Jobs for sales managers and seller in other words, requires in fact a huge the knowledge, skills and abilities. But despite the abundance of information on sales, for some reason is common belief that the work of the seller – it is unskilled labor. Therefore, if some young person does not good specialty or pronounced their own goals, etc., then he gets a job as a sales manager. Him, and not just him, it seems that this is an easy job. What is difficult? Customer calls, says he needed, the manager selects the desired commodity, agree terms and receives payment. Or is he calling someone and finds out – do not need any thing. But it just seems that everything is so simple.
And because it is rare to see a man which is a real professional in the field of sales. Professional practice differs from the sad sack, as well as the fact that a professional possesses all the necessary information and know how to use it. Incompetent same person just do not realize that there need any information. In this example a sales manager can be replaced by many other names of specialties, and the meaning is the same.
