Desarrollo de Aplicación de Facturación Electrónica para Negocios Ecuatorianos mediante Una Solución Eficiente y Segura en .NET y WPF

Abstract

Abstract: This graduation project addresses the development of an electronic billing application for Ecuadorian businesses, implemented in .NET and WPF, targeted at small and medium-sized enterprises (SMEs) in the city of Quito. With the widespread adoption of electronic invoicing in Ecuador since November 2022, there was an identified lack of desktop applications that combine efficiency and security, thus meeting the local users' needs. The proposal consists of designing a technological solution integrated with an existing point of sale system, currently used by various restaurants, including the issuance, validation, and storage of electronic invoices in compliance with Ecuadorian legislation. This project emerges as a response to a policy of the Ecuadorian state regarding the mandatory issuance of electronic vouchers for all taxpayers. The justification focuses on the need for a desktop tool that promotes fiscal transparency, ensures the traceability of transactions, and supports the modernization of business management in the country. Technologies such as .NET 7, WPF, C#, MySql, and SOAP will be used, also incorporating XAdES Signatures to ensure data integrity and security.
