E-commerce (EC) can be mainly divided into business-to-business (B2B) EC and business-to-consumer (B2C) EC. Given small and medium-sized enterprise (SMEs) mainly use EC applications to interact with their supply/business partners, distributors, wholesalers and retailers (e.g., Al-Qirim, 2007; Jennex, Amoroso & Adelakun, 2004), EC in the context of SMEs is mainly categorized as B2B EC (Ghobakhloo & Tang, 2011). In the current digital business environments, SMEs are increasingly engaging in B2B EC to develop a series of competitive activities to achieve performance improvement, sustainable competitive advantage, and opportunities to secure long-term success (Ghobakhloo, Arias-Aranda & Benitez-Amado, 2011). Although information system (IS) benefits/business value is a well-established IS research topic, there has been little research on how organizations evaluate their engagement in B2B EC and the extent to which they benefit from their investments (Standing & Lin, 2007). In addition, we still do not know whether investment in EC in B2B environments creates business value for SMEs. Likewise, we do not clearly know how to evaluate the success of B2B EC within these businesses. The lack of understating on the business value of B2B EC is more problematic for SMEs in developing countries. Organizational EC in developing countries has only recently gained attention in the academic press (Ghobakhloo, Sabouri, Tang & Zulkifli, 2011; Ghobakhloo & Tang, 2013). Research on EC value is even scarcer in relation to SMEs in developing countries. Given the limited understanding of B2B EC success within SMEs, particularly in developing countries, the aim is to address this gap by examining the dimensions of B2B EC success among Iranian and Malaysian SMEs.
