I have to send invoices that are due on specific dates rather than in a specific time period like net 30/net 60.  How do I change the preferred terms to say that it is due on that day? 

For example, I create an invoice in January for a payment that is due August 14 and I don't want the invoice to say Due on Receipt or Net 30/Net 60.  How can I change the preferred terms to reflect this?

TIA for any assistance.
