Top 4 Invoicing Software for Denmark in 2025

Denmark has long been a pioneer in digitization, and the landscape for invoicing software is shifting rapidly due to new government mandates. For founders and SMBs, choosing the right software is no longer just about convenience—it is about legal compliance with the Danish Bookkeeping Act (Bogføringsloven).

This guide highlights the top European-built invoicing and accounting tools that align with Denmark's specific regulatory requirements, including OIOUBL formats and NemHandel integration.

Danish Invoicing & Regulatory Context

Before selecting a tool, you must understand the "Digital Bookkeeping System" requirements enforced by the Danish Business Authority (Erhvervsstyrelsen).

The New Bookkeeping Act (Bogføringsloven)

Denmark is phasing in a mandatory requirement for businesses to use "registered digital bookkeeping systems."

• July 1, 2024: Became mandatory for companies using standard digital systems to book digitally.
• January 1, 2025: Becomes mandatory for companies using custom-built systems.
• 2026: Extension to certain smaller personally-owned companies (turnover > 300,000 DKK) not previously obliged to submit annual reports.

Key Compliance Features

To be a compliant system in Denmark, the software must:

1. Support OIOUBL & Peppol: Be able to send and receive electronic invoices in OIOUBL and Peppol BIS 3.0 formats.
2. NemHandel Integration: Connect to the Danish infrastructure for e-commerce.
3. Digital Storage: Store registration and attachments safely in the cloud for 5 years.
4. IT Security: Meet specific standards for backup and access control.

HQ: Copenhagen, Denmark

e-conomic is the undisputed market leader in Denmark, used by over 200,000 businesses. Now owned by Visma, it remains a distinctly Danish product at its core.
