Dunning

Dunning is the process of contacting customers whose payments have failed and attempting to collect what's owed. The term dates back to 17th-century England, where a "dun" was a demand for payment of a debt. In modern SaaS, it refers to the automated systems that retry failed charges and send recovery emails to customers. Most founders don't think about dunning until they look at their churn numbers and realise a significant chunk is involuntary.

How SaaS dunning works

When a subscription payment fails, a dunning system kicks in. The first line of defence is smart retries: additional attempts on a separate schedule from your processor's native retries, timed for when payments are most likely to succeed.

• Recovery emails: a sequence notifying the customer and prompting them to update their payment method
• Pre-dunning alerts: proactive notifications when a card is about to expire, before any payment fails
• A grace period that keeps the subscription active while recovery is attempted, typically 14-28 days

Why it matters

Without dunning, every failed payment is a lost customer. Full stop. With a proper dunning system, SaaS businesses typically recover 40-75% of those failures. At $29/month, a dedicated tool like ChurnWard often delivers a 10x+ return by recovering revenue that would otherwise disappear silently.
