Differences most comparisons miss
Worth knowing about Coupa
- Thoma Bravo closed its roughly $8.0B take-private on 2023-02-28; Coupa is no longer listed on Nasdaq.
- Supplier risk (Risk Assess) came from the 2018 Hiperos acquisition, so it is an acquired module rather than native to the core procurement app.
- Costbench data shows auto-renewing contracts with a 1 to 3 year minimum and about 23% average negotiated discount, so list price is not the paid price.
- About 63% of G2 reviewers are enterprise (G2 comparison data).
Worth knowing about SAP Ariba
- G2 ease of use scores 7.9 versus 8.3 for Meets Requirements, so usability trails capability.
- Review counts on G2 comparison pages vary from about 706 to 747 by snapshot.
- Not designed for SMB procurement; no public price.
