Hi Johnny,
I have done this with several customers now. The screenshot you shared above is the preliminary setup done in Credit and collections parameters. On the customer, you can find this information in the Related Information tab on the right side of the screen.

You will have to refresh it to see the information, but it will provide it on the spot.
As for calculating DSO for risk management, here are the instructions on Docs:
