Enterprise resource planning (ERP) is a well-known business management system used for improving effectiveness in organisations. In the current digital era, cloud ERP systems have evolved which are taking precedence over the traditional ERP due to convenience of remote information access in real-time with benefits of cost saving, flexibility and scalability. These systems are especially helpful to SMEs which usually are constrained in resources. However, there have not been many studies that look at the critical success factors for cloud ERP adoption in SMEs. This paper develops an integrative framework using technology-organisation-environment (TOE) and unified theory of acceptance and use of technology (UTAUT) models to investigate the individual, environmental, technological and organisational levels of cloud ERP adoption in SMEs for identifying factors for success. The findings will provide new insights on cloud ERP adoption and will help both academia and practitioners increase understanding for future research and implementation
