Factella – French E-Invoicing for WooCommerce

From 1 September 2026 every French VAT-registered business must be able to receive electronic invoices, and from 1 September 2027 small and medium businesses must issue B2B invoices electronically and report B2C sales to the tax administration. Factella prepares small WooCommerce shops for that mandate.

• Adds optional SIRET and VAT number fields at checkout (block and classic checkout).
• Validates SIREN, SIRET and French VAT numbers.
• Numbers invoices and credit notes in one gap-free chronological sequence (PPF-compatible, max 20 characters).
• Creates an invoice when an order is paid or completed, and a credit note for every refund.
• Generates a Factur-X file for each invoice and credit note: a PDF/A-3 with embedded EN 16931 CII XML, including the French mandatory mentions and the 2026 national rules (BR-FR). Validated against the official FNFE-MPE validator.
• Uses the exact WooCommerce VAT rate per line, and handles standard VAT, mixed rates, reduced rates, shipping and fees.
• Covers the French exemption cases: franchise en base (VATEX-FR-FRANCHISE), intra-EU reverse charge (category K / VATEX-EU-IC) and export outside the EU (category G / VATEX-EU-G).
• Branded, French, human-readable PDF with your logo and accent colour.
• Attaches the PDF to the customer's order emails and offers a download from the customer account.
• Bulk generation and ZIP export for past orders, plus a wp factella generate WP-CLI command.
• Exposes the invoice data (read-only) on the WooCommerce orders REST API.
• Readiness check and a period report (B2B, B2C by VAT rate, refunds) with CSV export.
• Optional transmission of B2B / B2BInt invoices and credit notes to the SUPER PDP platform with your own SUPER PDP account (manual button or automatic, with status tracking). B2C sales are never transmitted — they belong to e-reporting.
• Looks up the company name from a SIRET at checkout against the French public business register.

Factella is an independent project and is not affiliated with or endorsed by WooCommerce, Automattic or the French tax administration (DGFiP).

0.3.0

• New: transmit B2B / B2BInt invoices and credit notes to the SUPER PDP platform with your own account (OAuth2 client_credentials). Manual "Send" button and opt-in automatic sending, queued with Action Scheduler and retried with backoff on transient failures.
• New: transmission status on the order screen and list (sent / accepted / rejected), polled periodically; clear French error messages (invalid credentials, company not verified, invalid invoice, rate limit, platform unavailable).
• New: SUPER PDP connection settings (sandbox / production, encrypted secret, "Test connection"), plus connection/verification/sandbox lines in the readiness check.
• New: company-name auto-fill from a SIRET at checkout via the French public business register (cached, rate-limited, non-blocking).
• B2C sales are never transmitted (they belong to e-reporting) and are shown as such on the order.

0.2.0

• Correctness: per-line VAT rate read from WooCommerce (not derived); fees added as invoice/credit-note lines; total reconciled to the order total via the rounding amount (BT-114); unit price with 4 decimals.
• VAT categories: intra-EU reverse charge (K / VATEX-EU-IC) and export outside the EU (G / VATEX-EU-G), in addition to standard, zero and franchise en base.
• Pre-generation EN 16931 validation blocks an inconsistent invoice.
• New: readiness check on the settings tab, and a period report (B2B / B2C by VAT rate / refunds) with CSV export.
• Logo can be picked from the media library; WP-CLI command renamed to wp factella generate.
