cXML
Commerce XML - the procurement-focused XML standard developed by Ariba and now widely used across Coupa, Jaggaer, Unimarket, and other procurement platforms.
In practice
cXML supports purchase orders, invoices, catalogues, and punchout setup requests. It is the dominant format inside modern procurement workflows.
Why it matters
If your buyers run a procurement platform, cXML is usually the protocol of record.
