Joining your customer’s e-Procurement vendor’s supplier network is a common request for suppliers with PunchOut capability. This is because some e-procurement vendors (like Ariba and Coupa) require all PunchOut requests to be routed through their supplier network. Joining the supplier network is a simple process that usually takes only a few minutes. It has minimal impact on your PunchOut implementation. By joining the supplier network, you can ensure that your PunchOut requests are processed quickly and efficiently. This will improve your overall customer experience.
