Validates EU business VAT numbers live against VIES in the cart and cart drawer, then removes VAT automatically under the EU's cross-border exemption rules — no Shopify Plus required. Removes the exact VAT Shopify already applied per line, so reduced-rate products stay correct. Every check writes a VIES consultation reference to the order for your records.

• 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
• Accepts VAT numbers with spaces, dots, or hyphens automatically
• Never falsely rejects a customer when VIES is temporarily down
