ShipAnvil is a robust SaaS starter kit designed for Symfony 7.4 LTS, providing essential components that are often tedious to develop and costly if mishandled, all pre-configured, tested, and well-documented. It includes features such as authentication with compulsory email verification, magic links, and TOTP two-factor authentication with backup codes, along with a unified payment-provider interface supporting both Stripe and Lemon Squeezy, complete with hosted checkout, customer portal, and an offline sandbox environment. Additionally, it offers signature-verified and replay-protected webhooks that are processed asynchronously, a multi-tenant organization system with roles and invitations, and a Doctrine filter that tailors each query to the active tenant. There is also an administrative dashboard that tracks estimated Monthly Recurring Revenue (MRR) and churn rates, along with a Claude AI module that enforces quotas based on subscription plans. Furthermore, the solution includes a framework-agnostic EN 16931 e-invoicing engine (Factur-X, PEPPOL BIS) that has been validated through continuous integration by the recognized KoSIT and OpenPEPPOL validators. Users can deploy it easily with a Docker image and a VPS recipe, while supporting PHP versions 8.4/8.5, PostgreSQL 16+, and Tailwind v4, without reliance on Node.js or any build steps. The entire package is available for a one-time purchase, with the complete source code housed in a private GitHub repository, allowing for unlimited projects to be undertaken. This comprehensive offering ensures that developers can focus on building innovative features rather than dealing with the foundational setup.
