Payment Through Financial Institution Online Bill Pay

Many financial institutions such as major banks offer their customers the ability to pay their bills via an online bill payment service (through your bank's website). Normally, these services debit the customer's checking or savings account to pay the bill. Depending on the financial institution, they may or may not charge a fee for the service. Payments may take up to seven business days to post to the customer's account. Please consult with your bank for more information.


Payment Policies


The late charge will be added to the account balance if not paid in full by the 15th of each month.

If your payment is past due, paying online will not relinquish responsibility for any penalties or late fees.

Payments not paid in full by the 25th of each month will be locked until the bill is paid in full. A lock fee of $50 will be automatically added to the bill balance.
