For Shopify Plus, collect and validate a VAT number in checkout. Supports all EU languages. 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.
