Knowledge Base

Every supplier registration and change request is scored from 0–100 by the Tennessee Supplier Risk Engine. The score is built from 18 weighted factors grouped into five families: Identity, Banking, Velocity, Geographic, and Network.

How the score is computed

1. Each factor returns a signed weight (-10 to +50). Negative weights are "trust signals" (e.g. verified TN address, TIN matches IRS).
2. Weights are summed, clipped to [0, 100], then normalized.
3. The final score maps to a tier: - 0–34 → Green (auto-approve eligible if no hard blocks) - 35–64 → Yellow (manual review required) - 65–100 → Red (manual review + dual approver + investigation triage)

Hard blocks vs. soft flags

A hard block (e.g. invalid routing number, OFAC sanctions hit) forces the case to Red regardless of score and pauses any pending payment. Soft flags (e.g. recent banking change <30d, near-duplicate supplier) raise the score but do not auto-block.

Where to see the contributing factors

Open any case in the Supplier Risk Console. The "Risk Score" panel lists every factor that fired, its weight, and a link to the underlying evidence (TIN match payload, OFAC screen result, etc.).

How often it recalculates

The score recalculates on every save, on every re-run verification, and nightly for active suppliers (re-verification cadence).
