Public procurement contracts and concession contracts: issuing and submitting an electronic invoice using

Since 18 May 2022, large economic operators must, within the framework of a public procurement or a concession contract, issue and submit their invoices only in the form of a compliant electronic invoice.

All public-sector organisations, i.e. all tendering authorities and entities, must be able to receive compliant electronic invoices via the European delivery network Peppol (Pan-European Public Procurement OnLine).

Economic operators, who are not yet connected to the Peppol network, have 2 alternative non-automated technical solutions on They can:

  • manually complete a data entry form for their invoice; and/or
  • submit (upload) an already compliant electronic invoice via a form.

The person submitting the invoice must have a business eSpace on the platform. To create it, they will need:

  • a LuxTrust product; or
  • an electronic identity card (eID); or
  • a digital ID issued by another EU country (eIDAS).

It is reminded that the obligation then will apply:

  • from 18 October 2022, to medium-sized economic operators; and then
  • from 18 March 2023, to small economic operators, hence from this point forward, to all economic operators.
