Smart Agricultural Marketplace: A Mobile-First Digital Platform for Direct Farmer-ro-Buyer Trade with Real-Time Pricing and UPI-Based Payments

Many farmers in India find it hard to sell their crops at a good price. They often depend on middlemen. They do not always know the prices in other markets. Payments can also come late. In this paper we describe the Smart Agricultural Marketplace. It is a mobile app that lets farmers and buyers deal with each other directly. Farmers list their crops. Buyers search the list and send requests or bids. The app also shows market prices and supports UPI payment. We plan to build the app with Flutter, and to use Firebase and Node.js for the backend. The app will work in more than one language, including Kannada and English. So far we have built a web prototype. It shows the seller and buyer screens: listing a crop, searching crops and tracking requests. Payment, live market prices and testing with real farmers are still to be done. We hope the app will help farmers find buyers, compare prices and sell with more confidence
