Today's most successful salespeople are much less talkative, and much more focused on listening and posing the right questions. For example, many attorneys cultivate new clients for years before they are given an assignment. Secondly, ask for references. Third, consider the potential return on investment when you weigh the cost of the program. And you need to provide coffee or food.
Some companies do the training off site which requires payment for a hotel room.
Other companies even fly in employees from remote locations, and all those things add to the real cost of the program. If you increased your sales only a modest few percentage points, most companies would be able to pay for the sales training several times over. And the sales training will pay dividends for the foreseeable future, increasing the value of your investment. A person who fully understands business, and how the sales effort fits into the context of everything your company or organization is doing, can be the best help to you. Your trainer should have a background of serious and impressive accomplishment in assisting salespeople to improve their results, and you should like the trainer's personality.
