Agency banking as a comparatively new model in Kenya has attracted attention from researchers due of the contribution it has towards financial inclusion. Lack of adequate finances has been identified as one of the challenges faced by MSMEs. Agency banking as an innovation seeks to mitigate the aspect of financial inclusion by taking banking services, which include but are not limited to provision of finance close to the customer. However, it is not conclusive as to what factors influence adoption of agency banking among potential customers. This led to the need to analyse possible factors that would affect adoption of agency banking. The first objective set out to analyse how perception influences adoption of agency banking whereas the second objective looked at social influence as a factor affecting adoption of agency banking. The research was descriptive targeting micro, small and medium enterprises in Nairobi County with special focus on Gikomba Market. Stratified Random Sampling was used and a structured questionnaire applied in data collection. The research findings concluded that social influence and perceived usefulness had a positive and significant impact on adoption of agency banking. The study recommends that there is need to have public participation through informative sessions as well as aggressive advertising and revamping of the agency model as a whole
