REGARDING RAISING OF SERVICE BILL

what is your problem, query, question,

pl elaborate

I JUST WANT TO KNOW THAT IS IT OK THAT I AM RAISING THE OUTPUT BILLS ON SAME PRICE OF PURCHASE FOR ACHIEVING TARGET ND AFTER MONTH WE RAISE THE INVOICE OF INCENTIVES WHICH IS AROUND 3PERCENT IF THE PURCHSE PLUS 18 PERCENT GST 

per my opinion, it is ok as you raise separate bill for your mark up.

BUT THE MAIN QUESTION IS WHETHER GST AUDITORS HAVE PROBLEM THAT THE PURCHASE AND SALE BOTH TAXABLE VALUE IS SAME SINCE FOR ACHIEVING THE TARGEST WE HAVE TO SALE IN SAME RATE AS WE PURCHASED    

BUT ON ACHIEVING TARGETS WE GOT INCENTIVES THAT WE RAISE THE BILL AGAINST THE COMPANY WITH 18% GST.
