Invoice due date per supplier

I want to enter the invoice date and supplier, but different suppliers have different terms.
How do I get the terms and due dates to auto generate?

You'll need to post a sample workbook showing a mock-up of what you are after.

Eg. RSEA terms are 30 days but Bunnings Trade is 30 days End of Month
I would like the due date to automatically calculate once the supplier is selected.
