Does marketing depend on sales? How?

Marketing and sales are interdependent. The company needs revenue to stay in business. It gets revenue through sales. A talented salesperson is his or her own marketer, identifying buying trends and tailoring sales pitches to the individual customer. This can be time-consuming, and it takes the salesperson away from the important job of making and closing sales. So the company may delegate the marketing function to a separate but obviously related department. In this case, sales may depend on marketing, but marketing depends just as much, if not more, on sales to a) make the money that funds the marketing department b) inform the marketing department what's going on in the market Marketing departments assist sales departments. Sales can get along without formal marketing departments, but not vice versa.

Sales is directly proportional to the success of your marketing initiative. Better your marketing so is your sale and vice versa. But selling is not a direct KRA of the marketing depertment.
