This paper examines capacity building from the perspective of business growth and success in small-scale agro-processing enterprises. Our analytical approach was underpinned by the inability of small-scale agri-enterprises to grow and succeed despite the South African government's support for capacity building through the economic empowerment programme initiative in the past three decades. The study was conducted in five of nine selected South African provinces (Gauteng, Limpopo, North-West, Free State, and Mpumalanga). This study was essential for developing an effective strategy for enhancing agri-business growth and success in South Africa. A concurrent mixed-methods research design was used, and data from 503 small-scale agro-processors was analysed using descriptive and multiple regression analysis techniques. The results revealed that capacity building (β = 0.274, p = 0.000) significantly influences the economic empowerment of small-scale agro-processors. Furthermore, the study showed that mentorship and technical and financial skills are critical types of capacity building that influence the economic empowerment of small-scale agro-processors in South Africa. It is recommended that all government or private stakeholders, including agricultural extension advisory services, invest in capacity-building programmes for small-scale agro-processors to achieve economic empowerment. Economically empowered small-scale agro-processors will significantly contribute to employment creation and better income distribution.
