A sale is the process of providing products or services to potential customers in exchange for money. In the business context, the sales function is the key function that helps companies generate revenue and grow; it encompasses all activities aimed at selling manufactured products and satisfying consumers’ needs. Sales are planned in advance and market research is conducted. A sale is considered completed when a sale and purchase agreement is signed or an invoice for a specific product or service is received. There are different ways in which sales can be organised, and the organisational structure is simple in smaller companies, while larger companies require more complex organisational structures with multiple levels of hierarchy. Types of organisational structures include functional organisational structure, product sales force organisational structure, geographic organisational structure, multipurpose organisational structure and customer sales force organisational structure.
