Promotion daily, it’s one way to borrow money (10,5)

I believe the answer is:

commercial paper

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

'one way to borrow money' is the definition.
I can't tell whether this defines the answer.

'promotion daily' is the wordplay.
'promotion' becomes 'commercial' (commercial is a kind of promotion).
'daily' becomes 'paper' (newspaper).
'commercial'+'paper'='COMMERCIAL PAPER'

'it's' is the link.

Can you help me to learn more?
