VAT Engine

VAT Engine is an EU VAT calculation and compliance platform for developers, ecommerce businesses, SaaS products, and headless commerce.

It provides API access and a web dashboard for calculating VAT, working with current and historical VAT rates, classifying products, tracking transactions, monitoring OSS exposure, and preparing VAT compliance data.

Key capabilities include:

• EU VAT calculations
• Current and historical VAT rates backed by official EU data
• Merchant-friendly product tax classes
• VAT-inclusive and VAT-exclusive price calculations
• OSS and IOSS compliance workflows
• SME VAT threshold data
• Transaction history and audit evidence
• Multi-store and multi-channel reporting
• Shopify integration
• API access for headless checkouts, SaaS billing, and custom ecommerce integrations
• API key management and account security

VAT Engine is designed for developers and teams that want to integrate EU VAT logic without maintaining country-by-country tax data and compliance infrastructure themselves.
