The 12 tools in detail
Ramp
Corporate card and spend platform with a free tier and a paid Plus plan, where purchase orders come from a Procurement add-on.
- Starting price
- $0 (Free); Plus $15 per user per month plus platform fee
- Pricing model
- per user plus platform fee
- G2 rating
- 4.8 (2,492 reviews)
- PO creation and approval
- Procurement add-on: PO management, custom intake.

Choose it if
- Companies that want cards, expenses and AP in one tool and are fine adopting its card.
- Teams that want a free entry tier with QuickBooks Online or Xero.
Skip it if
- Teams that need PO management without the Plus plan (Procurement is Plus or Enterprise only)
- Buyers who want a standalone procurement tool unconnected to a card program.
Worth knowing
- PO functions are a paid add-on and need Plus, so the $0 tier has no purchase orders.
- Plus fee has a platform component based on team size that the page does not quantify.
- ERP depth rises by tier: NetSuite and Sage Intacct only from Plus, Workday and Oracle from Enterprise.

Accounts payable automation platform with PO creation, 2 and 3-way matching and budget controls on top of ERPs like NetSuite and Sage Intacct.
- Starting price

- Mid-size companies with Dynamics, NetSuite, Sage or SAP.
Skip it if
- Buyers who need public pricing or a free tier.
- Teams wanting a standalone procurement suite (Procurement is an add-on to AP)
Worth knowing
- PO and procurement features are part of an AP-first product, sold as an add-on.
- Full-automation matching depends on Billy, its AI assistant; the base tier is semi-automated.
- Founding year conflicts across sources (2014 vs 2015)
Kissflow Procurement
Low-code workflow platform from Kissflow with a procure-to-pay product for requisitions, approvals and POs.
- Starting price

Choose it if
- Mid-size companies that want procurement workflows inside a general workflow platform.
- Teams that need custom approval flows beyond a fixed P2P template.
Skip it if
- Buyers who want published pricing.

Worth knowing

- Pricing model
- custom
- G2 rating
- 4.2 (559 reviews)
- Price / entry cost
- Custom quote only.
- Trial / free tier
- No free trial listed by the vendor.
Choose it if
- Large enterprises that need one suite for procure-to-pay, sourcing and supplier risk.

Skip it if
- Small teams: third-party data points to a median contract near $93k per year with 1 to 3 year commitments.
- Buyers who want public pricing or a fast self-serve start.
Worth knowing
- 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.
Tipalti
Accounts payable and mass payments platform with procurement (Approve.com), PO matching and expense modules.
