EUVAT.app – B2B Reverse Tax

Validate EU VAT numbers and apply reverse-charge VAT automatically for B2B transactions.

EUVAT.app automates VAT handling for cross-border B2B transactions within the EU. Designed for stores where VAT is included in product prices, it recalculates net prices for eligible EU businesses using the reverse-charge mechanism based on the buyer’s country. It validates VAT numbers via the VIES, shows exemption status in customer profiles, and removes tax when applicable. Works with modern and legacy accounts, as well as Themes v. 2.0 and 1.0. Easy to install and supports all EU languages.

• Customers submit VAT numbers directly from their account page
• Real-time validation via the official VIES system
• Automatically removes VAT from prices that include tax ("gross prices")
• Dynamically adapts to the buyer’s country-specific VAT rate
• Sends merchant alerts and flags invalid or risky VAT numbers
