A POS system is the backbone of any retail or service business. I built a full-featured POS application that handles everything from product management to real-time sales reporting.
Core POS Features
The system includes a barcode scanner integration, product catalog management, customer records, and an intuitive billing interface. Built with React for the frontend and Node.js + PostgreSQL for the backend, it handles high transaction volumes with ease.
Inventory & Reporting
I integrated real-time inventory tracking that automatically deducts stock on each sale and triggers low-stock alerts. The dashboard provides daily, weekly, and monthly sales reports with visual charts powered by Firebase for live data sync.
