Approach relation to make profitable (4,2,7)

'profitable' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'approach relation to' is the wordplay.
I cannot really understand how this works, but
'relation' could be 'account' (account is a kind of relation) and 'account' is located in the answer.
'to' is present in the answer.
The remaining letters 'turn' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

'make' acts as a link.

Can you help me to learn more?
