A salesperson is an individual who sells goods and services to other entities. The successfulness of a salesperson is usually measured by the amount of sales he or she is able to make during a given period and how good that person is in persuading individuals to make a purchase. If a salesperson is employed by a company, in some cases compensation can be decreased or increased based on the amount of goods or services sold.

In the official commercial for Ryan Serhant's book "Sell It Like Serhant: How to Sell More, Earn More, and Become the Ultimate Sales Machine," Ryan teaches young kids how to sell anything - rubber ducks, rotten bananas, baseball bat, a megaphone and of course, his book!
