1, it can be described as an account manager. One company I worked for hired sales for a position that was called an account manager. I've heard salespeople say before that when they go to meet a customer, if they take out a business card with a salesperson on it, the customer really doesn't want to see you. By saying account manager, even though the company knows internally that they are not managerial, the salesperson does feel more confident when they go out to meet the client. The customer will also feel that the person who was sent to meet me is a manager not a regular salesperson, and the willingness to take the time to talk to them really helps to achieve sales goals.
2, There is also talk of a business development manager. Several years ago, a vendor sales, said he would bring his foreign colleague to meet me. After chatting, I learned that the foreigner was an ordinary salesman in their organization. When they left, I took a closer look and the position was business development manager.
3, there are even said to be the vice president of marketing. A friend who is a foreign banker has a business card that says VP of Marketing on the top. I asked her how many people and things she had to manage as a VP. She said she didn't have to manage people or things, just sales. As long as she can achieve sales results, everything is fine! The company gave her this title to help her achieve sales performance. She has her own way of doing sales, the title can help a little, their own ability is even more critical.
But in the example above, talking up the salesperson is predicated on the company agreeing.
