Billing: Usage-Based Billing Audit with Claude Code: SKILL.md Template
A production playbook for usage-based billing audit in billing operations using Claude Code: skill.md template, run-scoped inputs, logs, typed results, and artifacts.
Audience: SaaS billing and finance teams
The problem
SaaS billing and finance teams need usage-based billing audit to run repeatedly against usage events, invoices, contracts, credits, and customer disputes. In billing operations, the pain is not one good answer; it is repeatability, auditability, exception handling, and evidence that survives handoff.
Implementation path
Put the operating procedure in SKILL.md, keep examples beside the skill, attach usage events, invoices, contracts, credits, and customer disputes per run, and let Argo turn the folder into a repeatable Claude Code execution.
Tradeoffs and failure modes
A skill folder is less flexible than an open chat, but it gives the product a versioned workflow that can be tested and rolled back. For usage-based billing audit, the practical test is whether a second run can be debugged, retried, and consumed by a product without reading the raw agent transcript.
SKILL.md starter
# SKILL.md
You run usage-based billing audit using Claude Code.
Read only /skill/.argo/inputs.
Write artifacts to /skill/output/artifacts.
Return argo.result.v1 with body.type = "billing_usage_audit".
Run this on Argo
