The platform starts with the segregation of buyer and sellers and then their signup. After successful signup, only the seller will have the privilege to add the products, their categories and all the relevant details. Once done, the buyers will be shown all the products that have been uploaded by the respective sellers and thus will have the option to add the products to the cart.
