Most commonly we charge a percentage of the amount collected, on a contingency basis when the delinquent monies are collected. We charge between 33% and 50% of the amount collected as our fee. The smaller percentage is usually charged for larger and less delinquent accounts, the larger percentage for smaller and older accounts. Under this structure the debtor is instructed to send the monies  which are due to the our company. We deduct our fee and remits the balance to the original creditor once the debtor's check clears the bank.
