Goes ahead, making profit (8)
I believe the answer is:
proceeds
I believe this is a double definition.
'goes ahead' is the first definition.
(I've seen this before)
'profit' is the second definition.
(I've seen this before)
'making' is the link.
(Other definitions for proceeds that I've seen before include "Income, from an event say" , "Moves ahead, goes forward" , "Returns" , "Profit" , "Starts lawsuit" .)
