It would be very helpful to not allow everyone to be able to change a price/cost on an item. it is often that a price is changed and then there is a typo that is not caught and sent to a client that way. Also, the system should not allow a price to be less than the cost. We often find that when someone is rushing and changes these amounts the numbers may not go in correctly and it leaves us with it costing us and not the client for that item. or they change the cost and do not update the price and then it costs us money to sell that item.
