Salespeople are the principal vehicle through which B2B firms, particularly firms with a complex and differentiated offering, communicate and exchange information with their customers. Wotruba (1991) identifies the following roles for salespeople within a firm’s marketing program: (1) informer; (2) persuader; (3) problem solver; and (4) value creator. This chapter focuses on the different sets of knowledge, skills and abilities required by salespeople in the various roles.
