E-invoicing is becoming mandatory in Luxembourg — already for public procurement, soon for B2B. Good news for Galux clients: we take care of it for you, at no extra cost. Galux gives access to each client to its accounting system, ready for Luxembourg e-invoicing via the PEPPOL network — included in your package, with no software fees on your side.
Where does Luxembourg stand?
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 the timeline is taking shape:
- 2026: a Luxembourg national law on e-invoicing and digital tax reporting is expected to be adopted.
- Mid-2028 to early 2029: likely entry into force of the domestic B2B obligation in Luxembourg.
- 1 July 2030: the EU ViDA (VAT in the Digital Age) directive, adopted in April 2025, will make e-invoicing and near real-time digital reporting mandatory for all intra-EU B2B transactions.
Companies that wait may find themselves scrambling in 2028. Anticipating costs less — especially when your accounting firm anticipates for you.
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 key elements:
- Structured format (XML): the invoice is machine-readable data, not a PDF. Standardised fields, automated validations, no re-keying.
- PEPPOL network: invoices transit via certified Access Points, identified by a PEPPOL ID (often based on the VAT number).
- European interoperability: the same invoice flows to Luxembourg, Belgium, the Netherlands or Germany without changes.
The Galux offer: your free accounting application, already Luxembourg-compliant
Rather than asking you to invest in invoicing software and subscribe separately to a PEPPOL provider, Galux gives you the full solution directly:
- A dedicated accounting application for your company — at no licence cost to you.
- The PCN 2020 chart of accounts aligned with Luxembourg standards, pre-installed.
- Up-to-date VAT codes (17%, 14%, 8%, 3%, intra-community, exempt…).
- Invoice issuance in the PEPPOL BIS Billing 3.0 format, accepted by every Luxembourg and European administration.
- An integrated PEPPOL Access Point: no third-party provider to subscribe to.
- Continuous regulatory updates: when the rules change, your accounting application stays compliant — without any action on your side.
In practice, you click "Send" from your database 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.
"Our clients have nothing to buy, nothing to install, nothing to configure. Everything is included: the database, PEPPOL compliance, eCDF, regulatory updates. That is what a modern accounting firm should provide."
Your concrete benefits with Galux
- Zero software cost on your side: the database, the PEPPOL Access Point and the regulatory updates are included in your Galux package.
- Immediate B2G compliance: if you invoice the public sector, you are already compliant — no extra steps.
- B2B-ready in advance: when the B2B obligation comes in 2028-2030, you will have nothing to change.
- Faster payments: structured invoices are processed and paid 30-50% faster than PDFs.
- Fewer errors: automatic validation of VAT number, format and amounts. Fewer rejected invoices.
- Stackable subsidy: eligible companies can have up to 70% of e-invoicing implementation costs covered by the SME Packages Digital programme (projects from €3,000 to €25,000 net) — additional cash savings on top of what is already free with Galux.
