SAP Business Network where sellers exchange punchout catalogs, purchase orders, and e-invoices with enterprise buyers.
SAP Ariba is enterprise procurement software, and the SAP Business Network built around it is where a large share of Fortune-scale purchasing actually happens. Buyers run sourcing, purchase orders, and invoice approval through it; sellers who want those buyers' revenue connect to it to publish catalogs, receive POs, and submit invoices electronically. For a vendor's revenue stack it sits on the order-intake edge: if your customer buys through Ariba, your quote-to-cash process has to speak its formats — PO flip, cXML punchout, network invoicing — or invoices stall in someone else's workflow.
Which of the capability map's modules SAP Ariba covers — each links to the module's own page, with every tool that supports it.

| Buyer Procurement Integration | Digital Commerce | Core | The network is the product — catalogs, POs, order confirmations, and e-invoices exchanged between buyer and seller |
The moat is the buyer network, not the feature set: when a large customer mandates Ariba, connecting is a condition of getting paid, not a choice. Deep integration with SAP ERP on the buyer side makes it the default procurement rail across much of the enterprise landscape.
Because enterprise buyers increasingly require suppliers to transact through their procurement network. Registering, handling POs, and submitting invoices through Ariba correctly can be the difference between net-30 and a payment stuck in an approval queue you cannot see.
Supplier-side fees depend on transaction volume and account type — SAP distinguishes standard from enterprise supplier accounts, and higher-volume relationships can carry network fees. Check the current supplier fee schedule for your volume before committing to a connection approach.
