Supermarket billing & inventory system in C++ - Sell Project

Supermarket Billing System — Project Description The Supermarket Billing System is a C++-based console application designed to streamline daily retail operations for small and medium-sized supermarkets. It automates the entire billing process, manages inventory, applies relevant GST and discounts, and secures sensitive functionalities with admin authentication. Key Features Automated Billing: Generates itemized bills for customers, applying GST and discounts automatically to ensure accurate transaction totals. Inventory Management: Maintains product details including stock levels, enabling the admin to add, update, delete, or display product records. Stock is automatically updated after each sale. Admin and Buyer Modules: Features separate, menu-driven interfaces for buyers (to purchase items and view their bill) and admins (to manage products and view inventory). Secure Admin Access: Protects administrative functions through password authentication, thereby preventing unauthorized access to inventory management. Data Persistence: Leverages C++ file handling to store and retrieve product and transaction data, ensuring that information is consistent across multiple sessions even after the system is closed. User-Friendly Console Interface: Presents easy-to-navigate menus for buyers and admins, making it accessible for users with basic computer skills.
