Abstract: Nowadays, the competitive environment of e-services companies has made them deliver high quality of services. In fact, the perceived quality of e-services by consumers which determines their behaviour towards products is defined as product acceptance. Consumers have a powerful potential to pass their experiences to other consumers. In this regard, this study intends to detect the rules determining the behaviour of consumers in product acceptance based on the perceived quality of e-services. Accordingly, 407 questionnaires were distributed among online retailers' consumers and then grey rough set theory was applied to analyse them. Perceived quality dimensions and net promoter score (NPS) were determined as the condition and decision attribute, respectively. Finally, the six rules determining the behaviour of consumers were extracted through the data analysis process. Furthermore, the results showed that efficiency, system availability, fulfilment, responsiveness, and contact are the most important factors determining product acceptance.
