Online Bidding System using Spring Boot, React JS & MySQL

The Online Bidding System or Online Auction System Project using Spring Boot & React JS ensures a seamless experience for all involved. As an Admin, Admin can add the Product Categories into the System, so that Seller can sell the products from these Categories only. The Customer can register & log into the system by himself. Now the Customer can Buy or Sell the products with the same login, each customer will have their own Wallet in which they can add their money.

The Customer can add the product into the system for selling his product by entering the correct details such as name, category, asking price & product end time. Once the Seller adds the product into the system, it will be visible on the website Home Page and now the Buyer can Bid on the product and before bidding on the product, the buyer should have Sufficient Balance in his wallet. Buyers can Bid on the product till the product's expiry time.

After the product expiry, it will automatically get allocated to the highest bid buyer. Once the Product is allocated to the Buyer, the Seller will be able to see the Buyer's details and now the Seller can assign this product order to the delivery person for the Product Delivery to the Buyer. After this Delivery Person can log into the system and update the Order Delivery Status and the same thing will be visible to the Buyer and Seller.

In the end, the Admin can see the complete details about the Products, Sellers, Sellers Delivery Persons, Buyers, etc.
