Peppol in Luxembourg: Is your business ready for mandatory B2B e-invoicing?

Written by Guillaume Frankart | Aug 24, 2026, 7:03:58 AM

E-invoicing is no longer just a public-sector requirement in Luxembourg.

Following the approval of a draft law extending electronic invoicing to domestic B2B transactions, companies will progressively be required to exchange structured electronic invoices through a compliant framework. The first milestone arrives sooner than many organizations realize. The real question is no longer if your business will be concerned. It's when you'll be ready. And the good news is simple: Easi already is.

Peppol: from B2G obligation to B2B standard

Peppol, which stands for Pan-European Public Procurement On-Line, has become the reference framework for exchanging structured electronic documents across Europe. More than just an invoicing format, it is a secure network that enables organisations to send and receive electronic documents in a standardised, traceable and automated way.

The upcoming B2B reform builds on this existing infrastructure and on the European EN 16931 standard, making Peppol the natural choice for businesses preparing for the next phase of digital invoicing.

The full timeline 

Date  What happens
2022 Peppol e-invoicing becomes mandatory for large companies invoicing Luxembourg public sector organisations (B2G).
18 March 2023 Peppol e-invoicing becomes mandatory for all suppliers invoicing Luxembourg public sector organisations (B2G). 
1 January 2028 All Luxembourg businesses must be able to receive compliant electronic invoices for domestic B2B transactions. 
1 July 2028 Medium-sized and large companies must issue electronic invoices for domestic B2B transactions. 
1 January 2029 The obligation to issue electronic invoices extends to all businesses, including SMEs and micro-enterprises. 

Why act now?

Preparing for e-invoicing is not simply about compliance.

Companies that adopt Peppol early can already benefit from:
•    automating invoice exchanges,
•    reducing manual data entry and errors,
•    improving traceability and security,
•    accelerating invoice processing and payments. 

The organizations that start early will face a smoother transition and be ready well before the deadlines arrive.

Conclusion & next step

For Luxembourg-based companies, compliance with Peppol is quickly becoming a strategic necessity rather than an option for the future. 

The infrastructure is already in place. The legal framework is now in place. The deadlines are approaching.
