A commission (fee) is a payment made to an individual or organization for facilitating a service or transaction. This fee is often a percentage of the total amount involved in the deal, such as a sale or a contract. For example, real estate agents typically earn a commission based on the sale price of a property, rewarding them for their efforts in closing the deal. Commissions are common in various industries, including finance, sales, and marketing. They incentivize agents and brokers to perform well, as their earnings are directly linked to their success in generating business. This structure aligns the interests of the service provider with those of their clients.
