The role of salespeople in industrial servitization: How to manage diminishing profit returns from salespeople’s increasing industrial service shares

Business-to-business companies often differentiate themselves from competitors by complementing goods with services. While extant literature on servitization points to substantial benefits for companies and underscores the importance of the sales force for successful servitization, it has rarely empirically investigated the negative effects of and barriers to effective selling of servitized offerings at the salesperson level. Drawing on transaction cost theory, we propose that with rising service shares, the specificity of offers and transaction costs grow, partially offsetting the financial benefits. We derive four salesperson factors that moderate the effect of salespeople’s industrial service share on salespeople’s profit. These factors pertain to the extent to which salespeople individualize offers and effectively manage offers’ specificity (adaptiveness, customer valuation skills, experience). We test our conceptualization with data from 220 salespeople and company records. The results are robust to endogeneity and show that service share has a diminishing positive effect on salesperson profit. While salespersons’ offer individualization enforces this harmful effect, salesperson adaptiveness and customer valuation skills show beneficial moderating effects. This study provides valuable insights for researchers and managers into the role of the sales force in servitization and into salesperson factors conducive to realizing the full profit potential of servitized offerings.
