           in Item 12 of this Current Report on Form 8-K.

ITEM 12.  RESULTS OF OPERATIONS AND FINANCIAL CONDITION.

         On October 21, 2003, CheckFree Corporation ("CheckFree") issued a press
release announcing its financial results for the first quarter ended September
30, 2003, and its expectations for the second quarter ended December 31, 2003
and fiscal 2004. Pursuant to General Instruction F of Form 8-K, a copy of such
press release is furnished as an exhibit to this Form 8-K and is incorporated
herein by reference. The information in this Form 8-K, including the exhibit
hereto, shall not be treated as "filed" for purposes of the Securities Exchange
Act of 1934, as amended.

         CheckFree will host a conference call at 5:30 p.m. (EDT) on October 21,
2003 to review its financial results for the first quarter ended September 30,
2003, and its expectations for second quarter ended December 31, 2003 and fiscal
2004. To phone into the conference call, dial 1-800-243-6403 anytime after 5:15
p.m. (EDT) and ask for the conference call hosted by Peter Kight. CheckFree will
also broadcast the call on the Internet. The live conference call will be
accessible through the Investor Center section of the CheckFree corporate Web
site at http://www.checkfreecorp.com. A digital replay of the call will be
available on the same Web site after 7:30 p.m. (EDT).

         Certain of the CheckFree's statements contained or incorporated by
reference in this Form 8-K are not purely historical, and as such are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. These include statements regarding management's
intentions, plans, beliefs, expectations or projections of the future, and
include statements regarding forecasts and expectations of revenue, earnings,
cash flows, sequential transaction growth for the second quarter of fiscal 2004
and fiscal 2004 as a whole, and consumer adoption of electronic billing and
payment services. Forward-looking statements involve risks and uncertainties,
including without limitation, the various risks inherent in CheckFree's
business, and other risks and uncertainties detailed from time to time in
CheckFree's periodic reports filed with the Securities and Exchange Commission,
including its Form 10-K for the year ended June 30, 2003 (filed September 15,
2003). One or more of these factors have affected, and could in the future
affect, CheckFree's business and financial results in future periods, and could
cause actual results to differ materially from plans and projections. There can
be no assurance that the forward-looking statements contained or incorporated by
reference in this Form 8-K will prove to be accurate, and issuance of such
forward-looking statements should not be regarded as a representation by
CheckFree, or any other person, that the objectives and plans of CheckFree will
be achieved. All forward-looking statements contained or incorporated by
reference in this Form 8-K are based on information presently available to
management, and CheckFree assumes no obligation to update any forward-looking
statements.
