BidNexus-online auction system

Abstract

In the digital commerce era, online auction platforms have emerged as powerful tools for dynamic pricing and competitive purchasing. This paper presents BidNexus, a comprehensive online auction system that bridges the gap between sellers and buyers through a secure, real-time bidding environment. The system is structured into three key modules—Seller, Buyer, and Admin—each providing role-specific functionalities. Sellers can list products by uploading images, videos, and 360-degree views, and set custom auction schedules. Buyers receive timely notifications through email and WhatsApp, including alerts one day before and at the start of auctions they have subscribed to. Live bidding ensures fair competition, and a leaderboard highlights the top 10 highest bidders based on bidding activity. Post-auction, winners receive email confirmations along with secure payment gateway links, from which the platform deducts a 5% commission. Admins play a critical governance role, handling user behavior and resolving disputes, including blocking fraudulent or non-compliant users. The platform is tailored for the Indian market, with full support for INR transactions and strict exclusion of electronic and machine-based products. BidNexus ensures a transparent, engaging, and trustworthy auction experience for all stakeholders.
