Pros & Cons
gofactox
Pros
Generates Factur-X invoices validated as PDF/A-3B compliant (146 of 146 verapdf rules) directly inside WooCommerce
Free Starter tier lets stores try manual invoice generation before committing to a paid plan
Compatible with WooCommerce HPOS and the block-based Checkout, plus WooCommerce Subscriptions, WPML and Polylang
No vendor lock-in — generated files are transmitted through the merchant's own Plateforme Agréée account (e.g. Iopole, Pennylane, Chorus Pro)
Cons
Interface and documentation are French-language only, which may limit adoption outside francophone markets
Only useful to merchants running WooCommerce — not a fit for stores on other e-commerce platforms
Automatic per-order generation, credit notes, and the REST API are gated behind the paid Pro/Business tiers
invoice-api
Pros
Covers a wide range of EU e-invoice formats (XRechnung, ZUGFeRD, Factur-X, FatturaPA, Peppol) from a single API
Free tier with no credit card required, plus a live API playground for testing before committing
Pre-built integrations for major shop platforms (Shopify, WooCommerce, Shopware, Magento, PrestaShop, JTL-Shop) and automation tools (n8n, Zapier, Make, Airtable, HubSpot)
Includes GoBD-compliant archiving with 10-year retention, addressing a compliance need many teams would otherwise build separately
Transparent, published self-serve pricing with a 14-day trial on paid tiers
Cons
Free tier is limited to 20 API calls total, which only covers basic evaluation, not real usage
Paid tiers are metered by API call volume, so cost can scale quickly for high-volume invoicing
Site content is presented primarily in German with an English toggle, and depth of English documentation may lag the German version
As a developer API rather than an end-user application, it requires engineering effort to integrate rather than being usable out of the box by non-technical teams
