwegian entities were mandated to receive electronic invoices from suppliers.


In 2012, partners trading with Norwegian entities were mandated to send only structured e-invoices. The new requirement positioned Norway as one of Europe's early adopters of electronic invoicing before Directive 2014/55/EU.


Norway passed the FOR-2019-04-01-444 regulation, mandating non-central public bodies to receive and process electronic invoices.

The law also required suppliers to non-central public bodies to send structured invoices only. In addition, these e-invoices must conform to the EU Norm using the Peppol BIS or EHF standard.

The requirement also affects all central government bodies issuing invoices.


In 2020, the Norwegian authorities set up a system to monitor and track the implementation of e-invoicing in central and non-central public entities.

E-invoicing in Norway applies to all B2G transactions. The obligation affects all entities selling goods or services to the public sector, including businesses and individuals.

Despite the lack of mandatory policies, the adoption of e-invoicing in Norway is becoming widespread among B2B companies and private businesses.

  • Use EHF Billing 3.0 or Peppol BIS 3.0, the standard e-invoicing formats in Norway.
  • Register with ELMA, the Norwegian electronic invoicing platform.
  • Transmit invoices through ELMA, which then forwards them to the correct access point.

Who Governs e-Invoicing and e-Procurement in Norway

Norway uses the ELMA platform to verify electronic invoices. The Norwegian government created the platform in partnership with private companies.

The Norwegian Directorate for Public Procurement (DnD) is in charge of the country’s electronic invoicing policy.

How Norwegian B2B Businesses Stand to Benefit by Adopting e-Invoicing

E-invoicing has become an increasingly popular solution in Norway. Key benefits of ditching paper invoices include:

  • Increased Compliance: While electronic invoicing in Norway isn't mandatory for B2B transactions, it provides businesses with a more secure and efficient way of processing payments while meeting the requirements of Norwegian tax law.
  • Improved Cash Flow: E-invoicing speeds up the invoicing and payment process, allowing businesses to get paid for goods and services more quickly and efficiently.
  • Enhanced Data Accuracy: E-invoicing eliminates the possibility of errors or inconsistencies in manual data entry. The benefit is greater accuracy and reliability for their financial data.
  • Increased Security: Electronic invoicing offers a secure platform for transmitting sensitive financial information, reducing the risk of fraud and unauthorized access to sensitive data.
  • Reduced Costs: E-invoicing eliminates the need for paper, printing, and postage costs, making it a more cost-effective solution for B2B businesses in Norway.
  • Improved Visibility and Traceability: E-invoices provide greater visibility into the payment process. As a result, businesses can track the status of invoices and payments in real-time, enabling them to manage their cash flow more effectively.

Increased Sustainability: By cutting the need for paper, e-invoicing helps reduce business operations' environmental impact and promote sustainability. Sustainability is becoming an increasingly essential responsibility for businesses globally.

Electronic invoicing offers a more efficient, secure, and cost-effective solution for B2B businesses in Norway and helps to ensure compliance with Norwegian tax law and financial regulations.

Key Takeaways

How to Send Electronic Invoices in Norway

The Norwegian electronic invoicing is anchored on Peppol Network and relies on the Peppol eDelivery Network and Peppol BIS 3.0. Businesses and companies looking to send and receive invoices need to connect to Peppol Network via an authorized access point provider like Unimaze.

Peppol e-invoicing is a four-part process broken down as follows:

1. Access Point: The parties sending and receiving invoices must connect to the Peppol network to exchange invoices via an access point provider.

2. Sender: To send an e-invoice, the sender must use a Peppol-compliant solution. Unimaze e-invoicing software integrates into your ERP without the need to upgrade your system.

ELMA, the Norwegian national Peppol Metadata Publisher (SMP), allows businesses in the country to connect to the Peppol network to verify they’re sending compliant e-invoices.

3. Recipient: Like the sender, the entity receiving e-invoices must use a Peppol-compliant software solution.

4. Paying the Invoice: The Peppol network allows businesses to pay invoices electronically, quickly, and efficiently.

Electronic Invoices in Norway - FAQs

Is Digital Signature a Requirement for e-Invoices in Norway

No, a digital signature isn’t required for Norwegian e-invoices. Still, a digital signature provides authenticity and integrity to your invoice, ensuring it is trustable and isn’t tampered with.

What is EHF in Norway?

EHF (Electronic HandelsFormat) is the standard for electronic invoicing in Norway.

It is a standardized format for electronic invoices used by the public sector and private businesses in Norway for exchanging invoices electronically.

EHF invoices are mandatory for all public sector organizations in Norway and are also widely used in the private sector.

Is Norway Part of the EU For VAT Purposes?

No, Norway is not part of the European Union (EU) for Value Added Tax (VAT) purposes.

While the country is part of the European Economic Area (EEA), it isn't a member of the EU and, therefore, not subject to EU VAT rules and regulations.

Instead, Norway has its own VAT system and operates independently from the EU regarding VAT.

Norwegian businesses must comply with the country's VAT rules and regulations, including registering for VAT, charging the correct VAT rate on taxable supplies, and filing VAT returns with the Norwegian tax authorities.

Should I Charge VAT On Services to Norway?

The need to charge VAT on services to Norway depends on several factors, including your location and the nature of the services being provided.

If you’re operating outside of Norway, you may not be required to charge VAT on services you provide to Norwegian customers as long as they aren’t taxable in Norway.

However, if you are based in Norway, you will be required to charge VAT on services provided to customers in Norway, regardless of their location.

We recommend checking with the Norwegian tax authorities for guidance on your situation.

What is SAF-T Norway?

SAF-T (Standard Audit File for Tax) is a standard for the electronic reporting of financial and accounting data in Norway.

It was introduced by the Norwegian government to improve the efficiency of tax audits and to make it easier for businesses to comply with tax reporting requirements.

Under the SAF-T standard, businesses must electronically report financial and accounting data to the Norwegian tax authorities using a specific file format.

This file must include information such as sales and purchase invoices, bank statements, and ledger accounts. The data must be provided on time, typically on a quarterly or monthly basis, and must be accurate and complete.
