Scalable B2B+B2C eCommerce App Development

@Microlent

Hi, I’ve gone through your B2B + B2C eCommerce requirements, and I can build a scalable, production-ready system with clean architecture designed for long-term growth. I’ll use Flutter for Android & iOS, Node.js (NestJS) for backend, PostgreSQL with Redis for performance, React.js for admin panel, and AWS for storage and deployment. The system will support both retail and wholesale flows within a single backend while keeping logic modular and easy to extend. Core modules will include customer & business accounts, OTP/email login, product catalog, cart & checkout, GST billing, quotations, bulk orders, inventory management, payments, orders, wishlist, reviews, and push notifications. We’ll design the system in phases: - Core platform (auth, products, cart, orders, pricing) - B2B features (wholesale pricing, GST, quotations) - Admin + inventory + reporting - Final testing, optimization, and deployment I focus heavily on performance, clean code, and maintainability so your platform can scale without rework later. I’ve built similar marketplace and eCommerce systems with multi-role pricing and admin-driven inventory flows, and can share relevant examples. Ready to start immediately once scope is confirmed.

Your dual-mode pricing model (B2B wholesale + B2C retail) will create database contention if you're running dynamic pricing calculations on every product query. At 10K+ SKUs with tiered pricing rules, this becomes a 2-3 second bottleneck that kills conversion. You'll need a Redis caching layer with intelligent invalidation tied to inventory updates, not just time-based expiry. Quick question - are your GST calculations region-specific (CGST/SGST splits), and do wholesale clients get credit terms that require approval workflows? This changes how we architect the checkout flow and payment reconciliation. Here's the architectural approach: - FLUTTER: Single codebase for Android/iOS with offline cart persistence and optimistic UI updates to handle flaky mobile networks during checkout. - NODE.JS + NESTJS: Microservices architecture separating catalog, orders, and payments so Black Friday traffic doesn't crash your entire platform when one service spikes. - POSTGRESQL: Partitioned tables for orders by month, JSONB columns for flexible product attributes, and materialized views for real-time inventory across warehouses. - REDIS: Session management, cart state, and a write-through cache for pricing matrices so B2B clients see instant quotes without hitting the database. - REACT ADMIN PANEL: Role-based dashboards with bulk import tools for catalog management and automated GST invoice generation compliant with Indian tax requirements. - AWS INFRASTRUCTURE: S3 for product images with CloudFront CDN, RDS for PostgreSQL with read replicas, and SQS queues for asynchronous order processing during peak loads. I've built 3 similar dual-mode platforms that scaled from 500 to 50K daily orders without performance degradation. Let's schedule a 20-minute technical call to align on your warehouse integration requirements and payment gateway selection before we finalize architecture.

I have read your job post and I am a Full Stack Developer with experience in Flutter, React.js, Node.js, PostgreSQL, AWS, and large-scale eCommerce application development. I have developed B2B and B2C platforms with user authentication, product catalogs, payment gateway integration, inventory management, order tracking, admin dashboards, and ERP integrations. For your project, I will build a scalable solution using Flutter, NestJS, PostgreSQL, Redis, React.js, and AWS following clean architecture and best development practices. The platform will support wholesale pricing, GST billing, quotations, bulk orders, push notifications, and future AI features such as product recommendations and smart search. I will provide clean, well-documented code, regular progress updates, post-launch support, and a scalable foundation for future growth. Do you already have UI/UX designs ready, or should they be designed as part of the project? Which payment gateway and ERP/CRM system do you plan to integrate?

@kishanbwts

I’ve helped build scalable B2B and B2C eCommerce platforms before, combining Flutter for mobile apps with Node.js backends to handle complex features like wholesale pricing, GST invoicing, and bulk order processing. To start, I’d design separate flows for business and customer accounts to keep experience smooth. Redis can manage session and cache for fast cart and inventory updates. For security, OTP/email authentication with token refresh will cover both user types reliably. Using NestJS on Node ensures a solid, maintainable API, while React will deliver a responsive admin panel tailored for inventory and order management. Does your payment gateway need multi-currency or custom tax logic support? Also, do you envision AI-driven features launching in the same timeline or as a phased upgrade? Based on similar projects, we can deliver a solid MVP—including product catalogs, order tracking, and quotations—in about 10 weeks, leaving room for testing and refinements. I’m ready to break this down into milestones and start building the core architecture immediately.

@techsty2014

Hi there, We will build your B2B + B2C eCommerce platform in Flutter with a NestJS backend, React admin panel, and PostgreSQL on AWS. For the dual account model, we will separate B2B and B2C pricing logic at the API layer. Wholesale pricing, GST invoicing, and bulk order quotations will run through dedicated services so retail checkout stays fast and unaffected. Redis will handle session caching and inventory locks during high traffic. A couple of quick things to confirm: 1) Which payment gateway do you prefer (Razorpay, Stripe, or another)? 2) Do you have an existing ERP or accounting system the platform needs to sync with? The number quoted here is a starting estimate. The exact cost and timeline will be confirmed after we go through the full scope together. Looking forward to your response. Best regards, Faizan
