I have a similar issue - a customer paid his invoice from my email (view and pay link). His payment was returned (reason - R03). I even didn't apply his payment to his invoice yet, so in my books the invoice is open. But when I send it to him - it shows it's paid. All answers above do not explain how to make that invoice open again in the link that we send to them. Why our customers see invoices as paid when it's clearly not.

Do I create another invoice? How to make that returned payment link to that invoice and make it open again? Answers like "upapply payment" don't work because the payment hasn't been applied yet. I had this issue before and my customer ended up sending me a check, but it was inconvenient for them.

Thank you in advance.
