Standard
Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCertly handles the entire lifecycle of US resale and exemption certificates. B2B customers upload a PDF from their account page; Certly extracts the key fields with AI, lets you approve or reject in one click, and marks the customer tax-exempt in Shopify. Expiring certificates trigger automatic renewal reminders, and stale ones expire on their own so you stop charging tax-exempt buyers by mistake.
Allow customers to validate their EU VAT ID and get tax-exempted in real-time. Add VAT IDs to existing customers from the Shopify Admin. Shopify Plus stores can integrate the validation module directly in the Checkout. Exemptify also facilitates international sales by displaying correct prices based on customer location, so your customers know right away what they will have to pay at checkout.
