According to MSFDC's Warren Dent, the bulk of the cost is funded by billers who save on the expense of processing bills. However, some financial institutions may charge consumers fees for paying bills not part of the presentment system.

And of course, banks will still charge fees for bill payment. For example, Chase charges $2.95 a month for bill payment and $0.50 for each bill paid. Like most banks, Chase will waive this fee for certain high balance accounts. But those costs are likely to be recouped elsewhere in online banking fees. Consumers should ask about fees before signing up.
