This paper studies the retailer’s optimal ordering and pricing under the condition of the initial cap-ital constrained． In such a setting，we discuss the optimal ordering and pricing under the no financial service， external financial service in which a third party financial institution( e． g． ，bank) offers a commercial loan to the retailer，internal financial services in which the manufacturer offers trade credit contract to the retailer． We give out the optimal ordering polices under the retailer’s differential initial capital． In the end，a numerical a-nalysis is employed，our results shows that the ordering polices can be severely affected by the lack of capital and the retailer’s order quantities can be improved． The financial services can create value for the retailer who faces capital constrained． In additional，the trade credit policy given by the upper manufacture mostly is better off the third financial service． These results can be used for the reference of the retailer’s managers when they make decisions．
