Outsourcing has become an accepted business practice because it can deliver demonstrable savings and improved services. However, while sales outsourcing is common, it has not been widely adopted by companies accustomed to having dedicated in-house sales staffs. Authors Erin Anderson and Bob Trinkle make a powerful case for the benefits of using outside sales reps, asserting that they cost less and sell more, particularly when they use the tactic of "portfolio selling." The authors explain how the two types of sales forces can co-exist and augment each other. Diehard sales managers will find interesting material here, though the book belabors a few obvious points and lacks enough real-world examples to juice up the dry text. The authors include a CD with software for analyzing sales costs. Since this is a very specific book for anyone investigating whether to use reps, recommends it to sales directors and executives who are facing that question. However, front line salespeople and reps should just keep to their appointment books - this text is not designed for you.

  • How to compare the costs of an in-house sales staff versus outsourced sales reps;
  • What are the benefits of "portfolio selling;" and
  • How a rep sales team and an in-house sales force can co-exist productively.
