A commission is a fee paid to an individual or organization for facilitating a sale or service. This payment is often a percentage of the total sale amount and serves as an incentive for salespeople or agents to promote products or services. Commissions are common in various industries, including real estate, finance, and retail. In many cases, commissions are structured to motivate performance, meaning the more a salesperson sells, the higher their earnings. This system aligns the interests of the salesperson with those of the company, encouraging them to work harder to close deals and increase revenue for both parties.
