We are building a scalable multi-vendor fashion marketplace platform focused on local vendors and location-based product discovery. ! This is NOT a basic WooCommerce setup. Custom development is required. ** Project Overview The platform will allow: Vendors to register and sell products Customers to discover products based on real-time geographic radius Customers to reserve products before visiting physical stores Vendors to receive web and WhatsApp notifications for reservations (!! In future updates we will convert this to a web app and add an Ai feature called AI fashion stylist. AI features are NOT included in this phase. So, make this more mobile responsive) The system must be scalable and REST API-ready for future mobile app development. ** Core Requirements 1. Multi-Vendor Marketplace WordPress (latest version) WooCommerce Dokan Pro (or similar) Vendor registration + admin approval Vendor dashboard Commission system Vendor shop pages Stock management 2. Real-Time Radius Search (Custom Development) User shares GPS location Store vendor latitude/longitude Filter vendors/products within configurable radius (e.g., 5km, 10km) Sort products by nearest vendor Use Haversine formula or equivalent AJAX-based filtering Google Maps API integration !! This must NOT be a basic city filter. We require real distance-based logic. 3. Product Reservation System (Custom Plugin Required) “Reserve” button on product page Temporary stock lock (soft lock) Custom database table for reservations Vendor approval/rejection workflow Auto-expiry after configurable time Restore stock on expiry Prevent race conditions (multiple reservations) 4. Notification System Vendor Web Notifications Real-time dashboard alerts Reservation status updates WhatsApp Notification Integration WhatsApp Business API or Twilio Template-based message sending Triggered on reservation creation ** Technical Expectations Clean, modular architecture Custom plugin development (no theme hacks) Proper use of WordPress hooks and filters Optimized database queries Secure coding practices REST API compatibility VPS deployment ready
