I am trying to set up payment terms so that invoices are due on the 15th of the month following the month they are incurred.  Invoices are generated throughout the month, the statement is sent out the following 1st of the month and it is due on the 15th.  The problem I am having is that with a setting of Net 15, invoices generated prior to the 15th of the month are showing up as past due on the statement. I've been trying to create a new term of "due by 15th of next month" but need some guidance on the settings.

Example: Invoice created November 8, 2020. Statement generated December 1, 2020, with a due date of December 15, 2020, shows the invoice as already past due.
