Real-time anomaly detection for Stripe webhooks. Catch duplicate charges, payment failures, and silent lapses before your customers do.
You're probably already monitoring uptime and error rates. But nobody's watching your billing stream.
Failed dunning flows silently let subscriptions lapse — you find out at month-end when MRR is already down.
A promo code bug creates negative invoices. Stripe processes them without question. You never get notified.
Card fraud spikes your dispute rate overnight. You get notified after the damage — and the chargebacks — are done.
Event processing stalls, events pile up, your app is blind — and customers are confused about their subscription state.
Every event in your Stripe webhook stream runs through all 7 detectors in real time.
| What BillingWatch watches | What it means for you |
|---|---|
| Charge failure spike (>15%) | Dunning failure or payment method issue — catch it before churn |
| Duplicate charge | Same customer charged twice — know before they dispute |
| Fraud spike | Card testing or stolen cards — stop the bleeding immediately |
| Negative invoice | Broken promo stacking — your revenue numbers just got weird |
| Revenue drop (>15%) | Something's wrong upstream — find out in minutes, not days |
| Silent subscription lapse | Active sub, no payment — invisible churn accumulating |
| Webhook lag (>10 min) | Your event pipeline is backed up — your app is flying blind |
No code changes. No SDK to install. No dashboard to babysit.
Add the BillingWatch endpoint to your Stripe dashboard. One URL, one minute.
BillingWatch validates every event in real time — charge failures, fraud spikes, webhook lag, and more.
When something looks wrong, you hear about it via email, webhook, or Slack — before your customers do.
One caught duplicate charge dispute saves more than the monthly fee. Scale as your Stripe volume grows.
Radar catches fraud at authorization. Datadog catches infra. BillingWatch catches billing pattern anomalies — the stuff nobody else watches.
| Alternative | Why BillingWatch wins |
|---|---|
| DIY webhook monitoring | Takes weeks to build, needs maintenance. We're already built. |
| Stripe Radar | Fraud only — no operational anomalies or billing pattern detection. |
| Datadog / Grafana | Requires instrumentation, expensive, and overkill for billing monitoring. |
| Watching the Stripe dashboard | Reactive. We're proactive — we come to you. |
| Nothing | Most common approach. Also most expensive when something breaks. |
Just add a webhook endpoint in the Stripe dashboard. That's it — no code changes, no SDK to install.
Radar catches fraud at the authorization level. BillingWatch catches anomalies in your billing patterns — duplicate charges, dunning failures, webhook lag — stuff Radar doesn't see.
We only receive webhook event payloads — the same data Stripe already sends to any endpoint you configure. We never store card numbers or customer PII beyond what's in the event.
Pro and Scale plans support custom detector rules. Tell us what billing edge case keeps you up at night — we'll build it.
BillingWatch watches your Stripe stream 24/7 so you don't have to.
