Comprehensive Multi-Vendor Marketplace Development

@Microlent

A 3-application marketplace requires careful planning because the Customer App, Vendor App and Super Admin Panel must operate on one central backend with properly defined roles, inventory, orders, payments and commission workflows. I can help develop the complete marketplace ecosystem, including: • Customer Mobile App: product browsing, search, cart, orders, payments, tracking, wishlist, reviews and notifications • Vendor App: store management, products, inventory, orders, earnings and basic analytics • Super Admin Panel: vendor approval, users, products, categories, orders, commissions, coupons, banners, reports and permissions • Central Backend/API: authentication, business logic, order workflows and integrations Recommended stack: Flutter for both mobile applications, Node.js/NestJS for the backend, PostgreSQL for structured marketplace data, React.js for the Admin Panel, REST APIs, JWT/OTP authentication and Firebase Cloud Messaging. I would structure the project in phases: requirement finalisation, UI/UX, backend architecture, Customer App, Vendor App, Admin Panel, integrations, QA and deployment.

My proficiency with Flutter, Node.js, and MySQL guarantees a top-notch performance for your Customer App as well as your Vendor App — ensuring functionalities such as inventory management, order tracking, OTP/JWT-based authentication, push notifications, and much more work seamlessly. Apart from these two apps, your Super Admin Panel which acts as the backbone of your marketplace is in safe hands with me. Expertise in tech such as React.js and PostgreSQL that powers similar dashboards ensures that each aspect from product management to database handling is precisely executed.

You need three connected products that operate as one marketplace, with consistent inventory, orders, payments, commissions, notifications, and permissions across customers, vendors, and administrators. I have 9 years of full stack experience, including Flutter, Node.js, React, PostgreSQL, AWS, Stripe, and production e commerce systems at Poundit. I recommend Flutter for both mobile apps, React for the admin panel, NestJS with REST APIs for the backend, PostgreSQL for transactional consistency, Firebase Cloud Messaging for notifications, and AWS for deployment. The system will use modular services for authentication, catalogue, inventory, cart, orders, payments, commissions, reviews, support, analytics, and role based administration. Development will include responsive UI implementation, secure OTP and JWT authentication, API documentation, automated testing, deployment configuration, source code ownership, and warranty documentation.

@aprkdream

Hi, Building a complete three-app ecosystem for a building materials marketplace is a significant undertaking. I understand the complexity of managing customer, vendor, and admin workflows simultaneously, especially with the need for real-time inventory and order tracking. I have built several multi-vendor eCommerce platforms that handle similar logistics and payment flows. For instance, I recently developed a multi-vendor platform integrating Stripe, Razorpay, and PayPal, complete with vendor onboarding and complex order management. My background includes 11 years of experience with PHP/Laravel and Node.js, specifically focusing on high-traffic marketplaces and ERP systems like AERO, which required robust RBAC and multi-tenant architecture. For your project, I will use Laravel for the backend to ensure stability and scalability, paired with React Native or Flutter for the mobile applications to cover both iOS and Android efficiently. I’ll design the MySQL database schema to handle product catalogs, order states, and user data effectively. To ensure the quote is accurate for your needs: 1. Do you already have the UI/UX designs ready, or would you like me to include wireframing in the scope? 2. Are there specific third-party logistics (3PL) APIs you want integrated for delivery tracking, or will that be manual? Let's discuss how to structure the payment milestones to keep this project on track. Best Regards, Anil Prajapati
