Billing System

The Billing System is a desktop application designed to automate the process of generating, managing, and tracking customer bills and invoices. Developed using C# Windows Forms and integrated with Entity Framework and SQL Server, the system ensures fast, reliable, and secure billing operations.

The system enables users to add products, manage customers, calculate totals, apply discounts, and generate detailed invoices. It also maintains transaction history and supports exporting reports for accounting and auditing purposes. Core database operations are handled efficiently through stored procedures to improve performance and data consistency, while Entity Framework ORM simplifies data access and reduces boilerplate code.
