Abstract: The purpose of the study was to explore the impact of electronic commerce on business performance with specific focus on business organisations in Harare, Zimbabwe. This was achieved through investigating the relationship between e-commerce investment and indicators of business performance such as cost operations, service operations and profit levels. A structured questionnaire was developed and administered to 40 respondents from 10 e-commerce organisations. The study revealed that there was a positive relationship between e-commerce investment and business performance. It was revealed that an investment in e-commerce by organisations in Zimbabwe would increase profit levels, improve service operations and reduce transaction costs. The researchers recommended that organisations that have already adopted e-commerce should raise customer awareness and interest in e-commerce and promote the usage of the technology. They also recommended that policy makers such as the Government must take a leading role in the funding of education and the development of infrastructure in order to encourage more organizations and consumers to participate in e-commerce.Keywords: E-commerce, Business performance, Business organisations, Service operations, Cost operations
