Guide: Understand EAN invoicing for the public sector

Have you got your first public customer, and Do you need to invoice for your work?

Do you sit and get confused by words like EAN number, NemHandelsregisteret and OIOUBL format?

Having to move into the EAN area can seem long-winded and confusing, so if you're left wide-eyed and wondering, don't worry.

We have created a thorough guide so that you can feel both safe and secure when sending EAN invoices.

What is an EAN invoice?

An EAN invoice is an electronic invoice that uses an EAN number (European Article Number), which is a digital invoicing method that can be used between companies in Denmark's NemHandelsregister and public institutions. EAN invoicing is often used by public institutions and larger companies to handle invoices more efficiently and automate accounting processes.

CVR vs. EAN - What's the difference?

CVR is an abbreviation for "The Central Business Register", and is the state's register and information portal for Danish companies.

All Danish companies must be CVR registered and have a CVR number. However, with a few exceptions for companies with an annual turnover of DKK 50,000 or less.

EAN, on the other hand, is an abbreviation of "European Article Numbering".

An EAN number is used for invoicing to public bodies, e.g. to municipalities, regions or companies established in NemHandelsregisteret.

Where CVR invoicing primarily takes place via e-mail with an invoice attached as a PDF file or via letter, invoicing to the public sector takes place through e-invoicing via an EAN number.

E-invoicing

… Or electronic invoicing is a direct and electronic version of an invoice, where the invoice is created and processed in an electronic format between supplier and customer.

Electronic invoicing has many advantages:

  • Your invoices are executed quickly
  • Your invoices are posted automatically
  • You can easily send electronic receipts or reminders
  • You can easily invoice both the public and the private sector
  • Minimizing manual errors

There are various accounting systems that you can use to create an e-invoice, which we present to you at the end of this post.

EAN invoicing for the public sector

To be able to send an EAN invoice to the public you must first get hold of the 13-digit EAN number, where for a regular invoice you would instead invoice via a CVR number. 

The EAN number can be seen as the institution's or company's electronic address and ensures that your invoice ends up in the right place. 

You can obtain the EAN number from the company or institution to which you must invoice, either directly or by searching on their website. 

An institution with several departments may have different EAN numbers, which is a good idea to be aware of when invoicing. 

There may also be some public recipients who invoice via their CVR number. 

When the company receives an EAN invoice, they can pay from there via their system. If you do not invoice via an EAN number to these bodies, your invoice will be rejected.
