Commissions are a form of variable-pay remuneration for services rendered or products sold. Commissions are a common way to motivate and reward salespeople. Commissions can also be designed to encourage specific sales behaviors. For example, commissions may be reduced when granting large discounts. Or commissions may be increased when selling certain products the organization wants to promote. Commissions are usually implemented within the framework on a sales incentive program, which can include one or multiple commission plans.
