Multi-Vendor Location-Based Marketplace - Responsive WordPress website

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

2. Real-Time Radius Search (Custom Development)

Filter vendors/products within configurable radius (e.g., 5km, 10km)

Sort products by nearest vendor

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

WhatsApp Business API or Twilio

Template-based message sending

Triggered on reservation creation
