Résumé
Although customer loyalty has proved to be a powerful determinant of firms' profits, the drivers of loyalty in B-to-B relationships are still unclear. Recognizing that both interpersonal and interorganiza-tional level variables are needed to predict customer loyalty, the aim of this study is to investigate the combined effects of salespersons' relational behavior and organizational fairness in predicting customer satisfaction and loyalty. Results from a field survey in a B-to-B setting show that buyer loyalty is largely determined by the quality of the interpersonal relationship with the seller. Perceived fairness is central for building overall customer satisfaction and loyalty toward the supplier.
