EU VAT API for ecommerce and SaaS, with TEDB-backed rates, tax classes, date-aware calculations, and transaction evidence. Currently in free alpha; native commerce integrations are in development.
VAT Engine started with a practical question: how can developers keep EU VAT calculations consistent across countries, product types, dates, and checkout systems? We are building an API that connects rate evidence, calculations, transaction records, and compliance workflows. The product is independently developed in Germany and is currently in free alpha. Native commerce integrations, including Shopify, are in development. We share technical notes and welcome feedback from developers, founders, and finance teams.
Our stack
Go, PostgreSQL, Redis, Next.js, React, TypeScript, Docker, and GitHub Actions. The VAT API uses official EU TEDB source data. We write about API contracts, money arithmetic, transaction evidence, testing, and secure product development.
