    This research focused on the design and implementation of a responsive web application based on open-source frameworks for inventory and sales management at Don Llambo, a meat processing and distribution company located in the rural parish of Pilahuín. The study emerged from the need to modernize the company's operational processes, which were previously performed manually, leading to delays, frequent errors, and limited traceability in inventory control and sales record management. Data collection was carried out through a structured interview with the manager and Likertscale surveys administered to operational staff. The development process followed the Extreme Programming (XP) methodology through three iterations, enabling incremental progress and prioritizing key functionalities such as digital producto registration, JWT-based authentication, role-based access control, and automatic PDF receipt generation. The solution was developed using Angular 17 for the frontend, .NET 9 for the backend, and SQL Server on Azure as the database management system. This architecture allows users to access the system from any device equipped with a web browser without requiring local software installation. The results obtained from seventeen acceptance tests conducted with company personnel demonstrated a reduction in inventory reconciliation discrepancies compared to the previous manual process, as well as improvements in sales registration times. These findings validate the effectiveness of the proposed technological solution in addressing the operational challenges initially identified and contribute to improving the efficiency, reliability, and traceability of inventory and sales management processes.
