What Is Dunning and How Does Payment Recovery Work?

Dunning is the process of recovering a failed recurring payment: retrying the collection, notifying the customer, and deciding what happens to the subscription while the payment is outstanding.

Most failed subscription payments are not customers choosing to leave — they are insufficient funds on the collection date, an expired card, or a temporary bank issue. Losing these customers is called involuntary churn, and a good dunning process recovers a large share of it.

Why do recurring payments fail?

• Insufficient funds — the account or card had no funds on the day. Usually temporary and the most recoverable failure.
• Expired, lost or reissued cards — the stored card details are no longer valid.
• Closed or blocked accounts — the bank account can no longer be debited.
• Disputes and stops — the customer has stopped or disputed the collection, which is a cancellation signal, not a retry candidate.

The reason code matters: retrying a closed account wastes attempts and fees, while retrying insufficient funds at the right time often succeeds. See card declines and response codes and debit order unpaids, returns and resubmissions.

What does smart retry timing look like in South Africa?

Retrying a failed payment the next day at the same time usually fails again for the same reason. Retries succeed when they land when money is in the account, and in South Africa that is driven by salary dates: most consumers are paid between the 25th and the 1st of the month.

A practical retry approach:

• Retry insufficient-funds failures on or just after the customer's likely salary date rather than on a fixed short interval.
• Space retries out rather than exhausting them in the first few days.
• Cap the number of attempts and stop retrying hard failures such as closed accounts immediately.

How does debit order tracking help?

Debit orders come with a recovery mechanism built into the rails. With DebiCheck, a collection can be submitted with tracking: the customer's bank monitors the account for a specified period — up to ten days — and completes the collection as soon as sufficient funds arrive. This turns a single collection attempt into a continuous one, without you scheduling retries yourself.

Tracking must be disclosed in the mandate, and it works particularly well combined with salary-date collection: a debit submitted just before payday with tracking catches the salary deposit as it lands. See DebiCheck collections, tracking and retries.

What should customer communication look like?

Retries recover funds; communication retains customers. A dunning sequence typically includes:

1. Immediate notice that the payment failed, with the reason in plain language.
2. A self-service way to fix it — pay now via a payment link, or update card or bank details.
3. Reminders before each retry, so the customer is not surprised by another attempt.
4. A final notice before suspension or cancellation.

Keep the tone factual and helpful. Most customers want to keep the service and simply need an easy way to pay.

What is a grace period?

A grace period keeps the subscription active for a defined time after a failed payment while recovery runs. Cutting access immediately converts a recoverable payment failure into a cancellation; a short grace period gives retries, tracking and reminders time to work. Define when access is suspended, when the subscription is cancelled, and whether recovered payments restore access automatically.

What does a complete recovery flow look like?

1. Payment fails and the reason code is classified.
2. Hard failures skip retries and go straight to customer contact.
3. Soft failures are retried on a salary-aware schedule, or tracked on the debit order rails.
4. The customer is notified with a self-service payment or update option.
5. The subscription moves through grace, suspension and cancellation states on a defined timeline.

Kwik's collection tools support tracked DebiCheck collections, resubmissions and payment links for once-off catch-up payments, which covers the recovery mechanics of this flow.
