GRH89:
If you are using account 688 to book purchase discounts (instead of 687 which is where they should go according to GM standard accounting manual) where are you booking appreciation and/or depreciation from your monthly price update tapes (this is what account 688 is intended for according to the same manual)? Where are you booking the discount from GMSPO parts invoices to? If you do as suggested in the above post by Gerry Laughlin and book the premium paid to another dealer for warranty parts to account 680 (cost of warranty parts sales), this gives you a much more accurate picture of how profitable your warranty sales really are. Otherwise, it just gets buried along with everything else that legitimately should go to purchase discounts (687). This also gives a much more accurate picture as to whether your inventory is generating profit or if you are living off of other dealers' inventories.
