Marketing and sales differ greatly, but they generally have the same goal. Selling is the final stage in marketing which puts the plan into effect. A marketing plan 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 of the products and services to the customer and increasing the number and engagement of successful 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. It can also include encouraging the potential customer to visit the organization's website, contact the organization for more information, or interact with the organization via social media channels such as Twitter, Facebook and blogs. Social values 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 is the process of persuasion and effort from one person to one person (B2C), or one person to a corporation (B2B), in order to make a living resource enter the company. This may occur in person, over the phone or digitally.
