POS & Inventory Management System for Construction & Sanitary Supply Store (MERN)

The POS & Inventory Management System is a secure, real-time, shop-focused web platform built using the MERN stack (MongoDB, Express.js, React, Node.js). It is designed to automate the daily workflow of a construction-material and sanitaryware store dealing in products such as tiles, cement, jali, pipes, basins, fittings, and hardware supplies. The system replaces slow and error-prone manual billing and stock registers with a modern Point-of-Sale interface that performs instant cart calculations and generates uniquely numbered invoices. After each sale, inventory is updated automatically and logged to prevent stock mismatches. The platform implements Role-Based Access Control (RBAC) for Admin, Manager, and Cashier, ensuring secure access that mirrors real shop responsibilities. Passwords are encrypted using bcrypt, and login sessions are authenticated through JWT tokens, protecting all API endpoints. The system maintains complete sales history, invoice records, inventory movement logs, and employee activity audit trails, ensuring transparency and accountability. Interactive dashboards and reports visualize revenue trends, low-stock alerts, best-selling categories, and weekly sales performance, helping shop owners make data-driven business decisions. The system is also scalable, allowing future integration of features like barcode scanning, vendor purchase modules, multi-branch support, and PDF/Excel report exports without redesigning the core architecture.
