I have review all of the methods listed in this forum for sending invoices marked as paid, and none of them work for me. Even though the invoice shows as "Paid in Full" on my screen, sending the invoice to clients through any of the methods listed here simply sends them a new invoice requesting the total. There is no "paid" invoice showing up to be sent, rather, the same invoice I sent originally for the total, and sending does not send anything marked as paid even though it shows as paid when I open it myself. I have a Mac if that makes a difference.
