A COMPANY IS BASED IN MUMBAI... IT PURCHASES GOODS FROM GUJARAT AND SALES TO TAMIL NADU, SO IT HAS CST PURCHASE TO CST SALES,

WHAT ARE THE THINGS TO TAKE CARE IN CST PURCHASE TO CST SALES???

HOW TO RAISE SALES INVOICE...?? 

COMPANY BOUGHT "A" @ 100+2% = 102/- FROM GUJARAT AND HAVE SOLD AT 101+2%  TO TAMIL NADU, SO INVOICE TO BE RAISED AT 101+2% OR 103.02/- R.R. SALES??
