The Revenue Leak Map for SaaS — see where subscription dollars leak, who is affected, and what to fix.
Sellable, acquisition-ready micro-SaaS asset. Built for portfolio depth and clean handoff.
- Revenue Leak Flow — a dollar-proportional Sankey of MRR: retained revenue flows through, six leak types peel off. Ribbon thickness never lies.
- Leak Index (0–100) — a single banded score with a published spec and golden-case tests.
- Honest detection — every dollar traces to a real Stripe object (invoices in retry, past-due invoices, expiring cards, dead trials, live discounts, payment-failure churn). Forward-looking numbers are labeled projected. Disjointness rules prevent double counting.
- Per-customer drill-down — each leak node lists the actual affected accounts and amounts.
- Trend — every sync stores a snapshot; the dashboard charts Leak Index over time.
- Recovery sequences — daily cron emails affected customers (3 sequenced categories), deduped per customer per week, fully audited, dry-run without an email key.
- Branded CFO report — print/PDF export with methodology and basis labels (Pro).
