Budgeting role in public funds managements has become an integral part of public organisations. This study assessed the role of budgeting in the management of public funds in tertiary institutions using University of Energy and Natural Resource, Sunyani. The study adopted a case study research design using cross sectional survey methods. Stratified sampling and simple random sampling were used to select 244 respondents for the study. Data collected were analysed using descriptive statistics, frequencies, means, and standard deviation. Findings of the study revealed that Government funds are the main sources of funds at the university followed by internal generated funds. The study further established that, zero-based budget, participative budget and flexible budget are used at the university. The study concluded that budget preparation and implementations do not have challenges. The study again concluded that budgetary control practices such as budget practices, regulatory framework and auditing practices have effect on public financial management at the university. The finding again revealed that there is budget planning and development, budget implementation and budget monitoring and control at the University. The study recommended that the university should explore and identify potential financial resources within the university to augment government funding. It further recommended that managers at the university should improve on budget forecast estimates and avoid delays in approving budget by the executive board. This study suggests that a replica of the study should be conducted in most tertiary institutions in Ghana to give more national outlook for generalization.
