How To Add Additional Debt To A Payment Arrangement
To transfer additional debt to an existing payment arrangement:
• Open Payment Arrangement for Bills in update mode.
• Select the existing payment arrangement in the search.
• Select the debt to be transferred to the payment arrangement (by turning on/off the checkboxes adjacent to the Unpaid Bills amounts).
• Enter the number of Installments or the Arrange Amount.
• Click the Change button.
Note: 
After transfer. After transferring the funds to the payment arrangement service agreement, confirm the account's payoff and current balances make sense (the payoff balance is the total amount of debt that the account will eventually have to payoff, the current balance is how much they currently owe. The account's payoff and current balances are displayed in the page's second section. If you do not understand the difference between payoff balance and current balance, refer to Current Amount versus Payoff Amount.
