what is sale value?

dear friends happy new year.

The company sells goods on "freight to pay" basis. When they raised the invoice they deduct the freight amount paid by the purchaser.
Ex:- The invoice appear as follows.

10kg*Rs.1000/= 10,000
                          _________
                      total 10,000

             Less: freight 1000
                            _________
                               9000
                           _________
Now my doubt is, is it enough to recognise 9000 as sale or,
recongnising sale for 10000 and freight 1000. suggest me.
