Business organizations around the world engage in e-commerce (EC) and e-business to support business
operations and enhance revenue generation from non-traditional sources. Studies focusing on EC
adoption in Sub Saharan Africa (SSA) are just beginning to emerge in the extant information systems
(IS) literature. The objective of this current study is to investigate factors impacting the acceptance of
EC in small businesses in SSA with Nigeria as an example. A research model based on the Diffusion of
Innovation (DIT) and the Technology–Organization–Environment (TOE) frameworks were used to guide
this discourse. Such factors as relative advantage, compatibility, complexity, management support, organizational readiness, external pressure, and IS vendor support were used to develop relevant hypotheses.
Questionnaires were administered to respondents in Nigeria and data analysis was performed using the
Partial Least Squares (PLS) technique. Predictions related to relative advantage, management support,
and IS vendor support were confirmed; the other hypotheses were unsupported by the data. The study’s
implications for research and practice are discussed in the chapter
