The "due date" indicated on the system is the date that the bill is scheduled to arrive at its destination. There are two ways payments can be withdrawn from your account depending on who you’re paying. In most cases, funds will be deducted from your account on the pay date you specify. For some billers, such as some small businesses and individuals, a paper check may be sent. In these cases, the money will be deducted from your account at the time the biller deposits or cashes the check. This is no different than if you had written a paper check.
