Bill to ship to transaction in gst

Thank you Sir. i have read section 10(1)(b) of IGST Act, it provides clarification regarding place of supply.

But major issue in this transaction is that i don't want to disclose my purchase price to party C. 

So, what document / which invoice will be accompanied in transportation of the goods by party A to party C in compliance with e-way bill provisions.

Say to A make bill on actual price should be charged by u from c and take credit note of discount from A for urself on difference... Like u want to sell the products to C on Rs. 120....but ur actual purchase price is Rs. 100...so tell to A that make bill of Rs. 120 in name of C under bill to ship and take Rs. 20 credit note in ur name as post sale discount... Hope u understand my point... And generate e way bill through online... Invoice and eway bill no is sufficient documents... And mam one thing i am not sir😀😀

THANKS A LOT

YES SOLVED SIR, THANKS AGAIN
