The 5 Stripe Signals That Predict Churn Before It Happens

Your billing data knows more than your product analytics

Product analytics tell you what users did yesterday. Billing data tells you what they'll do next month. Every failed charge, every downgrade, every unusual payment gap creates a pattern — and patterns predict behavior.

After analyzing thousands of B2B subscription accounts, we've identified five Stripe signals that consistently predict churn 30-90 days before cancellation. None of them require product usage data. All of them are sitting in your Stripe dashboard right now.

1. Failed invoice ratio

The ratio of failed invoices to total invoices over a rolling 90-day window is one of the strongest single predictors of churn. Not just hard declines — soft declines matter too.

A customer whose card fails once might just have an expired card. A customer whose invoices fail 3 times in 90 days is 4.7x more likely to churn than one with zero failures. The signal isn't the failure itself — it's the pattern of repeated failures that indicates disengagement from maintaining the subscription.

2. Cancel intent duration

Stripe records when a subscription enters a cancellation-pending state — the customer has clicked cancel but the subscription hasn't expired yet. The duration between cancel-intent and either reinstatement or final cancellation is deeply predictive.

Customers who cancel and reinstate within 24 hours are exploring. Customers who sit in cancel-pending for 5+ days have already made their decision. If you're not measuring this window, you're missing your best intervention timing.

3. Payment volatility

Consistent MRR from a customer means stability. Fluctuating payments — an upgrade followed by a downgrade, then a pause, then a reactivation — signal indecision.

We measure payment volatility as the coefficient of variation of monthly payment amounts over 6 months. High volatility accounts churn at 2.3x the rate of stable accounts. They're not unhappy enough to leave immediately, but they're actively questioning the value.

4. Time-to-payment on invoices

How quickly does a customer pay their invoice after it's issued? Stripe tracks this automatically. Customers who pay within hours of invoicing are engaged. Customers whose payments consistently take 7+ days to clear are showing passive disengagement.

This signal is especially powerful for annual contracts approaching renewal. If time-to-payment has been trending upward over the last 3 invoices, renewal risk is high — regardless of what your CS team thinks.

5. Subscription age relative to cohort

Not all tenure is equal. A customer who's been with you for 18 months might seem stable — until you realize that 80% of their acquisition cohort churned in months 6-12. That 18-month customer has already survived the danger zone, making their raw tenure less informative than their relative position.

ChurnBurner normalizes tenure against cohort survival curves. A 6-month customer in a cohort with 90% 6-month retention is safer than a 12-month customer in a cohort with 40% 12-month retention.

What to do with these signals

Any one of these signals in isolation is interesting. Combined into an ensemble model, they produce a 0-100 risk score with 4.3x top-decile lift — meaning the top 10% of predicted-at-risk customers are 4.3x more likely to actually churn than a random 10%.

The key insight: you don't need product usage telemetry to predict churn. Your billing system already knows. The question is whether you're listening.

ChurnBurner connects to your Stripe account and scores every customer on these signals (plus 8 more) automatically. No integration beyond Stripe. No usage tracking SDK. Your first risk report is ready in under 5 minutes.
