Open Beta — Free while in beta

Your Stripe is silently losing money.
BillingWatch stops it.

BillingWatch watches your Stripe account 24/7 and alerts you the moment something goes wrong — charge failures, silent subscription lapses, revenue drops, or card testing attacks.

Catches the billing bugs your dashboard hides.

🚨 Charge Failure Spike Detected just now

34% failure rate in the last hour — baseline is 2.1%. Affecting 47 payment attempts. Revenue at risk: $3,240.

CRITICAL Revenue Impact Alert Sent

The billing problems you don't know about

Most billing issues are invisible until they're expensive. By the time you check your Stripe dashboard, the damage is done.

📉

Silent failure spikes

Charge failure rates spike during outages — nobody notices until MRR drops and customers are already angry.

👻

Subscription lapses

Active accounts that stopped paying accumulate silently. Zero errors. Zero revenue. Gone for weeks before you notice.

🚨

Card testing attacks

Fraudsters run hundreds of small charges through your account before your fraud detection kicks in. The bill hits later.

Promo code bugs

Stacked promo codes create negative invoices that go unfixed for months because no one is watching for them.

BillingWatch catches all of it — in real time, before it compounds.

BillingWatch watches your Stripe so you don't have to

7 real-time detectors. One Slack or email alert. Zero babysitting.

💥

Charge failure spikes

Fires when >15% failure rate in the last hour — way above your baseline.

👻

Silent subscription lapses

Active subscription, no payment in 30+ days. Revenue ghost accounts.

📉

Revenue drops

Fires when daily revenue is >15% below your 7-day rolling average.

🔁

Duplicate charges

Same customer + same amount within 5 minutes — stops double-billing fast.

Negative invoices

Promo code stacking creating <$0 bills. Catches revenue-draining bugs.

🐢

Webhook lag

Events queued >10 minutes unprocessed — your pipeline is backed up.

🚨

Fraud spikes

Charge volume 3x above your baseline — card testing attack signal.

Common questions

How long does setup take?
Under 5 minutes. Add one webhook URL to your Stripe dashboard. No code required on your end.
Does BillingWatch store my payment data?
No. BillingWatch only processes Stripe webhook event metadata — event types, timestamps, amounts. No card numbers or PII are stored. Ever.
What Stripe plan do I need?
Any Stripe account. BillingWatch uses webhooks, which are available on all Stripe plans including free.
Can I customize the detection thresholds?
Yes, on the Pro plan. Adjust failure rate thresholds, revenue drop percentages, and time windows to match your actual business patterns.
What happens if BillingWatch goes down?
Stripe retries webhook events for 3 days. BillingWatch will process queued events when it comes back online — events are never lost.
Can I get Slack alerts on the free plan?
Email only on the free plan. Slack, webhooks, and PagerDuty are Pro and Team features. Upgrade anytime — no contracts, cancel anytime.
