Chargebee's Dunning applies for :

• Online payments
• Offline payments
• Direct debit payments
• One-time payments

In Chargebee, you can configure dunning email notifications. These emails will be sent to your customers informing them about the payment failure and reminding them to make the payment or update the payment method.

Smart retry is an intelligent, built-in dunning logic that initiates payment retries based on the type of gateway transaction errors. Chargebee classifies gateway transaction error codes into hard and soft declines.

• Hard declines are errors that need your customers' or your intervention
• Soft declines are the ones that result from a temporary issue, like say connectivity issue, and can be retried for a successful recovery at a later time

Hard declines will not be retried until an update in payment method happens and for soft declines, based on the error category and the chances of recovery, Chargebee will suitably decide an opportune time to retry. This not only helps recover your revenue promptly but it does it in the best and safest possible way.

Dunning for Online Payments is when Auto Collection is turned ON for a subscription and the initial attempt to collect the payment fails, Chargebee will retry payment collection and send emails to your customer informing them about the failed payment.

To setup dunning for direct debit payments, navigate to Settings > Configure Chargebee > Dunning for Online/Offline payments > Dunning for Direct Debit Payments and here you will find the following options to configure dunning for direct debit payments in your Chargebee site:

Chargebee active le dunning pour chaque client avec mandat de prélèvement automatique. Si règlement par virement → Auto collect OFF et donc pas de dunning. Si un client change de moyen de paiement, il se peut que ça ne s'active pas automatiquement.

If the invoice is still unpaid when the Dunning Period ends, you can define the final action taken on the subscription. You can choose to let the subscription remain active or cancel the subscription at once.
