Why is my customer asking for "PunchOut"?

If your customer, the buying organization, is asking for PunchOut, it's because they are implementing an e-Procurement system to order products online from suppliers like you. This system requires that they can automatically log in to your e-Commerce website from their e-Procurement system, view your website inside a browser frame in the e-Procurement system's user interface, add items from your website to the e-Procurement system's shopping cart (which may also include items from other websites), and pre-approve the order before fulfillment. PunchOut is the solution that enables this process to happen seamlessly. By implementing PunchOut, you can help your customer to streamline their purchasing process and make it easier for them to do business with you.
