Dunning is a sequence of three letters escalated from payment falling due to a pre-legal demand. Ideal for low value high volume accounts, the communications allow customers to communicate outstanding queries and payment promises. The interactive communication reduces inbound and outbound call volumes and escalates the account status if payment is not received. Intelligent recognition of current queries and payment promises prevents the letter sequence from escalating to the next communication if an account is queried or has been promised for payment.
