Invoice Due Date Before Invoice Date
Just wanted to make a suggestion to remove the rule that stops you setting the due date on an invoice before the invoice date.
We make custom goods for customers and generally requirement payment before the date of delivery. While we add a comment to this effect if we make the invoice date the date the goods will be collected/delivered we cannot make the payment date any earlier.
I don't want to get into the accounting - but for simplicity it makes a lot more sense to record the invoice date on the date of delivery to ensure the sales are in the correct period for accruals. It is much easier to handle the reallocation of deposits, rather than accruing of sales...
