Money-making bill covered by biography (10)
I believe the answer is:
profitable
'money-making' is the definition.
(similar in meaning)
'bill covered by biography' is the wordplay.
'bill' becomes 'tab' (tab is a kind of bill).
'covered by' means one lot of letters goes inside another.
'biography' becomes 'profile' (profile is a kind of biography).
'tab' put within 'profile' is 'PROFITABLE'.
(Other definitions for profitable that I've seen before include "offering good returns" , "Cost-effective" , "useful" , "Rewarding" , "Money-spinning" .)
