In the context of a public procurement or concession contract, all economic operators must, with some exceptions, issue and submit their invoices in the form of compliant electronic invoices:

• using the Peppol network; or
• if they are not or not yet connected to Peppol, by using one of the 2 types of online forms available on MyGuichet.lu, namely:
  • a form which allows to manually enter in the fields of the form the elements of an invoice and then to transmit these data; or
  • a form that allows you to upload an already compliant electronic invoice and then to transmit it.

With MyGuichet.lu, it is possible to submit procedures online, with or without strong authentication.

The person who carries out a procedure with authentication needs :

• a business eSpace on the MyGuichet.lu platform; and
  
• a LuxTrust product; or
• an electronic identity card (eID); or
• a digital ID issued by another EU country (eIDAS).

The person submitting the procedure without authentication needs a one-time access code (token) for each invoice. This must be requested in advance from the public sector body with which the public contract or concession contract has been concluded (contracting authorities or entities or concession authority).
