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 integrating EU VAT logic into custom checkouts, billing systems, ecommerce platforms, and internal tools.
Key capabilities include:
Developers can create an account, generate an API key, and connect VAT Engine to headless storefronts, SaaS billing flows, ecommerce integrations, or custom applications.
The goal is to provide one developer-friendly VAT layer without requiring teams to maintain country-specific VAT rates, tax rules, reporting logic, and compliance infrastructure themselves.
