'going out of business only going through' is the definition.
I can't judge whether this defines the answer.

'my cash' is the wordplay.
'my' becomes 'folding' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'cash' becomes 'money' (I've seen this before).
'folding'+'money'='FOLDING MONEY'

Can you help me to learn more?

(Another definition for folding money that I've seen is " Bank notes".)

I've seen this clue in The Telegraph.
