Sourcing agents can be paid through a commission-based or fee-based model. In a commission-based model, they earn a percentage of the total order value, typically between 3% to 10%. In a fee-based model, they charge a flat fee for their services, regardless of the size of the order. Some sourcing agents may use a combination of both models depending on the needs of their clients and the products being sourced. Ultimately, the payment structure is determined by the agreement between the sourcing agent and the client.
