The app stopped syncing after the last update and support took a week to reply. We lost orders during the outage and had to switch to a competitor.

About EUVAT.app – B2B Reverse Tax
EUVAT.app automates VAT handling for EU B2B transactions. It works with net or gross storefronts: when prices include VAT, the app reverse-calculates net by buyer country and applies reverse charge where eligible. VAT numbers are validated via VIES and re-validated on each transaction; the customer’s VAT status is stored and tax is removed when applicable. Supports EU/non-EU sellers, with or without OSS. For Shopify Plus, collect and validate a VAT number in checkout. Supports all EU languages.
Highlights
- VIES validation & reverse charge for eligible B2B orders
- Net & gross pricing support; auto net-from-gross by buyer country
- Collect & validate VAT at checkout (Shopify Plus only)
- Works for EU and non-EU sellers; supports OSS and non-OSS setups.
- Persistent customer VAT status; auto tax-exempt on future orders.
