B2B Onboard replaces manual wholesale signup with a structured application and approval workflow. Build custom forms with a drag-and-drop editor, embedded on the storefront through an app proxy with no changes to your theme code. On approval, the app creates the B2B company and customer account, checks VAT IDs, and applies the right tax treatment (EU/UK reverse charge or US resale exemption). Certificates are read automatically and mismatches flagged for review.
