Small and big sugar companies are striving towards achieving a competitive advantage over rivaling companies in the sugar business market. The principles of corporate governance; transparency, accountability, responsiveness, equity and inclusiveness abound the different processes and how every company handles its competitive advantage in the sugar industry. Kenya’s sugar industry performance has deteriorated from being the largest sugar producer in the region, to an importer of the same commodity. While there exist studies on the role of corporate governance, the inadequate findings prompted the study to further analyze the effects of accountability on the competitive advantage of the sugar industry in Kenya. Data was collected using questionnaire targeting 210 management staff of Mumias and Nzoia Sugar Companies. The study established that corporate practices positively affect competitive advantage at slightly above average (43.2%). The findings indicated that accountability significantly influenced service delivery at Mumias and Nzoia factories. The study recommends that sugar factories should work more in enhancing the corporate practices and meeting the needs and desires of the stakeholders, citizens included.
