Company, firm (8)
I believe the answer is:
business
This clue is a double definition.
'company' is the first definition.
(I've seen this before)
'firm' is the second definition.

(Other definitions for business that I've seen before include "complicated problem" , "Work - shop" , "Company U occupation" , "Commercial or industrial enterprise" , "Occupation; trade" .)
