Sales and marketing are two business functions within an organization -- they both impact lead generation and revenue. The term, sales, refers to all activities that lead to the selling of goods and services. And marketing is the process of getting people interested in the goods and services being sold.

Marketing informs and attracts leads and prospects to the company and product or service. Sales, on the other hand, works directly with prospects to reinforce the value of the company's solution to convert prospects into customers. While these two business functions are different, they both share a common goal: to attract prospects and convert them to customers, ultimately generating revenue.
