This paper explores the design, architecture, and implementation of a desktop-based billing software application using VB.NET (Visual Basic .NET) within the .NET framework. The objective is to develop a robust, user-friendly system capable of managing inventory, generating invoices, and tracking transaction history for Small to Medium Enterprises (SMEs). The proposed system utilizes a three-tier architecture, separating the presentation layer, business logic, and data access layers to ensure maintainability and scalability. A local SQL database is employed for data persistence. The paper details the database schema, key code modules, and the rationale behind choosing VB.NET for Rapid Application Development (RAD) in business contexts.
