Treasury management - Credit rating check?

Hello everybody,

 

I am ICAEW ACA student and I have a question which need your advise.

 

Regarding Treasury management, as long as I know, we can check customer's credit rating through Trasunion, Experian.. However, I hold no experience in doing it. Is it high costly? and how much? Are there any alternative ways?

 

Thank all of you in advance!
