Denmark: E-Invoicing to Become the Common Way of Invoicing
The Danish Business Authority (Erhvervsstyrelsen) has announced a new executive order introducing requirements for registered digital bookkeeping systems, which are currently used by around 350,000 Danish businesses. The aim is to make e-invoicing easier to adopt; the authority estimates nationwide savings of up to DKK 9 billion per year if all businesses switch.
Key points:
MitID validation: By 1 March, providers of registered bookkeeping systems must ask their customers to validate their business with MitID.
Automatic enrolment (opt-out): Providers must then inform customers that they will be automatically enrolled in e-invoicing unless they actively opt out.
Not exclusive: Enrolled businesses can still agree on other invoice formats with their customers and suppliers.
Early enrolment: Businesses can already ask their system provider to enrol them before the automatic process.
