Well I just wasted 2 hours of my morning trying to figure this out.

I ended up here via a Google search.

I have tried every suggestion posted here and the obnoxious red PAST DUE still appears on every invoice.

Granted, it is only on my screen. I cc myself with all invoices I send out so after apologizing to one customer for the PAST DUE notice I opened the invoice and seen that it wasn't on the copy I cc'd myself.

This is still unacceptable in my opinion, I don't want to see PAST DUE on my invoices even if it is not on the invoice being sent out.

I will be looking for a different accounting program next time around.

I run a small business from my home, no employees so the program is overkill for what I actually need but I have been using it for around 15 years now simply for the ease of processing credit cards.
