Influence and persuasion are not the same thing. Influence is subtle and contributory, while persuasion is coercive pressure. Top salespeople give customers relevant information tailored to their needs, not force a viewpoint. Theodore Levitt's rule: sell the hole, not the drill.

Many marketers and salespeople conflate influence with persuasion. Influence is about having a contributory effect upon the thinking and actions of others without the apparent use of force. Persuasion, on the other hand, is about coercion. It's exerting pressure to get someone to do what you want them to do. It's a blunt instrument of last resort that salespeople use when they don't understand how to influence customer choice. The best salespeople are not trying to persuade someone to come to their point of view. They're giving customers relevant information affecting the purchasing decision, based upon what they understand to be the most important considerations for the buyer. As Theodore Levitt said, "Sell the hole, not the drill." Salespeople who believe their role is to persuade customers to buy are still selling drills instead of holes.
