Invoice a cold aristocrat (7)

I believe the answer is:
account
'invoice' is the definition.
(synonyms)
'a cold aristocrat' is the wordplay.
'cold' becomes 'c' (abbreviation, eg on taps).
'aristocrat' becomes 'count' (some European aristocracies have counts).
'a'+'c'+'count'='ACCOUNT'
(Other definitions for account that I've seen before include "Charge" , "Bill; description" , "Narrative or invoice" , "Financial statement" , "judge" .)
