Connecting Coupa and SAP Ariba with eConnect

Connect Coupa and SAP Ariba via the PSB: UBL-to-cXML transformation and onboarding.

Integration methodPSB (enterprise)DirectionSend + ReceiveMinimum subscriptionProfessionalContract requiredYes (via sales)

eConnect can deliver in 2026 invoices to recipients using Coupa or SAP Ariba (SAP Business Network). The platform automatically transforms your UBL invoices to the cXML format required by these platforms. Onboarding is handled by the eConnect tech team.

Coupa

With a Coupa integration, the following happens:

  1. eConnect transforms your UBL invoice to cXML for delivery to the Coupa recipient.
  2. The customer creates accounts on the Coupa CSP test and live environments.
  3. The receiving party creates a Shared Secret for authentication.
  4. The eConnect tech team completes the actual connection.
SAP Ariba (SAP Business Network)

SAP Ariba works similarly to Coupa, but through the SAP Business Network:

  • Above a certain annual volume or amount, SAP requires a paid subscription (minimum Silver/Enterprise for automated cXML exchange).
  • Unlike Peppol, Ariba works with 1-to-1 trade relationships: the supplier shares an AN-ID with the buyer.
  • The test environment uses an AN-ID with suffix "-T".
