Hi,

One of my friend is doing Pharma - wholesale business.  Their supplier is  giving business incentive of 1.74 lakh based on their offtake for the fiscal 17-18. Usually the supplier  issue a Credit Note to the firm and adjusted the amount in their subsequent purchases (till VAT regeme).  Now in GST is applicable for incentive, they asked a sale invoice from my friend for 1.74 lak + 18% GST.  

Please clarify whether we have to give a sale Invoice / Debit Note for the amount & how it will shown in GST Return and related HSN / SAC Code
