Smart Retries

Smart Retries is a Stripe Billing feature that automatically reattempts failed subscription payments, using machine learning to choose retry timing instead of a fixed schedule. It's the automated engine inside a dunning process — when a recurring charge fails, Smart Retries decides when to try again.

How it works

A rules-based retry system charges again after fixed intervals (say, day 1, day 3, day 7). Smart Retries instead reads signals about the failed payment — the decline reason, the card type, the local time zone, historical patterns — and predicts the moment a retry is most likely to clear. A technical decline might be retried almost immediately; an insufficient-funds decline might wait until the customer's likely payday.

You still control the guardrails: you set the maximum retry window (for example, 1 week, 2 weeks, 1 month, or 2 months) and Stripe schedules attempts within it. Stripe reports that Smart Retries recover a meaningful share of payments that initially fail.

Why it matters

Most subscription payment failures are a declined payment from an expired card or a temporary funds shortfall, not a customer choosing to leave. Recovering these charges is the single biggest lever against involuntary churn, and every recovered payment protects MRR you already earned. Smart Retries pairs with a grace period, so the subscription stays active while retries run.

Smart Retries and ChargeBell

ChargeBell doesn't run retries — Stripe does — but it tells you when they matter. You get a Slack alert when a payment fails and a separate one when a payment is recovered after a recent failure, so you can watch your recovery flow work without opening the Stripe dashboard.
