This paper explores the implementation of digital assistants in the banking and telecommunications sectors with the goal of automating business processes. Digital assistants bring significant advantages such as improved customer education, building long-term relationships, enhancing business results, and optimizing business processes. However, the implementation of these technologies faces challenges such as technical complexity, the need for organizational culture change, and compliance with legal and regulatory requirements. In the banking sector, digital assistants have proven useful in providing information about financial products and options such as "Buy now, pay later," while in the telecommunications sector, they have been used to educate users about tariffs and services through interactive games and quizzes. The integration of digital assistants in the banking system was hindered by a lack of continuous cooperation and team changes, whereas in the telecommunications sector, it was more successful due to excellent coordination and support from an "internal champion." The paper also includes case studies of the implementation of digital assistants in one of the leading banks in Croatia and in a telecommunications company, comparing the success of implementation between these two sectors. The research results indicate the importance of careful planning, continuous cooperation, and openness to innovations for the successful integration of digital assistants into business processes.
