My Friend AS 2 talks about the VALUATION OF INVENTORY and it doesn't speaks about the Head under which Expenditure should be booked....What i could get from ur query is u want to know whether the transportation cost incurred in case of goods sold DIRECTLY, would be included in the COST OF INVENTORY OR NOT..
Answer is "ALL COST INCURRED TO BRING THE INVENTORY TO ITS PRESENT(At the time of Valuation) LOCATION AND CONDITION SHALL BE INCLUDED"
So the cost of transportation in case of direct sale from the transporters will NOT be INCLUDED since it is incurred on goods which YOU HAVE ALREADY SOLD AND SOLD OUT GOODS DOES NOT CONSTITUES YOUR INVENTORY
As far as accounting entry is concerned Freight Outwad is the correct head since it is not only meant for goods sold from the warehouse but would also covers the cases of direct sales..Since the transportation cost incurred in case of DIRECT sale would also be termed as the cost incurred for SENDING THE GOODS and hence Freight incurred on Outward trip..
