Most source-to-pay suites focus on getting suppliers onboarded, sourcing events won, purchase orders raised, and invoices matched. That is genuinely valuable, and GEP SMART does it well at enterprise scale.
But running the procurement workflow is not the same as capturing what the contract promised. Once the sourcing event closes and the deal is signed, a different set of questions starts. Is the supplier hitting the volume tier that unlocks the rebate? Has the price protection kicked in? Are incentive claims being filed before the window closes? Do finance's accruals match what has actually been earned? GEP SMART cannot answer those questions in real time. It runs the workflow. It does not reconcile the money.
Vendortell measures what the contract delivers.
Vendortell picks up exactly where GEP SMART stops. It connects signed contract terms to live ERP data (SAP, Microsoft Dynamics, Oracle, Visma) and tracks whether each supplier is delivering against what was agreed. Rebate thresholds, volume commitments, incentive tiers, claim deadlines: all monitored continuously, not audited nine months later at year-end.
The result is a finance-grade view of your contract portfolio that no source-to-pay suite is built to produce: what you negotiated, what was delivered, and what you have earned. Live in 30 days. This is what Contract Performance Management delivers.
How they compare
Who should you choose?
Choose GEP SMART Choose GEP SMART if your primary pain is upstream procurement: sourcing events, supplier onboarding, PO automation, and spend classification across a global multi-ERP enterprise. GEP SMART is a Leader in the 2026 Gartner Magic Quadrant for Source-to-Pay Suites and a strong fit for that problem.
Choose Vendortell Choose Vendortell if the money is leaking post-signature. If your team cannot reliably say what each supplier contract is actually delivering, whether rebate thresholds are being crossed, or whether the accruals on your balance sheet reflect what has really been earned. Vendortell closes the gap that GEP SMART was not designed to. Most customers recover more in uncaptured rebates within the first two quarters than the platform costs for the year.
Use both Run both if you have both problems. Vendortell reads contract data from GEP SMART or any other source-to-pay suite and adds the post-signature financial reconciliation layer on top. They are complementary by design. Vendortell sits alongside contract lifecycle management and connects to vendor rebate management for procurement teams. Book a 45-minute demo to see it live.
