Write "turnover reduced" (4,4)

I believe the answer is:

take down

I'm a little stuck... Click here to teach me more about this clue!

'write' is the definition.
(I know that take down is a more specific form of get down)

'turnover reduced' is the wordplay.
'turnover' becomes 'take' (I am not sure about this - if you are sure you should believe this answer much more).
'reduced' becomes 'down'.
'take'+'down'='TAKE-DOWN'

Can you help me to learn more?

(Another definition for take down that I've seen is " Humble - deflate".)

I've seen this clue in the Evening Standard.
