The micro finance policy, regulatory and supervisory framework released by Central bank of Nigeria (CBN 2005) has put the accountants, managers and players in the microfinance sector in Nigeria on gear so as to meet the requirement for minimum capital base, increased profit performance, better liquidity position, increased volume of deposits and effective customer?s service delivery. The main thrust of the policy frame work was to purvey credit to the poor and the low income group. However the recent CBN report (2011) on poor performance of MFBs has put the capacity of the banks on enquiry as to micro credit delivery. The extent to which the SMEs have benefited from the credit scheme of MFBs has not received much attention in the literature. The study attempted to evaluate the convenience at obtaining credit, adequacy of the credit supplied relative to demand, timeliness of credit to operation, and cost of credit as a component of total overhead to selected SMEs located in Osun state of Nigeria. Data were collected through Questionnaire administered on SMEs as well as the annual reports and accounts of the selected MFBs. Analysis of the data and hypotheses tested showed positive and significant relationship between microcredit delivery service of selected MFBs and SMEs performance. However most MFBs seem to be competing with the commercial banks in universal banking rather than the microfinance banking they were purposely established to undertake. This manifested in the hesitation of credit to SMEs for fear of repayment. The study is expected to be useful to policy makers and players in the micro finance sub sectors of the economy.
