Dunning

What is dunning?

Dunning is the process of communicating with customers to collect payment after a failed transaction. In the context of subscription businesses, dunning typically involves a sequence of automated emails, SMS messages, or in-app notifications that alert the customer their payment failed and prompt them to update their billing information.

The term originates from the verb "to dun," meaning to make persistent demands for payment. In modern SaaS and subscription commerce, dunning has evolved from aggressive collection letters into a nuanced, multi-channel communication strategy designed to retain customers, not just collect debts.

Why dunning matters for subscription revenue

Failed payments are often invisible to the customer. Their card was declined, but they received no notification from their bank. Without dunning, these customers silently churn — losing access to a service they intended to keep paying for. This is the core of involuntary churn.

Effective dunning recovers a meaningful percentage of failed payments by simply informing the customer and making it easy for them to act. The key variables in a dunning sequence include timing (when to send the first message and follow-ups), tone (helpful vs. urgent), channel (email, SMS, in-app), and the ease of the payment update flow.

Dunning vs. smart retries

Dunning and payment retries are complementary but distinct strategies. Retries attempt to charge the same payment method again without customer involvement. Dunning asks the customer to take action. The most effective payment recovery combines both: automated smart retries that resolve soft declines silently, paired with dunning sequences that engage the customer only when retries cannot recover the payment.

FlyCode combines AI-powered retries with intelligent dunning triggers, ensuring customers are only contacted when necessary and at the moment they are most likely to respond.
