Academically, selling is thought of as a part of marketing, however, the two disciplines are completely different. Sales often forms a separate grouping in a corporate structure, employing separate specialist operatives known as salespeople (singular: salesperson). Selling is considered by many to be a sort of persuading "art". Contrary to popular belief, the methodological approach of selling refers to a systematic process of repetitive and measurable milestones, by which a salesperson relates his or her offering of a product or service in return enabling the buyer to achieve their goal in an economic way.
Professional Selling is defined as "The holistic business system required to effectively develop, manage, enable, and execute a mutually beneficial, interpersonal exchange of goods and/or services for equitable value."
