      On February 2, 2004, Quality Systems, Inc. (referred herein to as the
"Company," "Registrant" or "QSI") held a conference call concerning its
financial performance for the quarter ended December 31, 2003. A transcript of
the conference call is attached to this Form 8-K as Exhibit 99.1. The conference
call contains forward-looking statements regarding QSI and includes cautionary
statements identifying important factors that could cause actual results to
differ materially from those anticipated.

Use of Non-GAAP Financial Measures

The Company from time to time discloses its Days Sales Outstanding ("DSO") which
is a Non-GAAP financial measure. During the quarter ended December 31, 2003, DSO
was 108 days. The Company calculates DSO as follows: Net revenue for the quarter
is annualized (multiplied by four) and then divided by 365 days to yield an
average daily sales amount. The balance of accounts receivable net of any
reserves for bad debts is then divided by that average daily sales amount
resulting in a DSO figure. For the quarter ended December 31, 2003 the
calculation was as follows:

Quarterly Revenue:                  $18,199,000

Annualized (X 4):                   $72,796,000

Divided by 365:                     $199,441 = Average daily revenue

Net Accounts Receivable :           $21,545,000

Divided by average daily revenue:   $199,441

Equals:                             108 days (rounded)

The Company believes the use of DSO provides useful information to investors
regarding the Company's ability to convert its receivables into cash. DSO thus
provides more detailed


                                       2


information regarding the Company's financial results than the financial
measures calculated and presented in accordance with GAAP.
