Small and medium enterprises (SMEs), which account for 96% of businesses in Nigeria are often forced to close because they lack access to funds. The purpose of this multiple case study was to explore the sources of funds available for the development and growth of SMEs in Nigeria. The conceptual framework guiding this study was the pecking order theory. Data were gathered from company documents and through semistructured interviews of a target population of 3 leaders of 3 SMEs from the oil and gas industry in Abuja, Kano, and Lagos in Nigeria, with a capitalization of between N5 million to N500 million. Data were compiled and organized, disassembled into fragments, reassembled into a sequence of groups, and interpreted for meaning. Member checking and triangulation of sources between the interviews and company documents added to the trustworthiness of the findings. Two themes morphed from the study: sources of business finance for SMEs and constraints of sourcing of finance for business. The implications for positive social change include the potential to create employment opportunities for youths in the communities by enabling SMEs in Nigeria to succeed and expand through the identification of sources of funding.
