               Daleen Reports Third Quarter 2003 Operating Results
     Revenues Increase for Fourth Consecutive Quarter; Net Loss Down By 74%


BOCA  RATON,  Fla.  -  October  27,  2003 - Daleen  Technologies,  Inc.  (OTCBB:
DALN.OB),  a global  provider of licensed  and  outsourced  billing and customer
management,  operational  support systems (OSS) and revenue assurance  solutions
for traditional and next generation service  providers,  today reported revenues
of $4.9 million for the third  quarter of 2003,  a 17% increase  over its second
quarter 2003 reported  revenues of $4.2 million.  Net loss for the third quarter
was $371,000,  or $0.01 per share,  a decrease of 74% over the $1.4 million,  or
$0.03 per share loss reported in each of the first and second  quarters of 2003,
and compared to a $1.7 million net loss, or $0.07 per share in the third quarter
of 2002, prior to Daleen's  acquisition of the assets and certain liabilities of
Abiliti Solutions.

     "Throughout  this year,  we have  maintained an intense focus on leveraging
our products,  delivery  channels and technical  expertise to drive  incremental
revenue growth from our current and new customers," said Gordon Quick, president
and CEO of Daleen.  "We believe these efforts,  and our improved business model,
have had a significant and positive impact on our results,  and will continue to
foster healthy growth for Daleen."

Third Quarter Highlights

o    Revenues increased for the fourth consecutive  quarter, as a result of work
     related  to  recent  contracts,   professional   services  engagements  and
     outsourcing  services.  Daleen's  RevChain(R)  implementation  for  ETB  in
     Bogota,  Colombia,  which was  announced in June 2003, is fully staffed and
     the project is progressing as expected.

o    Revenues from Daleen's core customer base remain  strong.  During the third
     quarter,  Daleen was engaged in active professional  services work for more
     than 50% of its current  customers,  not including  service  bureau clients
     supported  through  BillingCentral(R).   Additionally,  Australian  telecom
     carrier  AAPT  signed a two-year  contract  for the  continued  support and
     maintenance of its RevChain platform.

o    Total expenses were $5.3 million for the quarter,  compared to $5.7 million
     and $5.6 million, respectively, for the second and first quarters of 2003.

o    The  company's  total cash and cash  equivalents  used in the quarter  were
     $530,000,  compared to $1.4  million  and  $500,000,  respectively,  in the
     second and first  quarters of 2003.




o    Daleen  expanded  its  long-standing  strategic  partnership  with Danet to
     collaborate in bringing  practical,  ROI-driven  revenue assurance and cost
     management solutions to convergent telecom service providers, including the
     new Asuriti(TM) software and Danet's financial assurance solutions.

o    Daleen  delivered   Release  6.0  of  its  RevChain  billing  and  customer
     management  software.  RevChain  6.0 offers  performance  improvements  and
     expanded  rating and  discounting  capabilities  that are  designed to give
     service  providers  more  flexibility  in  supporting  loyalty  groups  and
     affinity marketing.


     "This  was  a  strong  quarter  across  the  board,  as  evidenced  by  the
incremental revenue growth, reduced expense levels and a significant decrease in
our net loss," said Jeanne Prayther,  chief financial officer for Daleen.  "More
importantly,  the  cumulative  results  we  have  achieved  through  consecutive
quarters of revenue  growth and sustained,  effective cost  management are a key
factor in driving our business toward a positive cash flow position."
