In real terms all sales persons right from the Sales Man to President (Sales) are the Sales Representatives who have divided their roles in different capacities but going to the markets and facing the customers is every ones responsibility.  It is important to get the feedback from the horse mouth directly which is normally helpful in correcting the strategies made by the Sales Manager.

Is it for the prestige, that sales rep is called Sales Manager with business customers, while he remains a sales rep or sales executive in the consumer market. Its the verstality of sales section which determines individual designation.Designation comes with experience and skill.

Everyone in the company is a frontliner aiming to boost profitability at all times. Business decisions are made by managers but direct dealings are made by all so that there is no downtime on the part of the customer to be provided with services as soon as their legitimate inquiries and concerns are received. Even a janitor can lift up the phone once a call comes in.
