When the supplier offers the trade credit to the retailer, their target profit will change and supply chain's profit will increase due to coordination.

The inventory model of trade credit in supply chain is developed, and the credit period and the order quantity for coordinating supply chain are educed, and the effect of the model for sharing the profit and supply chain's coordination is analyzed. Finally the results are analyzed by conducting numerical examples.
