Every order automatically gets a legally compliant PDF invoice with an embedded **Factur-X** XML file (PDF/A-3, profile **EN 16931**) — the format required by the French e-invoicing reform (réforme de la facturation électronique, échéances 2026–2027). **Automatic. On every order.** #### Features * **Automatic generation** of a Factur-X invoice when the order reaches the status you choose (processing — the default — or completed) — no clicks needed. An order that jumps straight to completed is invoiced then; each order is invoiced exactly once. * **PDF/A-3 with embedded EN 16931 CII XML**, validated against the official Factur- X XSD schemas at generation time. * **French legal invoice layout**: seller block (raison sociale, forme juridique, capital, RCS, SIRET, TVA), buyer block, line items HT, VAT breakdown by rate, totals HT/TVA/TTC, payment terms, and the mandatory legal mentions (pénalités de retard, indemnité forfaitaire de 40 €, escompte). * **Gap-free sequential numbering** (prefix + year + counter, optional yearly reset)— race-safe, numbers are immutable once issued, regeneration never changes the number. * **B2B checkout fields**: optional SIRET and intra-community VAT number on the classic checkout, validated (Luhn / FR VAT key) and shown in the admin order screen and in the XML. * **Customer access**: download link in My Account Orders, on the order-received page, and optional PDF attachment to the “order completed” email. * **Admin control**: metabox on every order with Generate / Regenerate / Download. * **Secure storage**: invoices live in a protected uploads folder with unguessable file names and are only served through authenticated endpoints. * **HPOS compatible** (High-Performance Order Storage). * **No external calls, no tracking**: everything is generated locally on your server. #### Compliance notes * Invoices embed the CII XML at the **EN 16931** profile of Factur-X 1.x, validated against the official XSDs before the PDF is written. * Invoice numbers are sequential and gap-free; a number is only consumed once the invoice files have been written successfully. * On uninstall, the plugin removes its settings but **keeps generated invoices**: French law requires you to retain them for 10 years. #### Limitations of this version * The SIRET/VAT checkout fields are only added to the **classic (shortcode) checkout**. Stores using the block-based checkout still get automatic invoices, but the two B2B fields are not shown there yet — block checkout support is planned. * Refunds do not produce credit notes (avoirs); the original invoice is kept unchanged, as required (an issued invoice is immutable). * One VAT category per order line (standard/zero). Margin schemes, VAT exemption reasons and non-EUR specifics beyond currency code pass-through are not handled. * PDF/A-3 conversion covers embedded file relationships, XMP metadata and output intents as produced by the bundled Factur-X writer; full ISO 19005-3 conformance of exotic source PDFs is not re-verified at runtime. ## Screenshots [⌊Settings: seller identity, legal mentions, numbering and generation trigger.⌉⌊ Settings: seller identity, legal mentions, numbering and generation trigger.⌉[ Settings: seller identity, legal mentions, numbering and generation trigger.

Upload the plugin to `/wp-content/plugins/` or install it through the WordPress plugin screen. 2. Activate it (WooCommerce must be active). 3. Go to **WooCommerce OuiFacture** and fill in your seller identity (raison sociale, SIRET, n° TVA, adresse…). These appear on every invoice. 4. Choose the trigger status (default: processing). Done — invoices now generate automatically. ## FAQ ### Is this the format required by the French reform? The plugin produces Factur-X PDF/A-3 invoices with an embedded EN 16931 CII XML — the mixed format retained by the French reform. Transmission through a Plateforme de Dématérialisation Partenaire (PDP) is not included in this version. ### Where are my invoices stored? In `wp-content/uploads/ouifacture/`, protected by an `.htaccess` deny rule and random file names. Downloads always go through authenticated endpoints. Note: the `.htaccess` rule only applies to Apache/LiteSpeed servers — on nginx, add a `location` deny rule for that folder to your server configuration (file names remain unguessable either way). ### Can I regenerate an invoice? Yes, from the order screen. The invoice number and date never change on regeneration( a French invoice number is immutable); only the document content is rebuilt. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “OuiFacture – Facture électronique Factur-X for WooCommerce” is open source software.
