Multi-Vendor E-Commerce Website
Budget: $30 – $250 NZD
BZMarket - Advanced Multi-Vendor E-Commerce Ecosystem
1. Executive Summary
BZMarket is not just a simple online store; it is a comprehensive multi-vendor ecosystem (similar to Amazon or Etsy) tailored for the local market. The platform connects Buyers, Sellers, and Administrators through a seamless, secure, and gamified interface.
The primary challenges are data isolation (security between sellers), scalability, and user engagement (loyalty/social features).
2. Technical Stack (Mandatory)
Front-End: React.js / Next.js (Must use Server-Side Rendering - SSR for SEO).
Back-End/API: Node.js.
Database & Auth: Supabase (PostgreSQL).
Deployment: Vercel (recommended) or VPS.
3. Architecture & Security Strategy
The freelancer must implement a Role-Based Access Control (RBAC) system.
Database Isolation: Utilization of Supabase Row Level Security (RLS) is mandatory. A seller must never be able to query data belonging to another seller via the API.
Data Integrity: Implementation of "Soft Deletes" (archiving instead of deleting) for products and orders to maintain historical data.
Defined User Roles:
Guest: Browse, Search, Cart.
Customer: Buy, Review, Chat, Earn Points.
Vendor (Seller): Manage Shop, Products, Orders, Ads.
Moderator: Validate products, Resolve disputes.
God Admin (Super Admin): Full system control, Financial oversight, Staff management.
4. Detailed Feature Specifications
A. The Front-End (Customer Experience)
1. Dynamic Home Page:
Smart Feed: If the user is logged in, show "Recommended for You" based on view history. If new, show "Trending Now" (based on click-through rate).
Flash Sales: A dedicated section with a countdown timer for time-sensitive deals.
2. Advanced Search & Discovery:
Fuzzy Search: The system must handle typos (e.g., searching "Iphne" should find "iPhone").
Dynamic Filtering: Filters must change based on category (e.g., "Clothing" shows Size/Color; "Electronics" shows RAM/Storage).
3. Complex Cart & Checkout (Critical):
Split-Order Logic: If a customer buys Item A (from Vendor 1) and Item B (from Vendor 2), the system must generate one Parent Order ID for the customer, but split it into two Child Order IDs in the backend.
Payment Gateways: Integration of Cash on Delivery (COD) with phone number verification (OTP) to reduce fake orders.
B. The Vendor Dashboard (Business Center)
1. Product Management (CRUD):
Variants: Support for complex variations (Color, Size, Material) with independent stock counts for each variant.
Bulk Actions: Ability to edit stock or prices for multiple items at once.
2. Financial Wallet & Ledger:
Transaction Status: Money from sales should move through statuses: Pending (Order placed) -> Escrow (During delivery) -> Available (Delivered + X days return policy).
Withdrawal Request: Interface for vendors to request payouts.
3. Marketing Tools (Internal Ads):
Sponsoring System: Vendors can purchase "Ad Credits." They use these credits to bid for top placement in search results or category pages.
Coupons: Vendors can generate their own discount codes.
C. The "God Admin" & Moderator Dashboards
1. God Admin (Superuser):
Global Analytics: Real-time dashboard showing GMV (Gross Merchandise Value), Total Commission Earned, and Active Users.
Commission Settings: A simple input field to change the platform commission rate globaly (e.g., changing from 5% to 7%) without touching code.
Impersonation: Ability to "View as Vendor X" to troubleshoot issues.
2. Moderator Interface:
Approval Queue: New products uploaded by vendors go to a "Draft" state. Moderators must approve them before they go live (checking for prohibited items).
Dispute Center: A ticket system where Mods can mediate between a Buyer and a Seller regarding refunds or returns.
5. Engagement & Growth Systems (The "Extra Mile")
A. Gamification & Loyalty System
Points Engine:
Logic: Earn X points for every Y Currency spent.
Tiers: Bronze, Silver, Gold statuses based on yearly spend.
Rewards: A checkout slider allowing users to "Pay with Points" (conversion rate defined in Admin).
B. Referral System (Growth)
Mechanism: Unique referral links (e.g., bzmarket.com/ref/john).
Double-Sided Reward: The referrer gets a commission/points, and the referee gets a welcome discount.
Fraud Protection: Block referrals if the IP address or Device ID matches the referrer.
C. Social Commerce
Store Following: Users can "Follow" a vendor.
Notifications: Push notifications sent to followers when that vendor posts a new product.
Feed: A personalized social feed showing only products from followed shops.
D. Integrated Messaging System
Real-Time Chat: WebSocket integration for instant messaging between Buyer and Seller.
Smart Filters: Regex filters to detect and warn/block users trying to share phone numbers or external emails (to prevent taking the transaction off-platform).
6. Analytics & Intelligence
1. Vendor Analytics:
Conversion Funnel: Show vendors: "100 people saw this item, 10 clicked, 0 bought."
Revenue Charts: Visual graphs (Day/Week/Month).
2. Admin Intelligence:
Heatmaps: Which categories are performing best?
Search Logs: What are users searching for that returns zero results? (Helps identify market gaps).
7. Deliverables & Documentation
The freelancer is expected to provide:
Source Code: Clean, commented, and modular code hosted on GitHub/GitLab.
API Documentation: Swagger/OpenAPI documentation for all backend endpoints.
Deployment Guide: Step-by-step instructions to deploy the platform on a production server.
Database Schema: An Entity-Relationship Diagram (ERD) explaining the table structures.
