VAT Engine
EU VAT API for ecommerce, SaaS, and headless commerce
VAT Engine is an EU VAT calculation and compliance platform for developers, ecommerce businesses, SaaS products, and headless commerce.
It provides a REST API and web dashboard for VAT calculations, VAT rate lookup, product tax classes, VAT-inclusive and VAT-exclusive pricing, SME VAT thresholds, transaction records, and source-aware reporting.
Date-indexed rate lookup is available where recorded/imported history provides coverage. VAT Engine also includes OSS/IOSS preparation workflows, multi-store reporting, managed source profiles, and an alpha Shopify integration.
The product is currently available with free alpha access while the API, compliance workflows, and integrations continue to be validated.

Comments
I started VAT Engine because EU VAT becomes much harder once you move beyond a simple rate lookup. Developers end up dealing with product tax classes, transaction dates, multiple stores, OSS/IOSS workflows, and the need to understand later why a certain VAT result was produced. I’m building VAT Engine as a developer-first API and dashboard around those problems. It’s currently in free alpha, and I’m especially interested in feedback from developers and ecommerce teams using VAT in real integrations.
