Count as business (6)
I believe the answer is:
matter
I believe this clue is a double definition.
'count' is the first definition.
(I know that count can be written as matter)
'business' is the second definition.
(business can mean some matter or situation)
'as' is the link.
(Other definitions for matter that I've seen before include "Concern" , "Issue - stuff" , "Be of significance" , "See 10" , "It occupies space, has substance" .)
