COGs being discounted in QBO

The cost of an inventory item which is sold is determined by the purchase price.  Not the cost you "set up"

It could be due to the fact that QBO uses the FIFO method of inventory costing.  QBO sells the items you received into inventory first.  So, for example, if you received the same item at $50, then at $55 & finally at $60, it will sell the $50 items first even though you paid $60 for the most recent purchase of that same item.
