Research on relationship management has extolled the virtue of sellers creating value for their customers. Indeed, loyal relationships, defined as repeated business exchanges, tend to flourish when firms create and deliver value to their customers. While few argue this premise, questions remain regarding the precise delineation of a firm's value creation competence and the mechanism by which it influences the firm's performance. In the current study, the authors define the value creation competence concept and find empirical evidence for its positive effects on firm sales performance (e.g., new customer leads, close rates, retention, revenue, etc.). Interestingly, the results suggest this effect is mediated by strategic account management and the perception of the relationship held between buyer and seller. Both of these findings have implications in establishing that a firm's value creation competence translates into improved sales performance, mediated by strategic account management and relationship perceptions
