Assuming responsibility and accepting payment (6,6)

I believe the answer is:

taking charge

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

'accepting payment' is the definition.
I can't tell whether this defines the answer.

'assuming responsibility' is the wordplay.
'assuming' becomes 'taking' ('take' can be a synonym of 'assume').
'responsibility' becomes 'charge' (I've seen this in another clue).
'taking'+'charge'='TAKING CHARGE'

'and' acts as a link.

Can you help me to learn more?

I've seen this clue in The Globe and Mail.
