Fiserv Inc. of Brookfield, Wis., said it has renewed a contract with National Penn Bancshares Inc. of Boyertown, Pa., which will add small-business bill payment to its online banking service.

The $9.2 billion-asset National Penn also will use CheckFree Builder, a suite of Web service components, to streamline the online bill payment enrollment process for its network of banks, Fiserv said Tuesday. Fiserv acquired CheckFree in December of last year.

National Penn, which has been a Fiserv client since 1999, uses CheckFree Web RXP, which includes such services as payment reminders and recurring payments features, the vendor said.
