In this paper, we question the nature and dimensions of eValues. We apply our approach to electronic marketplaces (EMPs), as an illustration of interorganizational information systems. The research is based upon 50 interviews made in 6 EMPs, and a thematic analysis on the themes linked to “the value of EMPs”. Our results categorise the different perceptions of eValues according to the different profiles: the value proposition of EMPs’ managers and the perceived values of buyer and supplier managers. We highlight that eValue is a key component that helps to distinguish three types of EMP business models: the Buy-type, the Supply-type and the Indus-type. Finally, we discuss the orientation of each business model according to the current value it offers to customers, and conclude that the concept of eValue questions the design of the model of revenue of EMPs.
