POS System

A cross-platform point of sale desktop application built for retail stores using Electron.js, enabling offline-first operation with background sync to a Django REST Framework backend. Store staff use it to process sales, manage inventory, and print receipts without requiring a constant internet connection.

The app includes a comprehensive reporting module for daily sales summaries, top-selling products, and cashier performance. End-of-day reconciliation compares cash drawer totals against system records, flagging discrepancies for review.
