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.
Tax Exempt Manager automates B2B sales tax exemption certificate handling for U.S. wholesale merchants. Customers submit certificates through a branded storefront portal. Merchants review, approve, or reject from a dedicated admin dashboard. Approved certificates automatically sync tax-exempt status to customer accounts. AI-powered OCR extracts certificate data from uploads, eliminating manual entry.
- Self-serve cert upload in the new customer account no email back-and-forth

- Branded storefront portal for customer certificate submission
- AI-powered OCR auto-extracts data from uploaded certificates
- Auto-sync tax exemptions directly to Shopify customer accounts
