The fast expansion of online commerce offers opportunities as well as challenges to local businesses seeking to improve their market outreach. However, most SMEs encounter major obstacles, such as disjointed management systems and increased operating expenses. This research aims to address these issues by proposing a centralized platform that will enhance user experience, operational efficiency, and customer engagement. To achieve this aim, qualitative data were collected through interviews and observations of key stakeholders, including business owners, e-commerce specialists, and users of existing platforms. The findings demonstrate a clear need for an interface that is both user-friendly and customizable, in addition to centralized management and integrated payment systems to promote efficiency in operations. A prototype platform was developed and tested with regard to demonstrating significant improvements in usability and participant satisfaction. The research concludes that a customized multi-store e-commerce platform has the potential to greatly improve the operational capacities of SMEs, allowing them to compete favorably in the online market. Recommendations are made to business owners, developers of platforms, and policymakers on how to establish a conducive environment for the development of e-commerce in Uganda.en
