This book critically reviews accessibility of funding by Small to Medium Enterprises as a means to the enhanced sustainability of SME development in Botswana. Lack of access to adequate funding is cited as a global impediment to SME growth and development. Research output that reviews the SME funding challenge in a comprehensive fashion with a view to providing a magic potion for the enhancement of SME growth & development is also scant. This book contributes to the bridging of this knowledge gap. Traditional methods of funding SMEs are herein critically reviewed and emerging funding models as a possible panacea to SME access to finance are also discussed while a hypothetical Whole Entrepreneurial Package Model (WEP) is finally proposed.
