Do opposites attract? Assimilation and differentiation as relationship-building strategies

In addressing the call for the application of learning from other domains to the sales context, our work integrates the optimal distinctiveness theory with the study of buyer-seller relationships. We conceptualize two main buyer-seller relationship-building strategies - a value-added differentiation strategy and a compatibility-based assimilation strategy - and present an integrative theoretical framework explaining how these two strategies can be leveraged in the business and personal domains to meet customer needs and improve sales performance. Using the theory, we reconcile conflicting findings on the use of similarities and differences between salespeople and customers in buyer-seller relationships. Our theoretical framework helps salespeople address the dynamic nature of dyadic relationships strategically in a way that promotes customer satisfaction, improves the firm's performance, and nurtures its competitive advantage.
