Billing Reconciliation Review

Use this skill to convert a high-stakes product decision into a concrete, measurable, reviewable operating artifact.

Workflow

1. Identify money systems, authoritative ledger, payment providers, entitlement source, payout surface, tax/invoice requirements, and support consumers.
2. Read references/billing-reconciliation-patterns.md.
3. Map event lifecycle from order/renewal through payment, entitlement, invoice, refund, dispute, payout, and adjustment.
4. Define reconciliation keys, expected invariants, mismatch classes, retry/repair workflow, and audit evidence.
5. Produce reconciliation matrix, state machine, exception queue, event schema, and support/admin view requirements.

When not to use

• Do not use when the job belongs to payment-platform-readiness — Provider integration, webhooks, ledger truth. Reconciliation patterns belong as reference depth inside payment readiness.
• Do not use for generic advice the base model already handles without this skill's specific artifact contract.
