## Overview

This is a Next.js wholesale-commerce and business-operations application: it combines a public product catalogue and enquiry entry points with administrative and sales workspaces for leads, orders, warehouse dispatch, and invoicing. The sampled code shows server-side route handling, shared persistence, tax calculation, and invoice-document generation. The README is only the generic Next.js starter, so capability details and most page-to-endpoint relationships come from the repository tree; those connections are not asserted where no relationship was shown.

Main entry points: [`src/app/api/leads/route.ts`](https://github.com/pratik0192/makextrab2b/blob/main/src/app/api/leads/route.ts) (Lead intake), [`src/lib/prisma.ts`](https://github.com/pratik0192/makextrab2b/blob/main/src/lib/prisma.ts) (Application database), [`src/app/api/admin/products/route.ts`](https://github.com/pratik0192/makextrab2b/blob/main/src/app/api/admin/products/route.ts) (Product API), [`src/lib/invoices.ts`](https://github.com/pratik0192/makextrab2b/blob/main/src/lib/invoices.ts) (Invoice operations)
