Dunning
Dunning is the automated process of recovering failed subscription payments — retrying declined charges on a schedule and sending reminder emails or SMS with card-update links — to prevent involuntary churn.
Every subscription business loses customers it never meant to lose — to expired cards and bank declines, not dissatisfaction. Dunning is the system that wins them back automatically, and it’s one of the highest-ROI tools in subscription commerce.
How dunning works
When a renewal payment is declined, a dunning system steps in instead of immediately cancelling the subscription. A good dunning flow combines automated retries with proactive customer communication:
- Smart retries — re-attempt the charge on a schedule tuned to the decline reason (insufficient funds retries differently than an expired card).
- Dunning emails / SMS — notify the customer their payment failed, with a one-click link to update their card.
- Card account updater / network tokens — automatically refresh expired or reissued card details where supported.
- Pre-dunning — warn customers about cards expiring before the renewal even fails.
Why dunning is the highest-ROI retention lever
Failed payments cause a large share of all subscription cancellations — often 20–40%. These customers still want your product; they simply had a card problem. Recovering them costs nothing in new acquisition spend, so every recovered payment is almost pure margin. On a $50,000/month store, recovering even 10% of failed payments is $5,000/month that would otherwise have churned.
Dunning on Shopify
Shopify’s native subscriptions offer limited failed-payment recovery, which is why dedicated subscription apps build it in. RecurX includes decline-aware retry windows, dunning email/SMS sequences, and one-click card-update links on every plan — turning involuntary churn back into recurring revenue automatically.
Frequently asked questions
What does dunning mean?
Dunning is the process of communicating with customers to collect a failed or overdue payment. In subscriptions, it specifically means the automated retries plus reminder emails/SMS used to recover declined renewal charges before a subscription is cancelled.
How does dunning reduce churn?
It targets involuntary churn — cancellations caused by failed payments rather than dissatisfaction. By retrying declined charges and prompting customers to update their card, dunning recovers subscribers who would otherwise lapse, often 40–60% of failed payments on the first retries.
What is the difference between dunning and a refund?
They are opposites. Dunning recovers money a customer owes for a failed charge; a refund returns money to a customer. Dunning protects recurring revenue, while refunds reverse a completed payment.
