The B2B Punchout & EDI Integration Guide
Your largest buyers often cannot order from a normal storefront. They buy through a procurement platform, and if your store does not speak punchout and EDI, you are not on their approved list.
This guide explains how punchout and EDI work, and what it takes to make your store sell into procurement the way enterprise buyers already buy.
