Fundamentals – What Is E-Invoicing in Norway?

E-invoicing in Norway refers to the structured electronic exchange of invoice data between businesses and public authorities.

Unlike traditional PDF invoices, it is based on standardized, machine-readable formats that can be processed automatically by IT systems without manual intervention.

Importance of E-Invoicing in Norway

• E-invoicing has been established in Norway for many years and is a core component of digital public administration.
• The country adopted standardized formats and automated processes at an early stage.
• As a result, Norway is considered a leading model for electronic invoicing in Europe.

---

Legal Requirements for E-Invoicing in Norway

The legal framework is clearly defined and particularly strict in the public sector.

Mandatory in the B2G Sector

• Companies are required to submit invoices to public entities in electronic format.
• The use of the PEPPOL network is legally mandated.
• Invoices in alternative formats, such as PDF, are generally not accepted by public authorities.

B2B Sector

• There is currently no legal obligation for e-invoicing between private companies.
• However, many organizations adopt e-invoicing voluntarily to improve efficiency.
• Adoption continues to grow due to international requirements and increasing automation needs.

---

Formats – What Is EHF 3.0?

The primary invoicing standard in Norway is EHF 3.0.

EHF 3.0 (Elektronisk Handelsformat)

• EHF 3.0 is based on PEPPOL BIS specifications and is internationally compatible.
• It is an XML-based format that enables structured, machine-readable data exchange.
• Public sector organizations require this format for invoice processing.
• Only properly validated EHF invoices can be processed automatically.
• To be accepted, electronic invoices in Norway must comply with this format.

What Role Does SAP Play in E-Invoicing in Norway?

For many companies, SAP serves as the central platform for implementing e-invoicing processes.

SAP DRC (Document and Reporting Compliance)

• SAP DRC enables the creation of compliant EHF invoices directly within the system.
• It provides connectivity to the PEPPOL network through dedicated interfaces.
• Companies can meet regulatory requirements in an automated and scalable way.

SAP VIM (Invoice Processing)

• SAP VIM fully automates the processing of incoming invoices.
• It manages approval workflows and significantly reduces manual effort.
• At the same time, it ensures transparency and traceability across the entire invoicing process.

How Does the PEPPOL System Work?

The backbone of e-invoicing in Norway is the PEPPOL network.

Key Components

• Access Points act as certified gateways to the PEPPOL network.
• Each organization requires a unique PEPPOL ID for identification.
• Standardized document formats ensure interoperability between systems.
• Invoices are securely transmitted via certified Access Points.

How Does Norway Compare to Germany?

A brief comparison highlights key differences:

• Norway uses a single standardized format (EHF 3.0) for public invoicing.
• Germany relies on multiple formats such as XRechnung and ZUGFeRD.
• PEPPOL is mandatory in Norway, while only partially adopted in Germany.
• Norway’s level of digital maturity is significantly higher.

➡️ Overall, Norway is clearly more advanced in e-invoicing adoption.

Monitoring & Operations

After go-live, stable operations become critical.

What Needs to Be Monitored

• The delivery status of invoices must be tracked continuously.
• Errors must be identified and resolved quickly.
• Validation issues should be analyzed and prevented long term.
• Delivery confirmations ensure successful transmission.

Typical KPIs

• Processing time measures the speed of invoice handling.
• Error rates highlight areas for improvement.
• The automation rate reflects overall process efficiency.

➡️ The goal is continuous optimization.

How to Further Increase Automation

E-invoicing is often just the first step in digital transformation.

Further optimization opportunities include:

• Automatic account assignment for invoices.
• AI-based validation and error detection.
• Fully automated and accelerated workflows.

• Goods are delivered.
• The invoice is generated automatically.
• It is converted into EHF 3.0 format.
• The invoice is validated according to PEPPOL rules.
• It is transmitted via an Access Point.
• The authority receives and processes the invoice automatically.

➡️ Result:

• No manual intervention is required.
• The entire process is fully automated and highly efficient.
