mahmoudalfalah/pos-erp-system ? reverse-engineered prompt

Build me a full stack POS and inventory management app for a small business.

I want a clean dashboard where I can track products, stock levels, sales, and basic business data in one place. The app should let me add and edit items, record purchases and sales, see what is low in stock, and view simple summaries that help me understand what is happening in the store. Keep the interface modern and easy to use, with a polished admin style.

Use Next.js, TypeScript, Prisma, PostgreSQL, Tailwind, and shadcn/ui. Make the code feel well organized and type safe, since this is meant to grow into a bigger ERP style system. Set it up so the main flows work end to end, with sensible sample data if needed, and make sure it runs cleanly in development. If you need current details from the docs or best practices, look them up online first.
