The subject of the thesis is the improvement of business processes by introducing a system for the electronic interchange of documents, with a special emphasis on the electronic interchange of documents. The paper analyzes how digital technologies and business information systems transform business processes and facilitate document management within organizations. Digital technologies are defined as tools and systems that use digital data for various business activities. Throughout history, their development has brought various types and forms of technologies that are now being integrated into business operations to improve efficiency and productivity. Business information systems represent key components for managing information and processes within the company. Their integration with digital technologies enables better resource management, faster data processing and easier communication and collaboration within the organization. However, implementing these systems comes with advantages and disadvantages that should be carefully considered. Electronic Document Interchange (EDI) brings numerous advantages such as speed, security and cost reduction, but also challenges such as system customization and ensuring data privacy. The paper analyzes the functionalities, advantages and protocols of the EDI system and their role in modern business. Analysis of data on document exchange was conducted to provide specific recommendations and research results based on a sample of respondents. A case study of the company INA is presented, which shows the situation before and after the implementation of EDI and predictions for the future. The goal of the paper was to investigate and present the impact of digital technologies and EDI systems on business, providing a detailed insight into their application and benefits. The research was conducted on a sample of 105 employees of companies that use electronic document exchange. The results show how digital technologies and EDI systems significantly improve business processes, but also highlight the importance of careful planning and implementation of these systems for maximum benefits.
