Workday is not a procurement company that added HR; it is an HR and finance company whose customers gradually moved purchasing into the same suite. That origin shapes everything about a Workday punchout project. The buyers who ask for it are often services organizations, hospitals, universities and mid-market enterprises that run Workday Financial Management, and the person configuring your connection is a Workday administrator in the finance team, not a dedicated procurement-network operator.
How punchout works in Workday
Under the surface, Workday speaks the same language as the rest of the cXML world: punchout to an external catalog, cart returned as a PunchOutOrderMessage, purchase orders and invoices transmitted as cXML documents. The full round trip is the one described in our punchout guide. On the Workday side, your store is configured as a supplier link: the admin creates a punchout connection carrying your URL, your credentials and the identity pair the documents will use, and exposes your catalog to requesters inside their requisition screens. Requisitions built from your transferred cart flow through Workday's own approval chain, and the resulting purchase order can be transmitted back to your endpoint as a cXML OrderRequest.
There are no supplier network fees anywhere in this flow. Workday has no equivalent of the Ariba network account, no subscription tiers and no transaction percentage. In fee terms it sits with Coupa and Oracle on the friendly side of the ledger, far from the Ariba fee schedule.
An honest note about the evidence base
Compared with Ariba or Coupa, far less about Workday punchout is publicly documented: fewer supplier guides, fewer buyer checklists floating around, fewer war stories. We say that plainly because it changes how a good integration is run. Where public documentation is thin, per-connection verification does the work instead. On a first Workday connection we explicitly test, rather than assume: which transfer encoding their tenant sends and expects, how credentials are passed on the setup request, whether the purchase order is transmitted as cXML or handled by their team another way, and which item fields their requisition screens require, units of measure and commodity codes above all. Each answer becomes configuration, and the raw XML logs of the test session become the shared record both sides sign off on.
What PunchRelay does for a Workday connection
PunchRelay gives your Shopify store the endpoint the Workday admin points their supplier link at: credential validation, punchout sessions opened on the Shopify B2B company location you assign, contract pricing from your B2B catalogs and price lists, and quantity rules enforced in the cart before the PunchOutOrderMessage leaves. Incoming OrderRequest documents are acknowledged in under 150 ms and created as Shopify orders with the punchout lines and prices. If a particular tenant does not transmit purchase orders electronically, the transferred cart session is one click away from becoming a Shopify draft order, so the order still never gets retyped.
Everything in both directions is logged raw. With a finance-team admin on the other side rather than a procurement network's support desk, self-explanatory logs matter even more: they let a Workday administrator confirm what their tenant sent without opening a support case with Workday.
