2. Commission (remuneration)The payment of commission as remuneration for services rendered or products sold is a common way to reward sales people. Payments often will be calculated on the basis of a percentage of the goods sold. This is a way for firms to solve the principal–agent problem, by attempting to realign employees' interests with those of the firm.
