I think at all places where rounding is not required for monetary purpose, a flag can be added which when set will round at that place too. for example , at the posting level as you said. > > > - Round after multiplying the cost by the quantity > > > This is required.

So, it does not maintain the balance per commodity if you valuate. The order in which they are added is the order of parsing. If you do not valuate then it will add the quantities according to their respective commodities.
