PunchOut, also known as cXML Punchout, Procurement Punchout, and OCI Roundtrip, is a widely used protocol in the e-Procurement industry. It allows for secure online shopping and ordering between e-Commerce platforms (such as Magento, Woo, Shopify, Episerver, Prestashop, Big Commerce, OpenCart, Oro Commerce, etc.) and e-Procurement systems (such as Coupa, SAP Ariba, Workday, Oracle, Jaggaer, iValua, Birchstreet, SAP SRM, etc.). This protocol has been around for over two decades and is now supported by all e-Procurement and ERP systems. By using PunchOut, your customers can easily and securely purchase products from your e-Commerce website using their preferred e-Procurement system.
