However, the valid question is raised-- if an invoice is voided in a different accounting period (say issued on Dec 30th and voided on Jan. 1st after other invoices were sent out which substnatially change the COGS per unit), when exactly does the adjustment get posted?
Well usually at that point, you wouldn't void then invoice because the books are closed on the year. You would apply a credit.
