BillMatrix, a Fiserv-owned service, is a third-party electronic bill payment processor used by utilities, telecommunications, and financial institutions to let customers pay bills by phone, online, or through authorized retail locations. It processes payments via credit card, debit card, or ACH bank transfer for major billers like Georgia Power and Mississippi Power.

Use Fluz to maximize rewards on your BillMatrix bill payments. Instead of paying your utility or loan bill directly through BillMatrix, buy a Fluz gift card for the amount due and use it to complete your payment, earning cashback on a bill you're already paying. Fluz stacks with other rewards programs, so you can layer this cashback on top of anything else you're earning. It's a simple way to add extra value to a routine utility or bill payment, with cashback credited straight to your Fluz wallet.
