This paper describes the main challenges encountered in the development and testing of an Integrated Digital Commerce System, designated Luna, an innovative solution that combines a mobile e-commerce application (m-commerce) with a web-based commercial management application. The developed system utilizes the agile Scrum methodology and adopts a three-layer architecture, relying on technologies such as PostgreSQL, Node.js, Express, React.js, and Flutter. Functional and usability tests were conducted to correct and anticipate system failures. The integration of IBM Watson into the navigation of the mobile application was particularly well received, as the Watson Assistant proved capable of understanding users’ questions and providing relevant answers. The test results demonstrated the effectiveness and efficiency of the platform, highlighting its potential to drive e-commerce and improve commercial management for small and medium-sized enterprises.
