Why dunning matters
A large share of subscription churn is involuntary: cards expire, limits trip, banks decline, while the customer still wants the service. Dunning recovers exactly those, which makes it the cheapest retention program a recurring-revenue store runs.
What a dunning flow includes
- Smart retries timed to when declines tend to clear
- Customer notices with a one-tap update-card link
- Account updater and network tokens catching reissued cards silently
- A grace period before access or shipments stop
Questions
How many retries are reasonable?
A handful over one or two weeks, intelligently spaced: banks read rapid-fire identical retries as risk. Modern billing systems time attempts to decline codes rather than a fixed daily hammer.
What tone should dunning emails take?
Helpful, not accusatory: the customer usually did nothing wrong. “Your card didn’t go through, one tap to fix it” recovers; “payment failure notice” language churns people who would have stayed.
