Culsin ‑ B2B Registration Form

Add a B2B registration form to your storefront without any coding required. Customers submit their company details and VAT IDs through a simple application form. Review all applications in a clean dashboard within your Shopify admin, then approve or deny with one click. The app validates EU, UK, US, and Canadian tax IDs against live government registries to ensure accuracy. When you approve customers, they're automatically tagged, set as tax exempt, and their VAT ID is saved to metafields. Custom fields write directly to customer metafields for additional data collection. Shopify Flow triggers and actions are built in, letting you automate the approval process in both directions. For Shopify Plus merchants, the app can auto-create B2B Company records when approving applications. Works on any Shopify plan.
