Item 9.  Regulation FD Disclosure.

            On March 4, 2004, William W. Sherertz, President and Chief Executive
Officer, and Michael D. Mulholland, Chief Financial Officer, of Barrett Business
Services,  Inc. (the "Company"),  will speak to the investment  community at the
Robins Group  "Spot-a-Winner"  Conference in San Francisco,  California.  During
their remarks,  Messrs.  Sherertz and  Mulholland  will comment on the Company's
expected financial performance for 2004:

            o The  Company's  gross  revenues for the first  quarter of 2004 are
            estimated to be $110.0  million,  compared to $101.0 million for the
            fourth  quarter of 2003 and $41.0  million for the first  quarter of
            2003.  Net  revenues  were $36.3  million and $23.4  million for the
            quarters ended December 31, 2003 and March 31, 2003, respectively.

            o  Earnings  per  diluted  share for the first  quarter  of 2004 are
            estimated  to range from $0.00 to $0.05,  compared to  earnings  per
            diluted share of $0.22 for the fourth  quarter of 2003 and a loss of
            $(0.06) per diluted share for the first quarter of 2003.

            The Company changed its reporting of PEO revenues from a gross basis
to a net basis in 2002  because it was  determined  that the Company was not the
primary  obligor  for the  services  provided by  employees  pursuant to its PEO
contracts. Gross revenues information, although not in accordance with generally
accepted  accounting   principles  ("GAAP"),  is  presented  because  management
believes such  information is more  informative as to the level of the Company's
business activity and more useful in managing its operations.  In addition,  the
Company  historically  reported PEO revenues on a gross basis and believes  that
continued  disclosure of gross revenues  information provides consistency in the
Company's financial reporting for comparative purposes.

            A reconciliation of the historical non-GAAP gross revenues discussed
above to net revenues is as follows (in thousands):

            A  reconciliation  of estimated gross revenues to estimated GAAP net
revenues for the first  quarter of 2004 is not  included in this report  because
estimated  PEO  revenues  and cost of PEO  revenues  for the  period  cannot  be
determined without unreasonable effort and expense.

            Statements  in this  report  about  future  events  or  performance,
including  gross  revenues  and earnings per share  expectations  for 2004,  are
forward-looking statements, which



involve known and unknown risks,  uncertainties and other factors that may cause
the actual  results of the Company to be  materially  different  from any future
results expressed or implied by such  forward-looking  statements.  Factors that
could affect future results include economic conditions in the Company's service
areas, the successful  integration of the operations of Skills Resource Training
Center  acquired by the Company on January 1, 2004, the effect of changes in the
Company's mix of services on gross margin,  future workers'  compensation claims
experience,  collectability of accounts receivable,  and availability of funding
for working capital  purposes,  among others.  Other important  factors that may
affect the Company's future prospects are described in the Company's 2002 Annual
Report  on Form  10-K.  Although  forward-looking  statements  help  to  provide
complete  information  about  the  Company,  readers  should  keep in mind  that
forward-looking statements may be less reliable than historical information. The
Company undertakes no obligation to update or revise forward-looking  statements
in this report to reflect  events or changes in  circumstances  that occur after
the date of this report.
