Comprehensive Offline Product Price Comparison Platform

I need a responsive platform focused on offline product price comparison with the following features: 1. Customer Login: - OTP-based login. - Wishlist and recently viewed products. - Compare products from multiple shops. - Enquiry tracking and notifications. - Option to report incorrect pricing or product information. 2. Seller Portal: - Monthly subscription status and renewal system. - Lead management dashboard. - Product upload via Excel, including bulk price updates. - Enquiry conversion tracking. - Analytics to track profile visits and product views. - Option for featured listing promotion. 3. Seller Staff Permissions: - Allow primary sellers to create staff accounts with granular permissions for: * Listing management. * Price updates. * Enquiry management. * Dashboard viewing. 4. Admin Panel: - Seller KYC & GST verification. - Duplicate listing detection. - Subscription and payment management tools. - Seller performance analytics (e.g., city-wise and category-wise breakdowns). - Customer complaint management system. - Ability to manage promotional banners and feature select shops/products. This project will initially focus on basic functionality but should be built keeping future scalability in mind.
