Wondering how people deal with inventory which is consumed internally. I need to set the items to storeable products so that we can use auto replenishment rules. How do people decrement stock when they are used and not sold? 

Let's say for example, we may use boxes of nails which are issued from stores however we do not sell directly but we do use. How should we decrement the quantity when someone requests a new box? 

Doing an inventory adjustment each time does not seem like the right thing to do.
