Most billing tools only read your Stripe. But the expensive leaks hide between Stripe and your own database — access granted with no charge, subscriptions cancelled in your app but still billing-active, authorizations never captured. I reconcile both sides and hand you the list.
| Stripe says | Your app says | Result |
|---|---|---|
| sub_1f2a·9c · active · $49/mo | user #8842 · cancelled | ⚠ leaking still has access, stopped paying |
| sub_1a7b·03 · active · $29/mo | user #3310 · active | ✓ matched |
| — no subscription — | user #5521 · Pro granted | ⚠ leaking access granted, never charged |
| pi_3k9d·11 · uncaptured · $120 | authorization expired | ⚠ leaking authorized, never captured |
Failed cards, expired cards, zombie subscriptions, refunds where access was never pulled, webhooks that dropped and left your app out of sync with Stripe. None of it shows up on your MRR chart. All of it is recoverable — once you can see it.
I use a Stripe restricted API key. It physically can't charge, refund, or change anything — Stripe blocks every write at the API level.
The audit only reads non-sensitive fields (last-4, expiry, brand). Full card numbers never leave Stripe, never reach me.
Delete the key the moment the report lands. I keep nothing you don't want me to keep.
Prefer not to share a key at all? Run my small read-only script on your own machine (~400 lines of plain Python — you can read every line) and just send me the output. Your key and your data never leave your machine. Ask for the script →
I've spent years building card, ledger, and cross-system reconciliation for a fintech — the unglamorous plumbing that has to be exactly right because it's real money. Reconciling two systems that should agree is literally what I do. This audit points that at your Stripe.
