How do a commission agent in country A guarantee himself that an overseas seller from country B will pay him his commission on time when the Seller is paid by the overseas Buyer from country C?

A commission agent in country A can secure timely payment by establishing a clear contractual agreement with the overseas seller from country B, outlining the payment terms and conditions for the commission. Additionally, the agent could request a letter of credit or an escrow arrangement, which ensures that funds are set aside for the commission once the seller receives payment from the buyer in country C. This minimizes the risk of non-payment and provides a structured process for receiving the commission promptly.
