Facturette — Shopify app for French e-invoicing
A published Shopify app that turns every paid order into a legally compliant Factur-X invoice — a PDF/A-3 document carrying the EN 16931 CII XML inside it — and, on the paid tier, files B2B invoices to the merchant's certified platform (Plateforme Agréée). Built in .NET 10 / ASP.NET Core on Oracle with EF Core, shipped as a Docker container behind a Cloudflare Tunnel, with OAuth, Shopify Billing, GDPR webhooks and App Store review.
