   CONCUR TECHNOLOGIES ANNOUNCES PRELIMINARY FOURTH QUARTER FINANCIAL RESULTS
                       Tuesday, October 5, 1999 08:06 AM

     REDMOND, Wash. -- (BUSINESS WIRE) -- Oct. 5, 1999 -- Concur Technologies,
Inc. (Nasdaq: CNQR), the global leader in workplace eCommerce solutions, today
announced that based on a preliminary analysis of results of operations, the
company expects to report total revenues for the fourth quarter of fiscal 1999
in the range of $8.6 million to $9.2 million, which includes approximately $5.0
million to $5.3 million in license revenues.

     This compares to securities analyst estimates of approximately $12.3
million to $12.7 million for total revenues, which includes license revenues of
approximately $8.1 million to $8.8 million. For the fourth quarter of fiscal
1998, the company reported total revenues of $6.3 million, which included
license revenues of $3.9 million. These preliminary results are subject to final
analysis and audit. Full fourth quarter and year-end results will be reported on
Wednesday, October 27, 1999.

     "Revenues for the fourth quarter, particularly license revenues, were
significantly below expectations, primarily due to an unexpected delay in
closing quarter-end business," said Steve Singh, Concur President and Chief
Executive Officer. "In addition, the three months ended September 30 marked the
first quarter in which we included three products within our suite of workplace
eCommerce applications. Our products now impact a broader range of departments
within companies, and customers need additional time to evaluate the strategic
benefits of purchasing our suite of workplace eCommerce solutions, thereby
somewhat lengthening the sales cycle."

     "Despite these disappointing results, we remain confident in our business,
the demand for our products, the strength of our suite of applications and in
our ability to execute on our workplace eCommerce vision. I am very pleased to
announce that we will unveil another component of this vision tomorrow with the
launch of our Internet-based eWorkplace.com(TM) products, which allow us to
expand our reach into the small and middle market, opening a significant and
untapped market," added Mr. Singh.
