Commercial Rate-Card & Effective Unit-Cost Audit Methodology
How our pricing desk normalizes hourly, piece-rate, and hybrid SaaS quotes into comparable defect-adjusted cost per 1,000 accepted rows.
Defect-Adjusted Cost Per Accepted Row (`C_eff`)
We compute `C_eff = (Gross_Vendor_Bill + Internal_Engineering_QA_Cost) / Accepted_Compliant_Rows`, pricing Staff ML Engineer review and triage bandwidth at $185/hr.
Contributor Pay vs. Billed SOW Rate Spread
By cross-referencing enterprise SOW quotes against verified contributor payout receipts on the same platforms, we estimate each vendor's gross take-rate and flag >50% BPO spreads that trigger contributor churn.
Enforceable Lot Rejection, Calibration Caps & Rollover Rights
Vendors earn top commercial grades only when they accept objective programmatic acceptance tests (unit-test exit codes or Krippendorff's alpha thresholds) tied to 100% free lot replacement.
