Del credere agent guarantees purchaser solvency and acts as surety, creating contingent liability to indemnify the principal. A del credere agent is a mercantile agent who, for extra remuneration, guarantees the solvency and performance of purchasers to the principal; by charging a del credere commission the agent assumes a surety-like obligation that arises on purchaser default, creating an indemnity-type responsibility distinct from ordinary brokerage duties. A factor is an agent entrusted with goods for sale who, when acting as a del credere agent, accepts additional credit risk and liability to indemnify the principal for losses from credit extended to third parties.
