                                                           FOR IMMEDIATE RELEASE


              CHECKFREE ANNOUNCES FISCAL 2004 FIRST QUARTER RESULTS
        --Increase in electronic billing and payment access points boosts
                          consumer adoption metrics--
              --Transaction growth modestly ahead of expectations--

          ATLANTA (October 21, 2003) - CheckFree Corporation (NASDAQ: CKFR)
     today announced first quarter revenue growth of 9 percent to $141.3 million
     as compared to the same period last year. The Company's GAAP (Generally
     Accepted Accounting Principles) net loss was $6.7 million or a loss per
     share of $0.07, and underlying net income was $19.4 million, or $0.21 per
     share. Free cash flow was $21.6 million for the quarter, a 50 percent
     increase over the same period last year, as outlined in Attachment A.

          GAAP Results: Net loss for the first quarter was $6.7 million,
     compared to $16.2 million for the same quarter last year. Loss per share
     was $0.07 for the first quarter of fiscal 2004, compared to a loss per
     share of $0.18 for the first quarter of last year. GAAP net cash provided
     by operating activities was $27.0 million for the first quarter of fiscal
     2004, a 12 percent increase over the same quarter last year.

          Underlying Results: Underlying net income for the first quarter was
     $19.4 million, compared to $14.1 million for the same quarter of last year.
     Underlying earnings per share were $0.21 for the first quarter of fiscal
     2004, compared to $0.16 for the first quarter of last year. Underlying net
     income and earnings per share exclude revenue associated with warrants
     issued to a third party, the amortization of acquisition-related intangible
     assets, the cumulative effect upon adoption of SFAS 142, and related income
     tax benefits. A reconciliation of CheckFree's underlying results to its
     GAAP results is included in Attachment A.

          "We experienced consistent performance across all business units this
     quarter, with each contributing according to plan," said Pete Kight,
     CheckFree Chairman and Chief Executive Officer. "Specifically, in our
     Electronic Commerce division we saw all of our distribution channels
     contribute to the growth of key payment processing and electronic bill
     delivery metrics. Accelerated growth in both access points and consumer
     adoption reflects the strength of these results. In our Investment Services
     business, we saw a slight lift in portfolios under management for the first
     time in some time -- a good sign for a market that has been challenged by a
     weakened economy in recent years."

          "Our expanded international presence for enterprise reconciliation
     solutions and growing interest in our electronic check conversion solution
     contributed to our execution in a traditionally slow sales quarter for our
     Software business," Knight continued. "These collective results position us
     well for the remainder of fiscal 2004 and set a solid foundation on which
     to build and strengthen our market position as the financial e-commerce
     leader."

          The Company also reported that its Electronic Commerce unit processed
     126.7 million transactions for the quarter, a 5 percent increase over the
     previous quarter; delivered 14.7 million electronic bills, an increase of
     27 percent over the previous quarter; and increased the number of fully
     enabled electronic billing and payment distribution points to more than
     1,000. In its Investment Services unit, CheckFree signed three clients to
     its Multiple Strategy Portfolios solution, and increased portfolios under
     management from more than 1.2 million to 1.3 million during the quarter. In
     its Software business, CheckFree expanded its U.K.-based sales presence to
     include enterprise reconciliation through its RECON-Plus Frontier solution.
     Refer to Attachment B for details on the financial performance of
     CheckFree's divisions in the first quarter of fiscal 2004, and Attachment C
     for core electronic billing and payment metrics.

     EXPECTATIONS FOR SECOND QUARTER AND FISCAL YEAR

          "For the second quarter of 2004, we project revenue in the range of
     $143 to $148 million, and GAAP earnings per share in the range of $0.01 to
     $0.04," said CheckFree Chief Financial Officer David Mangum, "This equates
     to underlying earnings per share in the range of $0.22 to $0.24."

          "Sequential quarterly transaction growth for the second quarter should
     be in the range of 4 to 6 percent, reflecting solid growth across all
     distribution points and expected additional in-house runoff," Mangum
     continued. "We anticipate improved seasonal performance from our Software
     division and incremental progress from our Investment Services unit."

          "Our full-year guidance on earnings per share remains unchanged at
     breakeven to modestly positive on a GAAP basis, or $0.93 to $0.97 on an
     underlying basis; and we expect free cash flow to continue on track, with
     growth approaching 20 percent," Mangum concluded.

          The difference between GAAP and underlying earnings is due to
     acquisition-related intangible amortization expense.

     USE OF NON-GAAP FINANCIAL INFORMATION

          Management evaluates the operations of the Company using the metrics
     of underlying income, underlying earnings per share, and free cash flow.
     These non-GAAP financial measures exclude or include items that represent
     either non-cash charges that do not impact the Company's free cash flow, or
     other items, which are evaluated separately as they arise. Therefore, the
     Company believes that its underlying results and free cash flow
     calculations provide useful information to investors because they are
     consistent with its internal performance measurements. Further, the Company
     considers free cash flow to be a measure of liquidity and believes that it
     provides useful information to management and investors about the amount of
     cash generated by the Company after the acquisition of property and
     equipment, which can be used for strategic and other purposes. CheckFree's
     underlying results and free cash flow are not prepared in accordance with
     GAAP. These measures should be considered in addition to, and not as a
     substitute for, our GAAP results.
