Clients might include manufacturers, government agencies, and wholesale and retail businesses. Representatives study sales information and write reports. They also make appointments and travel plans, and keep expense account records. Depending on the type of employer, these sales workers may have different titles. For example, people who work for manufacturers are usually called manufacturer's representatives.
Sales representative is usually the title for people who work for wholesalers.
Wholesalers buy large amounts of a product from the manufacturer. They then sell it in smaller amounts to their customers. People who sell technical products for both wholesalers and manufacturers are called industrial sales representatives or sales engineers. These engineers have a technical background or a college degree in engineering. Manufacturer's agents are self-employed and usually contract their services to several companies.
