The commission section is where you are able to tell what commissions need to be paid to your sales team. The commission is calculated based on the amount of commission ($) given to each individual product or service in the product catalog and the percentage % assigned to the employee or user. In this section you have a historic of paid or pending to be paid commissions for a period of time.
