Fintech: Merchant Underwriting Review with Claude Code: Build vs Buy Decision
A production playbook for merchant underwriting review in fintech operations using Claude Code: build vs buy decision, run-scoped inputs, logs, typed results, and artifacts.
Audience: Fintech risk teams underwriting merchants
The problem
Fintech risk teams underwriting merchants need merchant underwriting review to run repeatedly against applications, bank statements, websites, KYC docs, and risk policies. In fintech operations, the pain is not one good answer; it is repeatability, auditability, exception handling, and evidence that survives handoff.
Implementation path
Compare the work required to operate merchant underwriting review: sandbox lifecycle, provider credentials, input injection, logs, artifact delivery, retries, and result validation.
Tradeoffs and failure modes
Building gives total control; buying the runtime compresses the path to a customer-facing workflow. For merchant underwriting review, the practical test is whether a second run can be debugged, retried, and consumed by a product without reading the raw agent transcript.
Decision table
Build internally if you need bespoke infrastructure primitives.
Use Argo if you need merchant underwriting review as a product workflow: inputs, Claude Code, logs, result JSON, and artifacts.
Use both if a specialized sandbox must sit behind a stable run contract.
