Automatic Factur-X e-invoicing for Dolibarr. Every validated client invoice is converted into a compliant Factur-X EN 16931 file (a PDF/A-3 with the CrossIndustryInvoice XML embedded), ready for the 2026 French e-invoicing reform. Chorus Pro (B2G) is supported, and the injection works with both native PDF and ODT invoice models.

More info...
LemonFacturX turns every Dolibarr client invoice into a compliant Factur-X (EN 16931) electronic invoice, automatically. On each generated invoice, the module embeds a CrossIndustryInvoice XML and produces a valid PDF/A-3, the format required by the French e-invoicing reform.
Features
- Fully automatic: no manual step. Each validated client invoice becomes a Factur-X PDF/A-3 with the embedded EN 16931 XML.
- French compliance (BR-FR): SIRET and SIREN placed in the correct CII fields (ISO 6523 scheme IDs), mandatory legal mentions, VAT exigibility, VAT franchise handling, credit notes, document discounts, intra-community supplies.
- Chorus Pro (B2G): for public-sector invoices, an additional Chorus-profile PDF is generated (service code, engagement, contract reference) without altering the standard Factur-X.
- ODT invoice models (since 3.8.0): the Factur-X is also injected into invoices generated from an ODT template converted by LibreOffice, not only the native TCPDF models.
- Verify & Regenerate: buttons on the invoice card to re-check the embedded XML (XSD + business rules) before sending, or regenerate the Factur-X after a data fix.
- Built-in diagnostic: a configuration checklist flags anything missing for full compliance (embedded fonts, seller data, bank account, VAT number format).
- REST API & batch export: read the embedded XML and compliance status through the API, export the XML in bulk.
- Robust injection: isolated subprocess by default, with an in-process fallback so it also runs on hardened or shared hosting where exec() is disabled.
Validation
Each generated XML is validated against the EN 16931 XSD and a set of business rules (BR-*) before injection. Optional PDF/A-3 post-validation with veraPDF.
