             Let us assume that you have raised an invoice for a value of Rs.10,000/- and charged service tax of Rs.1,236/-.  
If you are clinet pay no amount there is no liability on you.
If he pays an amount of Rs.5,000/- only,  treat the realised amount as cum-tax and pay  service tax.
BUT WHY WASTE SO MUCH VALUABLE FORUM SPACE?
