If you want to start an online business, Etsy is the platform for you. The best part is you do not even have to sell your own products and take the pain of shipping product. You can easily connect Printify or Printful with your Etsy account and sell the products on Etsy that you design on Printify and Printful. When someone orders from your Etsy shop, Printify/Printful creates your product and then ships. You pay to Printify when you get an order. So you basically pay your supplier only when you sell. With this method your only cost will be product listing and advertising, if you are running paid ads.
