Date Issue In A SQL 2005 Scheduled Job

I have a job in SQL 2005 that when it runs works fine if I hard code the  Makedate, what I need it to do is have the Makedate equal  todays date minus one day...I came up with the code below, but that does seem to work...any thoughts.

 INSERT INTO abcTransaction
(
    Payee,
    Payment,
    AccountNumber
)
SELECT
    'Credit',
    SUM(Rebate * Quantity),
    A.AccountNumber
FROM
    Account A
INNER JOIN
    abdTrades T on A.AccountNumber = T.AccountNumber
Where MakeDate = getDate() - 1
 

GROUP BY
    A.AccountNumber
