A PunchOut catalog lets a buyer shop your website from inside SAP Ariba, Coupa, Jaggaer or GEP. They "punch out" to your catalog, see their own contract prices and products, fill a cart, and the cart goes back into their procurement system for approval. The approved purchase order then comes to you automatically.
Large buyers often ask for PunchOut before they will add a supplier. Getting it right means cXML or OCI messages that each buyer's system accepts, per-buyer catalogs and pricing, and a round of testing with every buyer. We handle all of it, and we test every connection with our own PunchOut Tester before your buyer does.
