....Hi, I started a new online pharmacy recently. Got it incorporated 15 days back. I have tied up with a local retailer for my stock where he gives me the best margins. I get orders from online and the retailer processes it and I deliver them. I deliver them with his name along with mine on the invoice as invoice needs drug licence as a mandatory. I have a couple of doubts. 1. Basically, he is not selling goods to me, he is selling to my customers. I am just doing delivery service here. How can I calculate taxes here and how much? 2. He does a business of more than 20L/ annum because he is supplying me. So he has to pay GST now. Because he is not earning anything from me, how can he avoid paying tax? 3. In how many days he has to claim GST returns as all his vendors charge 12% GST on average on all the invoices made(He already has GST No). Thanks in advance.
