Stages-of-growth has been the most popular approach used for strategy development and implementation. The major stages of growth models such as Gibson and Nolan [1] have been widely discussed and are particularly useful in understanding the implementation of IS in organisations. These models might be more representative of e-commerce implementation, however, if they took into account more recent IS developments such as B2B ecommerce. Using a case study research undertaken in Australia, this study proposes a model of stages of growth based on the use of B2B e-commerce technologies and applications in Australian organisations. Four stages of growth proposed for B2B e-commerce implementation are (i) initial e-commerce; (ii) centralised e-commerce; (iii) looking inward for benefits; and (iv) global e-commerce.
