Facturio Invoices for WooCommerce

Description

Facturio Invoices for WooCommerce turns every WooCommerce order into a compliant Factur-X invoice: a human-readable PDF with a structured XML file (EN 16931 profile) embedded inside it, which accounting software and the tax administration can read automatically. Factur-X is the pivot format chosen by France for the 2026-2027 e-invoicing reform.

The plugin is built for French WooCommerce stores that sell to businesses (B2B) and must issue compliant electronic invoices, without changing their accounting software.

Free version features (V0.1)

  • Automatic generation of an EN 16931 Factur-X invoice when an order reaches the “processing” or “completed” status (your choice).
  • Hybrid PDF/A-3: the CII XML (factur-x.xml) is embedded in the PDF, with the Factur-X XMP metadata and the /Alternative relationship required by the standard.
  • Business number validation at checkout:
    • SIRET checked live against the INSEE Sirene API (the legal company name is fetched automatically).
    • Intra-community VAT number checked against the European Commission VIES service.
  • Tamper-proof sequential numbering (format F2026-000001), with no gaps and no duplicates, as required by French law.
  • Set the next invoice number to resume an existing series — useful when migrating from another tool mid-year (the plugin refuses any value that would reuse a number).
  • B2B checkout fields: an “I am ordering for my company” checkbox plus company name, SIRET, VAT and APE code.
  • Customisable logo and primary colour on the invoice.
  • Download the invoice from the orders list and the order edit screen, with a regenerate option.
  • Automatic email delivery: the invoice is attached to the WooCommerce order email sent to the customer.
  • HPOS compatible (High-Performance Order Storage).
  • French interface, translation-ready (a .pot file is included).

Not included in the free version (yet)

  • Automatic routing to an accredited platform (Plateforme Agréée / former PDP) — planned for the Pro version.
  • Automatic B2C e-reporting — planned for the Pro version.
  • Credit notes, the EXTENDED-CTC-FR profile and multi-store — planned for later versions.

Compliance validation

Generated invoices are designed to pass the official FNFE-MPE validator (https://services.fnfe-mpe.org/): valid PDF/A-3, valid XMP, valid XML against the EN 16931 XSD and Schematron.

External services

This plugin validates business identifiers against two official third-party services. A request is sent only when a SIRET or VAT number is entered in the B2B checkout fields (or saved in the settings); nothing is sent otherwise. The plugin includes no analytics and no tracking.

  • INSEE Sirene API — when a SIRET is entered, the 14-digit SIRET is sent to the INSEE Sirene API to confirm the establishment exists and to retrieve its legal company name. A request is made only if you have configured your own (free) INSEE API key; with no key, the SIRET is only checked locally and nothing is sent. Service: https://api.insee.fr/ — Terms: https://api.insee.fr/catalogue/ — Privacy: https://www.insee.fr/fr/information/2381863
  • European Commission VIES — when an intra-community VAT number is entered, that VAT number is sent to the EU VIES service to check its validity (and, when the member state returns it, the trader name). Service & terms: https://ec.europa.eu/taxation_customs/vies/

No invoice content or customer data is sent to the plugin author or to any other server.

  1. Install and activate the plugin from the “Plugins” screen in WordPress.
  2. Activate WooCommerce if it is not already.
  3. Go to WooCommerce Settings Factur-X.
  4. Fill in your seller details: legal name, SIRET, intra-community VAT number, address, APE code, legal mentions.
  5. In the Integrations tab, paste your INSEE Sirene API key (free, request it at https://portail-api.insee.fr/) to enable SIRET validation at checkout.
  6. In the Appearance tab, choose your logo and primary colour.
  7. Choose the trigger status for automatic generation (“processing” or “completed”).

Done: every new order reaching that status generates its Factur-X invoice.

Do I need an API key for the plugin to work?

The plugin generates compliant Factur-X invoices without any key. The (free) INSEE Sirene key is only used to verify SIRET numbers live at checkout and to pre-fill the company name. Without it, only the local format of the SIRET is checked.

Does the plugin route my invoices to an accredited platform?

Not in the free version. V0.1 produces and archives the compliant Factur-X invoice. Routing to accredited platforms (Iopole, B2Brouter, Pennylane, etc.) is planned for the Pro version.

Are my generated invoices deleted if I uninstall the plugin?

No. Uninstalling removes only the plugin settings and its temporary caches. It keeps your whole invoice archive: the PDF files in wp-content/uploads/factur-x/, the invoice records, the B2B data stored on your orders, and the numbering counter — because invoices are legal documents that must be archived, and so that a later re-install never re-issues an already-used number.

Is the plugin compatible with High-Performance Order Storage (HPOS)?

Yes. HPOS compatibility is declared and all order reads/writes go through the WooCommerce API.

VAT validation shows “service unavailable” — is that a bug?

No. The European VIES service (and the French registry in particular) limits the number of concurrent requests and is regularly down. The plugin retries automatically, and checkout is never blocked: only the local format check is required.
