Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureValidates EU business VAT IDs live against VIES in the cart and cart drawer, then removes VAT automatically under the EU's cross-border reverse charge. No Shopify Plus required. Removes the exact VAT Shopify applied per line, so reduced rates stay correct, and writes the VIES reference onto the order.
EU B2B merchants need a reliable way to verify VAT numbers. Manual checks do not scale, and valid numbers can fail later. VAT Validator Pro checks numbers live against VIES via a storefront cart widget, plus a checkout field on Shopify Plus. Only VIES-confirmed results count as verified. If VIES is down, numbers stay unverified -> checkout continues and VAT may still apply.
- Works without Shopify Plus — validates in the cart, not just checkout
- Removes the exact VAT rate applied per line, not a guessed standard rate
- Every check writes a VIES consultation reference onto the order

- Real-time VIES checks; unverified if VIES is down
- Optional tax-exempt sync (merchant opt-in)
