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
Metronome
Pros
Purpose-built for complex usage-based and hybrid pricing models
Trusted by major AI companies including OpenAI, Anthropic, Databricks, and Nvidia
Reduces engineering burden of building custom billing logic in-house
Strong investor backing and now backed by Stripe's infrastructure
Provides both invoicing and revenue reporting in one platform
Cons
No published self-serve pricing; requires a sales conversation
Primarily built for enterprise-scale usage volumes, less suited to very small companies
Implementation requires integrating usage event tracking into a company's product
Ownership transition to Stripe may change roadmap or standalone positioning over time
Best suited to usage-based models, so less relevant for simple flat-rate subscription businesses
