Payments can be sent one of three ways, Electronically (ACH), Corporate Check (Bill Payer Co. check), or Draft Check (check drawn off customer's account). When payments are entered, you are required to enter the due date or a date prior to the due date. The payment is sent before that date, depending on the payment method so as to arrive on or before the due date. You are not debited until the due date if the payment is sent electronically or by corporate check. If the payment is sent via laser draft, you are debited when the check clears and an image will be returned in your statements with the rest of your imaged checks.
