PurposeIn response to a turbulent industrial environment, especially for small and medium enterprises (SMEs), organizations have widely adopted e-business to improve their processes. This study aims to propose a model that encapsulates the determinants and outcomes of e-business adoption.Design/methodology/approachThe determinants and outcomes of e-business adoption were tested using data gathered from 282 managers and analysed using structural equation modelling techniques.FindingsThe results indicated that owner support, perceived ease of use and government support were important determinants that influence e-business adoption. Attitude, competitive pressureand relative advantage were not significant. Regarding outcomes, e-business adoption had a major impact on SME functioning and operational progress; however, it had no influence on competitive advantage.Originality/valueBy ascertaining the determinants and outcomes of e-business adoption, the findings provide e-business practitioners and managers with guidelines that can encourage more efficient and effective e-business adoption within their organizations. The results also provide a basis for more precise e-business studies to be conducted in developing countries.
