As customers' needs have changed rapidly, market orientation has become a more primary focus of marketing literature. This study explores the strategies market-oriented suppliers use to accommodate customer needs. In addition, because buyer-seller relationships proceed through phases characterized by distinct behaviors, this study explores the relationship between market orientation and accommodation strategies over the course of the buyer-seller relationship lifecycle. The results show that market-oriented firms use flexibility and relationship-specific adaptation as accommodation strategies. Also, three market orientation components (customer orientation, competitor orientation, and interfunctional coordination) relate differently to flexibility and relationship-specific adaptation during the relationship lifecycle. Finally, accommodation strategies significantly mediate the effects of the three market orientation components on customer satisfaction. Thus, market-oriented firms can satisfy their customers and avoid an overreliance on current relationships by emphasizing either flexibility or relationship-specific adaptations that correspond to the lifecycle of the relationship.
