Any other accounting software I have ever used allows you to put in a "void" date so you can void the check in the period you are actually in.  It then debits the check amount back to the checking account and credits accounts payable and opens the invoice back up for payment.  I have never worked with accounting software that requires you to do all of this manually.  This makes no sense.  It is such a common thing.  I don't understand why Quickbooks hasn't fixed this issue.
