Hi
Just a little difficult without knowing the layout of your data, but
supposing that Column D hold Invoice date and column E holds Payment
Date, then the following should work

=AND(E1="",D1<Today()-N1)
Any invoices that are paid will have entries in Payment Date hence would
be ignored.
Change references to suit your data.
