A multi-tenant B2B customer-approval and wholesale-pricing app for Shopify, live in the Shopify App Store. Merchants run tiered pricing, custom registration forms (license #, tax ID, business documents), and automated approval workflows. Shopify Functions in the extensions workspace enforce purchase restrictions and apply wholesale discounts server-side, so unapproved customers can't reach checkout. Built on the Shopify App React Router framework with Prisma session storage. Marketing site at wholesaleharmony.com — App Store listing has a product video + screenshots.
