Payment failures compound silently
A rising failure rate doesn't trigger dashboards. There's no alarm. You find out at end-of-day reconciliation — after the damage is done.
Failure rate crept up undetected
Your card decline rate climbed from 2% to 11% over two hours. No alert fired because your monitoring only watched for complete outages. Revenue was bleeding the entire time.
Refund spike from a broken discount
A discount code bug issued a refund on every transaction for 90 minutes. It showed up as "normal activity" in the Stripe dashboard until end-of-day reconciliation.
Card expiry wave hit your subscribers
15% of your subscription cards expired on the same billing cycle. Silent failed charges compounded for 48 hours before anyone noticed the churn spike.
Catch every failure signal before it becomes a crisis
NotiLens watches your payment event stream for rising failure rates, refund spikes, and subscription declines — and alerts you the moment a pattern emerges.
Failure rate baseline monitoring
NotiLens detects payment failure rate spikes via your signal rules and auto-learned anomaly detection — flags unusual patterns even if you haven't set a manual threshold.
Refund anomaly detection
Track refund volume over time. When refunds spike beyond your normal range — due to a bug, fraud wave, or policy issue — NotiLens fires an alert with the deviation and count.
Subscription decline tracking
Monitor recurring charge failures separately from one-off payments. Get alerted when your subscription failure rate climbs, giving you time to run card update campaigns before churn hits.
Manual rules + auto anomaly detection
You get two layers of detection — not one. Set your own thresholds for what you know matters. NotiLens learns the rest automatically.
amount > $100. Fires only when your rule is met.What NotiLens sends when payment failures spike
Every alert fires within 60 seconds of detection — with the specific metric, deviation, and time window so you can act immediately.
A 10% failure rate doesn't look alarming in a weekly report.
Over a 4-hour window, it can represent thousands in lost revenue — and dozens of frustrated customers who won't come back.
One caught failure rate spike pays for the year
A 4-hour failure rate spike during peak hours costs far more than a year of NotiLens. Here's what teams typically recover.
