Globally, many scholars view entrepreneurship as important to small business enterprises (SMEs) in general because it is critical to development. Small business development is of key concern in Uganda, because SMEs dominate the Ugandan economy. However, the entrepreneurial performance is very low; it is therefore in the interest of the country to increase performance of these enterprises. This paper develops a conceptual model to test how to increase entrepreneurial performance among small business enterprises in Uganda: Data was collected by means of personal interviews, approximately 2000 face-to-face interviews with the entrepreneurs. Results indicated that entrepreneurship capital, entrepreneurial knowledge and entrepreneurial capacity have significant implications for entrepreneurial performance.
