Dealing with bad debts

Hello,

I know that there is a work item on the TODO list to add a "bad debt" button, but is there a workaround?

I want to close an invoice as "bad" so that it no longer appears on my list of outstanding invoices BUT I don't want the revenue from that invoice to appear in my "payments received" totals.

Is there any way to do this at the moment before the addition of this new feature?

Thanks!

Mark
