This option may be necessary in addition to Option #3 if both the sale and cost are needing adjustments. You would use this method alone if ONLY the Vendor Order needs adjustments.

If the “change order” falls into the “Punch List” category be sure to follow all recommended guidelines here for Punch orders.
