Cope with success that's netted Bill a thousand (4,2)

'cope' is the definition.
(I've seen this in another clue)

'success that's netted bill a thousand' is the wordplay.
I cannot really understand how this works, but
'bill' could be 'ac' (short for account) and 'ac' is found in the answer.
'thousand' could be 'k' (synonyms) and 'k' is found in the answer.
'success' could be 'hit' (a hit is a commercial success) and 'hit' is located in the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).

'with' acts as a link.

Can you help me to learn more?
