Entrepreneurship and/or small business development has been noted as the bedrock of economic development of countries. Thus entrepreneurship capacity building is very paramount if entrepreneurs and/or owner managers can effectively contribute to economic development of countries, particularly countries of the developing world. This study examines entrepreneurship capacity building in Ghana with emphasis on the perspectives of owner managers. The major data collection tool was interview with 102 owner managers who were purposively sampled. The study revealed that the major enterprise support institutions engaged in building the capacities of owner managers are financial institutions, higher educational institutions, government agencies and/or international institutions. The study further revealed that small business owners have accessed facilities offered by the enterprise support organisations, mainly in the areas of management training and financial assistance as a way of building their capacities for growth and development. It was also discovered that these facilities have impacted positively on the activities of the owner managers. However, there are still some challenges the owner managers encounter in accessing these facilities. Some of the owner managers were not aware of these facilities provided by the enterprise support institutions. The owner managers were of the view that, the enterprise support institutions needed to do more than they are currently doing, particularly the government institutions, as their contribution to building entrepreneurship capacity has been negligible.
