It is unbelievable that QB does not have the capability of posting an invoice to the GL in a different period than the invoice date.  This is accrual accounting 101.  It is also unbelievable that this functionality has not been added even though the original post was made over a year ago.  This is a major flaw in QB and in my opinion is justification for anyone considering using QB to choose another solution.  Come on QB......FIX THIS ISSUE!!
