Sales and related workers typically do not need postsecondary training, but many employers seek applicants with prior sales experience. Generally, workers in marketing and sales occupations try to interest customers in purchasing a wholesale firm's goods and assist them in buying the goods. Inside sales workers generally work in sales offices.. They are also increasingly performing duties such as problem solving, solicitation of new and existing customers, and handling complaints.
Technological advances and market forces are rapidly altering this industry. Even workers in small firms need to keep informed about new selling techniques, management methodologies, and information systems. Although many sales workers receive a base salary in addition to commission, some receive compensation based solely on sales revenue.
