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.
