CheckFree launched the first fully integrated Electronic Bill Payment and Presentment (EBPP) solution, E-Bill, in March 1997. E-Bill enabled billers to present bills electronically and to receive payments electronically. E-Bill was first implemented as a “thin” consolidator model, but was later extended to support the “thick” model and even a direct billing model. E-Bill enabled billers to track events related to presentation and payment, to dynamically adjust fields, and to draw consumers to specified URLs on their Web sites depending on bill summary data. In spite of these capabilities, CheckFree was a batch processing service because of its dependence on the ACH, which required two to four days to process transactions. CheckFree’s average cost of presenting a bill was 15 to 20 cents.
