It would be helpful for the Customer Due Date to auto-populate from the date the quote is approved or payment is made, with override ability. Example, Customer John approves the Quote and provides payment, the Quote moves to an Invoice and the Customer Due Date field populates with a pre-set time period, for example 10 business days. This also helps with pulling weekly analytics. Currently, if you run a revenue report, it counts the revenue based on the invoice date which is often weeks before when the deal actually closes.
