Multi-Vendor Magento
PWA Marketplace
with Laravel Vendor
Platform
& Custom GraphQL
A unified commerce ecosystem where Magento powers the storefront and order management, Laravel powers the vendor management system, and GraphQL connects web, mobile apps, and vendor operations — enabling real-time synchronization across the entire marketplace.
Overview
Wezzomart operates as a multi-vendor marketplace where independent sellers manage products, inventory, and orders through a dedicated vendor system. The platform is built on a hybrid architecture combining Magento and Laravel.
Magento serves as the core commerce engine responsible for:
- Product catalog management
- Checkout and order processing
- Customer storefront experience
Alongside Magento, a custom Laravel-based vendor management platform was developed with a Vue.js frontend to allow vendors to manage their operations independently.
The full ecosystem includes:
- Magento PWA storefront for customers
- Laravel vendor management system with Vue.js dashboard
- Mobile application powered by Magento GraphQL APIs
- MinIO object storage for centralized media assets
GraphQL acts as the communication layer connecting all systems, enabling real-time synchronization of product data, orders, inventory, and vendor information. This architecture allows vendors to operate independently while customers experience a unified marketplace across web and mobile platforms.
The Challenge
Magento's default GraphQL implementation was not sufficient to support the complex requirements of a multi-vendor marketplace with mobile commerce and external vendor systems.
Limited GraphQL Infrastructure
Magento's out-of-the-box GraphQL layer lacked the endpoints required for a multi-vendor mobile platform:
- No structured vendor data access via GraphQL
- No wallet balance or transaction endpoints
- Insufficient social authentication support
- No vendor-specific order visibility layer
Multi-System Synchronization
Managing inventory, orders, and media across disconnected systems created critical operational risks:
- Inventory mismatches between Magento and vendor panel
- No real-time order visibility for vendors
- Duplicated media assets across platforms
- No automated status synchronization
- Incomplete products appearing in mobile app
Without these enhancements, the platform would face data inconsistencies, poor mobile experiences, and operational inefficiencies across vendors, customers, and administrators.
Our Solution
A modular architecture was implemented with Magento acting as the central commerce engine while GraphQL served as the communication layer between all systems.
Magento Commerce Layer
Magento was extended with custom GraphQL modules that exposed secure endpoints for mobile applications and vendor integrations. These endpoints enabled structured queries and mutations for:
Outcome: Both the mobile application and vendor panel interact with Magento in a consistent, structured, and secure way through a single GraphQL layer.
Vendor Management System
A dedicated vendor management platform was developed using Laravel with a Vue.js frontend, allowing vendors to manage their products, inventory, and incoming orders independently from the Magento admin interface.
- Vendors upload and manage products, pricing, and inventory directly within their own panel
- Incoming orders from Magento are automatically visible in the vendor dashboard
- Email notifications alert vendors of new orders instantly
- MinIO object storage provides centralized media management — both Magento and the vendor panel reference the same product images, eliminating duplication
Outcome: Centralized media storage reduces duplication and improves scalability as the marketplace grows and more vendors are onboarded.
Product Filtering Logic
To maintain consistency across platforms, custom filtering rules were implemented within the GraphQL layer to ensure only valid and purchasable products appear in the mobile application:
Simple products without custom options are automatically excluded from mobile API responses
Configurable products are filtered out when none of their child products contain valid customization options
Only complete, purchasable products are returned in mobile GraphQL queries
Outcome: Customers only encounter valid, purchasable products in the mobile application, maintaining a consistent and reliable shopping experience.
Real-Time Inventory Validation
Since vendors manage their own inventory within the vendor panel, inventory mismatches between Magento and the vendor system were a potential risk. A real-time validation mechanism was implemented with two validation checkpoints:
Add to cart: A lightweight verification request is sent to the vendor panel to confirm current inventory availability before the item is added
Checkout: A second verification occurs before order placement, ensuring final stock confirmation before the transaction completes
Outcome: Accurate stock validation is maintained without constant background synchronization that could overload the server infrastructure.
Order Synchronization
Order data flows seamlessly between Magento and the vendor system through an automated synchronization pipeline:
Order is placed by customer — order data is immediately transmitted to the vendor panel
Vendor receives an email notification and the order appears in their dashboard for fulfillment
Order status updates in Magento are automatically synced back to the vendor panel and reflected in customer notifications
Outcome: Vendors receive orders instantly while customers stay updated throughout the entire order lifecycle, with no manual intervention required.
Wallet Payment System
A custom wallet payment system was implemented to provide flexible checkout options. Customers can:
- Pay fully using their wallet balance for a faster, frictionless checkout
- Combine wallet balance with an external payment gateway when funds are insufficient
- Wallet balances are automatically adjusted once the order is completed, ensuring accurate financial reconciliation
Outcome: Flexible payment options improve the overall checkout experience and reduce cart abandonment caused by payment friction.
Social Authentication, Push Notifications & Performance
GraphQL-based social login was integrated to simplify account creation and login for mobile users, supporting Facebook and Google OAuth.
Push notifications were integrated to keep customers and vendors informed of key events including order placement, order status updates, and vendor-related activities.
System Architecture
The Wezzomart platform operates using a distributed architecture connecting multiple systems in a synchronized ecosystem.
Magento Commerce Engine
Core platform responsible for product catalog management, checkout processes, order lifecycle management, and extended GraphQL API endpoints for all integrations.

A multi-vendor marketplace is an e-commerce platform where multiple sellers can list and sell their products through a shared storefront while managing their own inventory and orders through dedicated vendor dashboards.
The marketplace operator manages the customer experience, checkout flow, and platform infrastructure while vendors focus on their own products and fulfillment.
GraphQL allows applications such as mobile apps and third-party systems to request only the data they need through structured queries, making integrations faster and more efficient compared to traditional REST APIs.
For Magento specifically, custom GraphQL modules allow the platform to expose vendor data, wallet balances, social authentication, and order management through a unified, secure API layer that scales with your business.
A vendor panel allows sellers to manage their products, inventory, pricing, and orders independently while the marketplace platform handles the customer-facing storefront and checkout flow.
In Wezzomart's case, the Laravel and Vue.js vendor panel integrates directly with Magento through custom APIs, allowing vendors to add products, monitor stock levels, receive new orders, and update fulfillment status — all without accessing the Magento admin interface.
Real-time inventory validation prevents overselling by ensuring that product availability is confirmed before an order is placed. This is critical when inventory is managed across multiple systems — as is the case when vendors control their own stock within a separate panel.
Without validation checkpoints at cart and checkout stages, customers could successfully place orders for out-of-stock items, leading to cancellations, refunds, and a poor customer experience.
Yes. Magento's headless architecture and extended GraphQL layer make it well-suited for powering multiple frontends from a single backend. The PWA storefront and mobile application both connect to the same Magento instance through GraphQL APIs, ensuring consistent product data, pricing, and order management across all channels.
Custom GraphQL modules extend this capability further by exposing vendor-specific data and marketplace features that are not available in Magento's default configuration.
