    Additional Features
    Recurring Billing includes these additional features.
System Retry Logic
    National Australia Bank
 automatically retries failed recurring payments based on the
            type of decline received from the service. The service retries the internal and external
            payment declines.If the Recurring Billing service encounters an internal processing error without sending
            the request out to the banking network, the service retries the payment until the error
            is resolved. 
If the recurring billing service encounters an external processing error when the request
            is sent out to the banking network, 
National Australia Bank
 retries the payment
            before changing the subscription status to suspended. If the issuer provides a reason code like "Do Not Retry", 
National Australia Bank
            stops all retry attempts. National Australia Bank
 immediately updates the
            subscription status to suspended.The maximum number of retries is five times and is based on the billing frequency. During
            the retry period, 
National Australia Bank
 changes the subscription status to
            delinquent.This example shows the system retry logic based on the billing frequency: 
- Daily: retry 1 hour later, 1 time
 - Monthly: retry every 2 days, 5 times
 - Weekly: retry every 1 day, 3 times
 - Yearly: retry every 15 days, 3 times
 
For a recurring payment that has a custom billing frequency, the Recurring Billing
            service retries a failed payment based on the billing frequency. As an example, suppose
            a payment fails for a recurring billing on a 14-day cycle. The recurring billing service
            uses the Daily retry logic and every 2 weeks uses the Weekly retry logic, even if the
            duration is the same.
Customer Notifications
    The Recurring Billing service sends email notifications to customers using the email
            address stored on the customer token. The system sends notifications for three defined
            payment events: 
- Prepayment notification: notification of an upcoming recurring payment.
 - Successful payment notification: notification of a successful recurring payment.
 - Failed payment notification: notification of recurring payment failure.

Decision Manager Integration
    Decision Manager
 IntegrationA recurring payment is a credentials-on-file (COF) transaction in a series of payments
            that you bill to a customer at a fixed amount at regular intervals that do not exceed
            one year. 
National Australia Bank
 saves and stores payment
            credentials for recurring transactions, ensuring compliance with COF best practices.Recurring transactions are considered low risk compared to unscheduled payments.
            Therefore, when the 
Decision Manager
 fraud detection system is enabled on your
            account, National Australia Bank
 does not submit recurring billing transactions to
                Decision Manager
 for fraud screening.For more information about the
