Hello,

I have received one request to create a new payment term with the below requirement.

Create new payment terms of China OU:30%prepay (due date: 10 days);55%paid on delivery (due date: 30 days);15% set up & acceptance (due date: 90days)

Any one has an idea how much percentage and values need to give to define payment term with the above requirement?

Thanks.
