Access to finance is an important factor for the sustainability and growth of business. Lack of finance means that, the business will operate under-optimal and cannot enjoy economies of scale. This article explores the difficulties of informal sector access to formal finance. The author offers means by which information and communication technology (ICT) can help bridge that gap. The study carried out asystematic literature review where several articles from Sub-Saharan Africa were reviewed. The findings show that access to finance is constrained by information asymmetry, lack of collateral, business informality, and bureaucratic procedures for accessing finance. ICT has potential to overcome these challenges by streamlining information flow, providing online collateral registration and reducing administrative processes for loan processing, disbursement and repayment. The findings suggest that, despite the big digital revolution in Africa, little has been done to align the digital world with the challenges of the informal sector.
