SPSS and PLS-SEM using smart PLS was used to analyse the data. The study concludes that environment, attitude and normative structure adoption factors have significant influence on the adoption-use of the open source ERP. The findings indicate that, competition within the sector, internal facilitation through training and top management support can increase adoption and use. The findings reinforce the need to support new technologies from both managerial, technical and policy perspectives.
