Abstract: This research provides important extensions to the Technology Acceptance Model (TAM) with system quality considerations (Q-TAM) in the context of e-procurement services. Utilizing data from organizational buyers and founding our expectations in the resource-based view, coupled with the dynamic capabilities perspective, we study the impact of information flow quality and logistics fulfillment quality on organizational buyers' perception of e-procurement services, and the ensuing intentions to continue using these services. As such, this study addresses user satisfaction as an attribute to understand organizational buyers' continuance intentions of e-procurement systems in a mandated usage setting. Furthermore, the mediating roles of individuals' perception in the relationship between system characteristics and satisfaction are investigated. We distinct our work with prior literature on e-procurement by focusing on organizational buyers' continued usage intentions, rather than investigating the e-procurement adoption issues at the firm level. Also, our research is positioned in a unique context since it investigates a system that is generally mandatory in nature. While a system may have been implemented successfully and its use may have been mandated, it may actually not be used to its fullest extent, leaving significant potential unrealized. Overall, with our theoretical development and the empirical test of Q-TAM, we provide important insights into organizational buyers’ intentions to continue the use of e-procurement services.
