A substitute sales force refers to a group of individuals who are hired on a temporary basis to fill in for regular sales representatives in a company. These individuals are trained and equipped with the necessary knowledge and skills to effectively promote and sell products or services to customers. They act as a backup team, stepping in when the regular sales force is unavailable due to illness, vacation, or other reasons. The use of a substitute sales force allows companies to maintain a consistent level of sales and customer service, ensuring that no potential sales opportunities are missed. Additionally, substitute sales forces can provide a fresh perspective and new ideas, bringing a dynamic energy to the sales process.
