Upselling is a sales technique whereby a seller induces the customer to purchase more expensive items, upgrades or other add-ons in an attempt to make a more profitable sale. While it usually involves marketing more profitable services or products, it can be simply exposing the customer to other options that were perhaps not considered.
Direct selling is the marketing and selling of products directly to consumers away from a fixed retail location. Peddling is the oldest form of direct selling. Modern direct selling includes sales made through the party plan, one-on-one demonstrations, and other personal contact arrangements as well as internet sales.
A person or organization expressing an interest in acquiring the offered item of value is referred to as a potential buyer, prospective customer or prospect. Buying and selling are understood to be two sides of the same "coin" or transaction. Both seller and buyer engage in a process of negotiation to consummate the exchange of values. The exchange, or selling, process has implied rules and identifiable stages.
Sales effectiveness refers to the ability of a company’s sales professionals to “win” at each stage of the customer’s buying process, and ultimately earn the business on the right terms and in the right timeframe.
