What is Peppol and what role does it play in Luxembourg?
Peppol (Pan-European Public Procurement OnLine) is a standardised international network for exchanging electronic business documents. In Luxembourg, Peppol has played a central role in digitalising exchanges with the public sector since 2023.
Luxembourg was one of the first European countries to transpose Directive 2014/55/EU, making e-invoicing mandatory for public procurement (B2G). For B2B exchanges, Peppol adoption is voluntary but growing rapidly.
Since 2023, every invoice to the Luxembourg public sector (State, municipalities, public institutions) must be sent in structured electronic format.

Peppol is simple and transparent. Here are the 4 steps:
Registration

Automatic reception
Suppliers and public administrations send invoices via Peppol. They arrive automatically in your inbox.
Send invoices
Send invoices to public administrations and B2B clients via the Peppol network. EN 16931 format generated automatically.

E-invoicing in Luxembourg: B2G and B2B
Luxembourg transposed EU Directive 2014/55/EU: e-invoicing is mandatory for public procurement (B2G) since 2023. For B2B, usage is voluntary but increasingly widespread.
MyGuichet.lu allows sending invoices to the public sector. Peppol Box offers a more comprehensive solution for recurring flows and B2B exchanges.
For public procurement: non-compliant invoices may be rejected by the administration. Make sure you are equipped.
