Auto Pay with Bank or Credit Card Draft

For our customers who prefer not to mail or bring in their payments, we offer a personal bank draft program.  Complete the form and send in a voided check from the account you want to draft from and sign the permission slip.  Then, each month, your bill will be deducted from your checking account on the day that it is due.  You still receive a monthly statement to show you how much the bill is and it will show the date it will draft from your bank account.  For Credit Card drafts complete the form and either email your card information or a CSR can give you a call to obtain your card information over a secured phone line.
