The most important thing to understand is when the bill will be received, not how it will be paid. Payment methods are determined by the relationship between Fiserv and the biller, and are subject to change. When scheduling a payment, the system automatically pre-fills the earliest payment date the biller can receive the payment. The date can be altered to a future date, but not an earlier date. Once a payment begins processing, you will be able to view the payment method in the history. If the item is a member draft, stop payments should be placed like any other member draft. The check number can be viewed in the history. If the item is electronic, a case will need to be created through Customer Care.
