Quantum's Gen 5 Credit Model generates ECOA-compliant adverse action reason codes automatically — every decision includes reason codes, not just a score. We produce model governance documentation, audit trails, and version history suitable for regulatory examination. Fair lending analysis is part of our model governance process. The model is designed to be examiner-ready.

The lift depends on which modules you select. Each module has its own API surface and integration scope — a single module integration is significantly lighter than a full platform build. We provide a detailed integration runbook, API schema documentation, and dedicated developer support throughout. Sandbox access is provisioned within 48 hours of agreement, and we walk your engineering team through the full technical scope in a 60-minute discovery call.

QLS uses versioned APIs. Breaking changes are announced a minimum of 60 days in advance. Backward compatibility is maintained within versions. We publish a changelog and version deprecation timeline with every release, and partner engineering leads are notified directly of any upcoming changes affecting their integration scope.

Data inputs vary by module. For the Decisioning and Credit Model modules, you provide standardized application and business financial data per the QLS data schema. All data sharing is governed by a GLBA-compliant data sharing agreement reviewed by both legal teams before execution. QLS does not use or retain applicant data beyond what is required for the elected module's function. We provide a data flow diagram and security posture brief to your legal and risk teams in advance.

That is exactly what Flex is designed for. You use only the modules you need alongside your existing systems — without creating platform dependency. No exclusivity is required in any partnership agreement. Modules integrate alongside what you already have, and you can scope individual modules independently. If your requirements change, you add or adjust modules without commercial renegotiation.

A full internal build for equivalent capabilities requires underwriting infrastructure, compliance frameworks (ECOA, GLBA, adverse action, state disclosures), model governance, fraud and identity verification, and ongoing examiner readiness. Industry experience suggests 18–36 months and $3–5M+ in investment for production-grade infrastructure. Flex delivers production-tested modules — the same capabilities running on $7B+ in SMB originations — in 30–120 days at no upfront infrastructure cost.
