PunchOut Catalog Integration allows buyers to connect to supplier e-commerce systems to view pricing, availability, and other product information in real-time. It streamlines the purchasing process for buyers and increases sales for suppliers. PunchOut integration connects a company's e-commerce platform to supplier catalogs through web services, APIs, or file transfers. This allows buyers to search for and purchase supplier products without leaving their company's website, saving time and reducing errors. Integrating PunchOut catalogs automates ordering and provides consistent shopping experiences for buyers.
