Frequently Asked Questions
Is e-invoicing mandatory in Luxembourg?
For the public sector (B2G), yes. Since 18 March 2023, all suppliers — including small and newly established businesses — must send PEPPOL e-invoices to Luxembourg public bodies. B2B and B2C e-invoicing remain voluntary as of 2026, though a future B2B mandate is anticipated.
Do you support French and German invoicing?
Yes. Cauri supports both French and German, covering Luxembourg's multilingual business environment. You choose the language per invoice.
How does Luxembourg VAT validation work?
We run VAT format checks (LU followed by 8 digits) and EU VIES pre-checks to flag issues before you send. Please confirm official records with the AED (Administration de l'enregistrement, des domaines et de la TVA) for accuracy.
Can I invoice clients in other EU countries?
Yes! Through PEPPOL, you can send e-invoices to 32 European countries, including all EU members. Cross-border compliance is automatic.
