Marketing and sales differ greatly but generally have the same goal. Selling is the final stage in marketing which puts the plan into effect, which also includes pricing, promotion, place, and product (the 4 P's). A marketing department in an organization has the goals of increasing the desirability and value to the customer and increasing the number and engagement of interactions between potential customers and the organization. Achieving this goal may involve the sales team using promotional techniques such as advertising, sales promotion, publicity, and public relations, creating new sales channels, or creating new products (new product development), among other things. It can also include bringing the potential customer to visit the organization's website(s) for more information, or to contact the organization for more information, or to interact with the organization via social media such as Twitter, Facebook and blogs. Social values also play a major role in consumer decision processes. Marketing is the whole of the work on persuasion made for the whole of the target people. Sales are the persuasion and effort that from one person to one person (B2C), one person makes to the corporation (B2B) in the face or in the phone or in the digital environment, to make a living resource enter the company.
The field of sales process engineering views "sales" as the output of a larger system, not just as the output of one department. The larger system includes many functional areas within an organization. From this perspective, "sales" and "marketing" (among others, such as "customer service") label for a number of processes whose inputs and outputs supply one another to varying degrees. In this context, improving an "output" (such as sales) involves studying and improving the broader sales process, as in any system, since the component functional areas interact and are interdependent.
