There is a wealth of reporting and evidence from research that small third sector social enterprises have a vital role to play not just in relation to service delivery, but also contribute to nurturing positive relationships, supporting vulnerable, disadvantaged groups and building stronger communities (Maher, 2015a; Seanor & Meaton, 2007; Smallbone & Lyon, 2004). Most small third sector social enterprises are set up because they have identified a gap in the market. Often, this has meant that there is either a public-service or private-market failure. In order to help these enterprises grow, policy makers need to tailor policy and support aiming to build capacity of these organisations in terms of the scale and volume of their activities; to enhance their contribution at local, regional and national levels. Organisations should advance their business management and procurement skills to enable the creation of sustainable income. This chapter makes recommendations for both policy and practices to help the development, growth, and sustainability of small third sector social enterprises and concludes by making suggestions for future research opportunities.
