Company takes in some cash (4)
I believe the answer is:
coin
'some cash' is the definition.
(thesaurus)
'company takes in' is the wordplay.
'company' becomes 'co' (abbreviation).
'takes' says to put letters next to each other.
'co'+'in'='COIN'
(Other definitions for coin that I've seen before include "Make up" , "Metal used as money" , "Think up" , "Invent (a new word)" , "American quarter, for example" .)
