Pick one product you can source reliably, register the business, start selling on a marketplace, then add your own store. In order: register for free on Udyam as a sole proprietor or set up a company; get a GSTIN on gst.gov.in (no government fee, and Amazon and Flipkart need one for most categories, while Meesho also accepts a PAN-based Enrolment ID for sales within your own state); open a current account; list on a marketplace, where Flipkart charges 0% commission on products under ₹1,000 and on all fashion, Meesho charges 0% commission on everything and Amazon shows zero referral fee on over 12.5 crore products; then add your own Shopify store (₹1,994 a month, or ₹1,499 billed yearly) with Razorpay at 2% plus GST and Shiprocket's free Lite plan for shipping. Price every product after marketplace closing fees, shipping and returns, not before. The rule: get repeat buyers on one channel before opening a second.
