Billing anomaly detector

Watches Stripe / billing for charge failures, churn risk signals, and revenue leakage. Daily ledger.

What it does

Hourly scan of Stripe + your billing system for: failed charges (with retry status), declined cards (notify customer), unexpected refunds, voluntary cancellation patterns, dunning-recovery opportunities. Flags revenue leakage (e.g., free-trial users not converting at expected rate, churned customers no one called).

Inputs

Stripe API key. Monthly revenue baseline. Cancel/churn definitions.

Outputs

Daily billing-health Slack post. Per-customer recovery suggestions. Monthly revenue-leakage report.

Cost per run

~$0.05 per active customer monitored per month.

Models used

Claude Haiku for transaction classification. Custom scoring for churn-risk indicators.

Best for

B2B SaaS with subscription billing. Multi-brand operators with billing across multiple Stripe accounts.

Not for

One-time-purchase B2C brands (different problem shape). Pre-revenue brands.

Common questions

Does it auto-retry failed charges or auto-message customers?

By default, no — Stripe handles retries via dunning settings, and we suggest customer outreach for human review. You can opt into automated dunning emails after 30 days of supervised use.
