Due date different from billing cycle.
I like to have products billed for 1st-30th each month with due date the 11th and invoices send on 1st each month.
All i manage to get is:
1 - A product billed from 1st-30th but with date the 1st. and invoice sent 10 days before. (20th of previous month)
2 - A product billed from 11th-10th(nextmonth) with due date the 11st. and invoice sent 10 days before. (1st of current month)
