In this paper, we introduce the concept of preferred customer status, i.e. a buyer is awarded
preferential treatment of its important suppliers compared to their other customers. As there is
a lack of knowledge of what motivates suppliers to serve selected buyers better than others,
our research focuses on the suppliers’ evaluation of customers and how it can be influenced
by buyers. Based on social exchange theory, we provide a conceptual model which proposes
customer attractiveness, supplier satisfaction and knowledge of alternative customers as factors
influencing suppliers to award preferred customer status. Subsequently, a literature review
is provided to give an overview of the drivers of customer attractiveness, supplier satisfaction
and preferred customer status already analysed in current literature. We conclude by
providing a preliminary conceptual framework and suggesting future research directions in
this field. This article proposes new insights into supplier relationship management and offers
a state-of-the-art analysis as well as a theoretical base to this new research field
