Sales representatives for manufacturers and wholesalers have long played an important role in the U.S. economy. By representing products and seeking potential customers, they have helped in the efficient distribution of large amounts of merchandise.
The earliest wholesalers were probably the ship "chandlers," or suppliers, of colonial New England, who assembled in large quantities the food and equipment required by merchant ships and military vessels. Ship owners found that a centralized supply source enabled them to equip their vessels quickly.
Various developments in the 19th century made wholesalers more prominent. Factories were becoming larger, thus allowing for huge amounts of merchandise to be manufactured or assembled in a single location. New forms of transportation, especially the railroad, made it more practical for manufacturers to sell their products over great distances. Although some manufacturers would sell their goods directly to retail outlets and elsewhere, many found it easier and more profitable to let wholesalers do this job. Retail stores, moreover, liked working with wholesalers, who were able to sell them a wide range of merchandise from different manufacturers and from different areas of the country and the world.
The sales representatives hired by manufacturers and wholesalers were typically assigned a specific territory in which to sell their goods. Armed with illustrated product catalogs, special promotional deals, and financial support for advertising, they traveled to prospective customers and tried to explain the important qualities of their products. Competition between sales representatives sometimes was fierce, leading some to be less than scrupulous. Product claims were exaggerated, and retail stores were sometimes supplied with shoddy merchandise. Eventually more fact-based sales pitches were emphasized by manufacturers and wholesalers, who in the long run benefited from having responsible, honest, well-informed representatives. Products also began to be backed by written guarantees of quality.
Meanwhile, some manufacturers employed door-to-door sales workers to sell their products directly to consumers. Direct selling in the United States goes back to the famous "Yankee Peddler" who, during colonial times, traveled by wagon, on horseback, and sometimes on foot, bringing to isolated settlers many products not easily available otherwise. A forerunner of the modern door-to-door sales worker, peddlers also tried to anticipate the settlers' needs and wants. They frequently represented new or unknown products with the hope of creating a demand for them.
Changes in the 20th century, once again including improvements in transportation, brought still more possibilities for sales representatives. Automobiles allowed representatives to travel to many more communities and to carry more product samples and descriptive catalogs. Trucks provided a new means of transporting merchandise. The growth of commercial aviation further expanded the opportunities for salespeople. Sales representatives would eventually be able to travel to customers in New York, Atlanta, Los Angeles, and Minneapolis, for example, all during a single week.
The U.S. Department of Labor lists durable goods merchant wholesalers as the largest employer of sales representatives (except technical and scientific products). Other important fields included nondurable goods merchant wholesalers, manufacturers, wholesale electronic markets agents and brokers, and retailers. Retail outlets needed a constant supply of clothing, housewares, and other consumer goods, and hospitals, which purchased specialized surgical instruments, drugs, rubber gloves, and thousands of other products from representatives.
