Recently i am preparing for IPCC MAY 2012 EXAM. but i have problems in following point so, please help me.

 

 

I have doubt in following point of SERVICE TAX.
1.   what is the different between BILL RAISE & BILL ISSUE. 
2.  is it service tax is includes in BILL RAISE , BILL ISSUE & ADVANCE PAYMENT to service provider. 
 
I refer PADUKA  for service tax. I solve many examples of  service tax. but I confuse about above point. In some example service tax is calculated separately and in some example service tax is considered as including in bill amount. 
 
Please give me reply as soon as possible
