we are exporting materials to abroad countries.In this regard first we prepare commercial invoice in foreign currency.
Then prepare tax invoice in INR.
While preparing commercial inv.in foreign currency we take reference for rate ( INR to foreign currency) from oanda currency converter.
This method is ok or shipping bill rate method is ok.

Which is authentic method for rate for export rate
Example
Oanda currency rate 82
shipping bill rate 81
