E-invoicing is no longer optional. It is already mandatory for invoices to the Luxembourg public sector, and the B2B obligation is taking shape for 2028-2030. Good news for Galux clients: we take care of it for you, at no extra cost.
📅 Where does Luxembourg stand?
The Luxembourg e-invoicing roadmap is now public. Four milestones every business should keep in mind:
B2G: mandatory since 2019
Since 18 April 2019, formalised by the law of 13 December 2021, every invoice issued to a Luxembourg public entity (State, municipalities, public establishments) must be sent in structured electronic format via the PEPPOL network. The obligation applies to all companies, with no turnover threshold. A PDF invoice sent by email is no longer accepted by the public sector.
B2B: not mandatory yet, but it's coming
Business-to-business e-invoicing remains voluntary in Luxembourg in 2026. But ViDA was adopted at EU level in April 2025, and the Luxembourg legislator is now drafting the national framework that will plug into it.
⚙️ How does it work in practice?
The Luxembourg standard is PEPPOL (Pan-European Public Procurement Online), a secure network that transports invoices in structured XML format. Three building blocks:
The invoice is machine-readable data, not a PDF. Standardised fields, automated validations, no re-keying on either side.
Invoices transit via certified Access Points, each company identified by a PEPPOL ID (often based on its VAT number).
The same invoice flows to Luxembourg, Belgium, the Netherlands or Germany without a single change.
🎁 The Galux offer: PEPPOL-ready, on the house
Rather than asking you to invest in invoicing software and subscribe separately to a PEPPOL provider, Galux gives you the full solution directly. Everything below is included in your engagement, with nothing extra to install or buy:
In practice, you click "Send" from your accounting application and we handle the rest. The invoice is converted to PEPPOL XML and routed automatically to the recipient. No additional software to buy, no separate subscription, no setup fees.
📊 Your benefits in numbers
Accounting application, PEPPOL Access Point and regulatory updates are all bundled in your Galux package.
If you invoice the public sector, you are already compliant — no extra steps to take.
When the B2B obligation comes in 2028-2030, you will already be set up.
Automatic validation of VAT number, format and amounts — fewer rejected invoices, less back and forth.
Eligible companies can have up to 70% of implementation costs covered by the SME Packages Digital programme (projects from €3,000 to €25,000 net).
