The job of the sales professional is to help each prospective customer make the decision about what is best for him or her.  You’re not to leave the choice to them, and you’re not to take the decision out of their hands with some manipulative trick.  You’re there to help the prospect through the process of consideration.

If you’re engaged with a prospect, chances are he or she needs what you have to offer, but sometimes what you sell isn’t what’s best.  In this case, don’t push the sale, but don’t let the exchange go to waste. Recommend that the prospect not buy from you while asking for recommendations from the prospect if he or she comes upon someone who could use your product or service.
