Bringing Suppliers and Customers Closer The Punchout Service app helps increasing vendors revenue and significantly reducing the operational effort of the procurement team. With the Punchout Service app, Vendors can easily create a Punchout Catalog that can be directly accessed from the SAP systems of their customers. The end users access the Punchout to browse and shop the items they need. Every item requested from the Punchout Catalog automatically creates a Purchase Order without the need of going through the quotation process
