Frequently asked questions
Is B2B e-invoicing mandatory in Denmark?
Not as a direct invoice mandate — but the Bookkeeping Act requires digital bookkeeping systems capable of sending and receiving e-invoices, which drives near-universal adoption in practice.
NemHandel or Peppol?
They interoperate and Denmark is converging national specifications with Peppol. A Peppol connection reaches Danish public and private receivers.
