The core concept of business is dropshipping books. The customer would be straightforward, whoever wants to purchase or sell a used book. He/she needs to select the book and if wants to sell it. The customer needs to share the pictures of their books on our app and the system will approve and label the book by their book condition. He has planned to launch with three categories which include Fair, Good, and Excellent. The books will be judged on these criteria and the prices of every category will be different from each other.
