Electronic Commerce is concerned with conducting business transactions electronically using information and communication technologies. In this globalization era, many organisations in various countries have rapidly adopted e-Commerce to enable efficient trading with other organisations located in various parts of the world. However, e-Commerce adoption is still unilaterally concentrated in developed countries which are attributable to some issues related to the relevance of e-Commerce for organisations in developing countries. Currently, there are limited detailed studies into the adoption of e-Commerce technologies in developing countries. Therefore, in this study, we conducted a multiple case study over an extended period of time, exploring the adoption of e-Commerce technologies that support business-to-business interactions within the supply chain of the grocery industry in Indonesia, as an example of a developing country. Valuable insights have been obtained regarding the adoption of e-Commerce technologies by the participating organisations in Indonesia to better manage their supply chain. This study offers important implications to both academics and practitioners in the field of technology adoption
