drawing account

I'm a little stuck... Click here to teach me more about this clue!

'business ledger' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'sketching a cold nobleman's' is the wordplay.
'sketching' becomes 'drawing' (I've seen this before).
'cold' becomes 'C' (eg on taps).
'nobleman' becomes 'count' (count is a type of aristocrat).
'drawing'+'a'+'c'+'count'='DRAWING ACCOUNT'

Can you help me to learn more?
