Purchase order financing is a method for a business to obtain quick capital to fill single or multiple customer orders. There will be times when there are not enough funds available to cover the costs of doing business. As a result, there may be an order from a client that isn’t able to be fulfilled due to a lack of funds. A company may not be able to afford the supplies necessary to meet the client’s particular needs. Having to turn the order down would mean loss of revenue and harm a company’s reputation.
