A person who earns extra commission for guaranteeing debts is called a del-credere agent. A del-credere agent is a type of commission agent who guarantees the payment of the debts of buyers to sellers. In other words, when a seller sells goods to a buyer on credit, a del-credere agent guarantees that the buyer will pay the debt to the seller. If the buyer defaults on the payment, the del-credere agent will pay the debt to the seller and recover the amount from the buyer with an extra commission. This extra commission is the main characteristic that sets a del-credere agent apart from other types of commission agents like a factor or a broker. Factors and brokers do not guarantee the payment of debts and do not earn extra commission for doing so.
