When joining Budget Billing, the monthly payment is determined by totaling the previous year’s usage, dividing that total by 12 and multiplying by the current rate. The resulting average amount will be billed on the following month after signing up and continue for the next 11 months. Payments must be made monthly to remain on the Budget Billing program—no skipping months and doubling up later. On the 12th month, the Budget Billing monthly payment will be recalculated based on the actual services and commodities used during the Budget Billing year. Customers have the option to “True Up” or “Roll Balance” on the 12th month. Those who choose to True Up will see the balance, even if it is a credit, applied to the first bill of the new budget billing year and due accordingly. Customers who choose to Roll Balance, including those with credit balances, will see that remaining balance calculated into the new budget for the coming year.
