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 and mail Sunko WSC a check. Depending on the financial institution, they may or may not charge a fee for the service. Payments may take up to seven business days for the check to reach our office.  Please allow enough processing/mailing time so that it arrives at the Sunko WSC office before the 15th of the month to avoid the late fee.  Please consult with your bank for more information.
