The purpose of this study is to understand how interactions between structure and agency shape e- government portal development in developing countries and how these are managed to arrive at an outcome. The need for the research emerged from growing concerns that there are few studies addressing the pre-adoption stages of e-government portals. The research used the development of an e-government payment portal in Ghana as a case study. The structuration theory was adopted as the analytical lens. The findings show that technical and political interactions such as testing, expert reporting, design, and blurry as well as overlapping authority shaped expert validation, expert reporting, payment workflow, security and privacy structures. Although the case is based on the experience of Ghana, the findings can be applied to other developing countries with similar experiences. The study offers implication for research, practice and policy makers as well as future recommendations.
