E-Invoicing in Denmark: Everything Businesses Need to Know

Denmark has been a pioneer in electronic invoicing for nearly two decades. Since 2005, public sector suppliers have been required to send their invoices digitally through the national NemHandel platform. With the adoption of the Danish Bookkeeping Act, these requirements are expanding to include private companies as well, creating a unified and more transparent invoicing ecosystem.
Electronic invoicing or e-invoicing is more than a compliance measure. It supports economic growth, reduces errors, and improves payment efficiency for businesses of all sizes.
Why Denmark is Moving to E-Invoicing?
The Danish government has committed to modernizing financial processes by promoting digital bookkeeping. While B2G (Business-to-Government) e-invoicing has been mandatory since 2005, B2B (Business-to-Business) invoicing has mostly relied on voluntary adoption. That is now changing with the Bookkeeping Act, which will expand mandatory requirements to more business segments in the coming years.
Some key reasons Denmark is pushing e-invoicing forward:
Reduce tax fraud and increase transparency
Cut manual, paper-based processes
Promote secure, standardized document exchange
Support cross-border and EU-wide trade
Denmark’s E-Invoicing Regulations Explained
Here’s what you should know about the current and upcoming regulations:
Since 2005, public sector suppliers must send invoices digitally
The NemHandel platform, launched in 2007, supports secure B2G e-invoicing
From 2024, medium and large companies using standard accounting software must adopt certified bookkeeping solutions
From 2025, medium and large companies using custom-developed software must also comply
From 2026, financial companies and personally managed businesses with revenue above 300,000 DKK will fall under mandatory rules
Supported invoice formats include OIOUBL (UBL 2.0) and PEPPOL BIS 3.0Archiving is required for a minimum of five years
Electronic signatures are not mandatory
While B2B invoicing is not fully mandatory yet, best practices and growing momentum are making it essential for companies to adopt standardized e-invoicing sooner rather than later.
Denmark E-Invoicing Rollout Timeline
January 2024: The Danish Business Authority publishes the official list of certified bookkeeping systems
July 2024: Medium and large companies with standard systems must start using certified software
January 2025: Medium and large companies with custom software must ensure their systems are certified
January 2026: Financial institutions and personally managed businesses with turnover above 300,000 DKK must also comply.
Businesses below the turnover threshold can continue using their existing systems, but must still meet other bookkeeping and archiving rules.
How the NemHandel Platform Works
Denmark’s e-invoicing is built around the NemHandel infrastructure. This secure national platform acts as a hub where public authorities and private suppliers can exchange e-invoices and other business documents.
Any supplier doing business with the Danish public sector must connect their ERP or accounting system through an authorized access point. The access point guarantees that data meets Denmark’s strict security and validation standards.
What is Peppol in Denmark?
Denmark is also a strong promoter of the Peppol network. The Danish Business Authority (ERST) acts as the national Peppol Authority and oversees registration and approval of Peppol Access Point providers.
Peppol allows businesses to exchange e-invoices and procurement documents across borders, supporting European and international trade. In Denmark, Peppol is complementary to NemHandel and uses the same core data standards, including OIOUBL and Peppol BIS 3.0 formats.
Benefits of Adopting E-Invoicing in Denmark
Switching to an electronic invoicing platform offers clear advantages:
Time Savings Digital workflows remove the delays of postal or email-based PDF invoices, meaning you get paid faster and spend less time chasing payments.
Cost Savings No paper, no printing, no postage. Plus, fewer errors and reduced manual work lower your total invoicing costs.
Better Tracking and Transparency With real-time status updates, you always know when an invoice is delivered, viewed, and paid. This improves cash flow and reduces disputes.
Fewer Errors E-invoicing minimizes manual data entry, helping you avoid mistakes that can cause delays or even tax compliance problems.
Improved Customer Experience Customers get standardized, clear, and easily archivable invoices, which speeds up their approval and payment processes.
Stronger Compliance As Danish rules expand, you will already be prepared with a certified, audit-ready system.
