If your account does not have sufficient funds at the time your Bill Pay payments are posted, your payments will be designated as non-sufficient funds (NSF). Your account will be charged for each NSF item. The fee charged will be assessed on your account at the time your monthly service fee is debited.
To avoid NSF fees, you can setup overdraft proection on your accounts.  For more information or to sign up for overdraft protection select the related link below.
