Abstract
In this paper, the authors analyze 91 key account relationships and 206 ordinary supplier–buyer dyads regarding differences in suppliers' relational behaviors and customers' perceptions of relationship quality (satisfaction, trust, and commitment). The results suggest that while – as compared to ordinary relationships – suppliers put significantly more effort in “value-creating behaviors” in key account relationships, they do not modify their “value-claiming behaviors” in those dyads. On the customer side, suppliers' increased value creating activities lead to increased commitment. However, customers are neither more satisfied, nor do they trust their suppliers more when they receive key account status.
