What is PunchOut and how does it work?

“PunchOut” is an interface that enables customers to transfer product information from the suppliers’ online shop directly to their own procurement software.  As such, the customer can switch from their procurement software to our online shop at the touch of a button. As a result, you can place the products you want in your shopping basket and transfer relevant product data to the procurement system to then generate an order.


OCI and cXML: The most common PunchOut protocols

There are different PunchOut protocols that enable seamless integration between buyers’ purchasing systems and their suppliers’ catalogues. Choosing the appropriate protocol often depends on the specific requirements of the company and the systems used. The most common PunchOut protocols used in the e-commerce industry are cXML and OCI.

cXML (Commerce eXtensible Markup Language) is a general XML-based standard protocol developed by the American software company Ariba. In addition to exchanging product data, it also enables data exchange so that business documents can be communicated between procurement applications, e-commerce hubs and suppliers.

OCI (Open Catalogue Interface) is a standard interface developed by SAP for exchanging catalogue data records. OCI acts as a catalogue interface between ERP systems and external catalogues. OCI takes into account specific requirements of SAP applications and offers functions that can be seamlessly integrated into the processes of SAP systems.

Benefits of cXML- and OCI-PunchOut for businesses

PunchOut catalogues simplify and shorten the purchasing process. No orders from the shop are sent to the supplier during this process. You handle all your processes as usual in your procurement system but still enjoy all the advantages and functions of the online shop. This allows you to access a catalogue that has been specially adapted to your contractual agreements. You will receive all information about items such as availability or current discounts, which will always be updated in real time.
