Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureGSTPro allows merchants to collect and validate customer GSTINs on the cart, side cart, and checkout before an order is placed. The app verifies GST registration details in real time and stores the verified GST information with cart and order data for use in billing and compliance workflows.
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.

- Track GST verification usage to monitor activity across orders
- Real-time VIES checks; unverified if VIES is down
