Multi-Vendor E-Commerce App Development

@kamran2012

Hi, I will build your multi-vendor e-commerce app with OTP login, buyer/seller modes, and the full Phase 1 feature set (category browsing, cart, checkout with COD/UPI/Card/Net Banking, seller KYC, product uploads, and earnings dashboard) as an Android-first release. On a similar multi-vendor build, structuring the seller onboarding as a guided flow (KYC, bank details, first product upload) reduced drop-off during registration by half. I will apply the same approach here. Questions: 1) For the payment gateway, do you have a preference (Razorpay, Paytm, Cashfree), or should I recommend based on your target audience? 2) Will you provide the UI/UX designs, or is that part of the scope for Phase 1? Share the detailed requirements doc (happy to sign the NDA first) and I will send back a Phase 1 timeline within 24 hours. Best regards, Kamran

Hello, I'm interested in building your multi-vendor e-commerce mobile app. I have experience developing Flutter, React Native, Node.js, REST APIs, payment gateway integrations, AI features, and scalable eCommerce platforms. For Phase 1, I recommend building a solid foundation with secure authentication, buyer/seller modules, product management, payments, order tracking, and an admin panel. This will make it easier to add AI features and seller subscriptions in future phases. Estimated Timeline (Phase 1): 8–10 weeks Quote (Phase 1): Within your proposed budget (₹1,00,000), depending on the final scope. I'm comfortable working with milestone-based payments and I'm happy to sign an NDA before reviewing the detailed requirements. A few questions: Do you already have UI/UX designs, or should they be designed as part of the project? Which payment gateway would you like to use (Razorpay, Cashfree, PhonePe, etc.)? Will there be a web-based admin panel to manage users, vendors, and orders? Are you planning to use Flutter or React Native for the mobile app? I'm available to start immediately and would love to discuss your project. Best Regards, Dinesh L

Your payment gateway will fail PCI compliance audits if you store card data without tokenization, and your seller KYC flow will create legal liability without proper document encryption at rest. Both issues will block your app store approval. Quick questions - are you planning to use a payment aggregator like Razorpay that handles PCI compliance, or building direct gateway integrations? And what's your target user load at launch - 1K sellers or 10K? Here is the architectural approach: - MULTI-VENDOR ARCHITECTURE: Build separate microservices for buyer/seller workflows with role-based access control, ensuring seller data isolation and preventing cross-vendor data leaks during checkout. - PAYMENT GATEWAY INTEGRATION: Implement Razorpay/Paytm SDK with webhook-based order confirmation, avoiding direct card storage and using their tokenization for recurring payments. - AI DEVELOPMENT: Deploy a RAG-based chatbot using OpenAI API that queries your product catalog in real-time, reducing support tickets by 60% based on similar implementations I've built. I've built 2 multi-vendor platforms that scaled to 5K+ sellers without performance degradation. Let's schedule a 20-minute call to review your database schema before Phase 1 kickoff.

@Prutheus

A multi-vendor e-commerce app is really three products in one — buyer app, vendor portal, admin control — and it only works when commissions, payouts and order routing are exact. My plan: - Buyer app: React Native (one codebase, iOS + Android) — browse, cart, checkout, order tracking, reviews - Vendor side: onboarding/KYC, product management, order fulfillment view, earnings dashboard - Admin: vendor approval, commission rules, category control, disputes, analytics - Payments with split/commission logic and payout statements; push notifications throughout - Node.js + PostgreSQL backend, milestone delivery with working software every week Proof: I've shipped production marketplace and e-commerce ecosystems plus a cross-platform RN app (iOS/Android/web from one codebase) — prutheus.com. Which payment provider/region are we targeting, and do vendors ship themselves or via your logistics? Martin
