Need a Custom B2B E-commerce Android App (Flutter) for Mobile Accessories Wholesale Description: I am looking for an experienced Flutter developer from India to build a custom B2B/Wholesale mobile app for my mobile accessories business. Key Requirements: 1. Restricted Access / Invite-Only: No public catalog. Retailers must register with their Mobile Number (OTP) and shop details. They cannot see any products or prices until I manually "Approve" them from the Admin Panel. 2. Wholesale Features: Minimum Order Quantity (MOQ) logic for each item (e.g., box packing of 10x, 50x pieces). 3. Payment System: Integrated Payment Gateway (Razorpay/Cashfree) for online payments (UPI, Cards) along with a "Pay via Transport/Offline" option for cash clients. 4. Simple Admin Dashboard: A web panel or mobile app for me to upload products, update stock, and approve new customers. Technology Preferred: Flutter (so we can launch on iOS in the future using the same code). Payment Terms: This will be a strict Milestone-based contract via Escrow. No upfront advance outside the platform. Source code handover is mandatory. Firebase ya supabase

Hi, CnEL India can build this B2B wholesale mobile commerce app using React Native, providing a shared codebase for Android and future iOS expansion. Our methodology: * Define retailer registration, approval, product visibility and wholesale ordering workflows. * Build OTP-based registration with shop/business details. * Implement admin-controlled approval so unapproved retailers cannot access products or prices. * Create product catalogue, stock management, MOQ/box-packing rules and wholesale pricing. * Integrate Razorpay/Cashfree for UPI and card payments. * Add a secure offline/transport payment option for approved cash customers. * Build a simple admin web panel for customer approval, products, stock and orders. * Use Firebase or Supabase based on the final data, authentication and notification requirements. * Implement secure role-based access and backend validation. * Optimize the mobile experience for different Android devices and future iOS deployment. * Test OTP, approval states, MOQ calculations, pricing, inventory, payments and order flows. * Deliver complete source code, setup documentation and deployment guidance. * Work through the requested milestone-based Escrow process. If React Native is acceptable instead of Flutter, we can start with the database structure and approval/order workflow, then develop the app module by module.

Hi, I am a Flutter developer from Gujarat and can build your B2B mobile accessories app. Retailers register with mobile OTP and shop details, and see no products or prices until you approve them from the admin panel. Each product will have MOQ and box packing rules (10x, 50x) enforced in the cart. Payments via Razorpay or Cashfree for UPI and cards, plus a Pay via Transport/Offline option for cash clients. A Laravel web admin lets you upload products, update stock, approve customers and track orders. Built in Flutter so iOS can launch later from the same code. Do you need tier-wise pricing per retailer? Regards, Harsh Thoriya

Hi, I can build your invite-only B2B wholesale mobile accessories app in Flutter with a scalable architecture for future iOS launch. I’ll implement mobile OTP registration, shop details, and admin approval so products and pricing remain hidden until a retailer is approved. The app will support product-wise MOQ and box-packing logic, along with stock and wholesale pricing management. For payments, I can integrate Razorpay/Cashfree with UPI, cards, and a “Pay via Transport/Offline” option for cash customers. I’ll build a simple admin dashboard for customer approvals, product uploads, pricing, inventory, and order management. Development will follow milestone-based delivery with complete source-code handover and clean, maintainable Flutter code. Best, Rahul

Hi, this B2B app needs more than a standard e-commerce flow—the important part is controlling who can access the catalog, enforcing MOQ/box quantities, and keeping wholesale ordering simple. I can build this in Flutter with Firebase, using OTP authentication, an approval-based customer workflow, Firestore for products/orders/stock, Firebase Storage for product images, and FCM for order and approval notifications. Razorpay/Cashfree can handle online payments, while the offline transport-payment option can be included in the order flow. I can also build a simple web admin panel for customer approval, products, stock, MOQ and orders, with the architecture kept ready for a future iOS release. Would you like the admin panel as a web dashboard or Flutter Web?

Your goal is clear: a Flutter B2B wholesale app where retailers register with mobile OTP, get admin approval before seeing any catalog or prices, then order in MOQ box quantities and pay via Razorpay/Cashfree or offline. That is exactly the kind of e-commerce system I build. My approach: Flutter with Supabase for structured wholesale data and row-level pricing security — OTP login with shop KYC, admin approval gating the catalog, per-item MOQ logic, Razorpay/Cashfree UPI/cards integration plus an offline payment option, and an admin panel for products, stock and approvals. Milestone delivery with full source handover. For experience: I have built e-commerce and marketplace systems with merchant onboarding and payment flows, so approval-gated catalogs and wholesale pricing are familiar. Two quick questions: should unapproved retailers see a waiting screen or stay fully locked, and do you need per-retailer price lists or one wholesale price for all? I can start auth and approval this week and iterate by milestones.

Hi, The key here is making this a genuinely private wholesale platform—not just a catalog hidden behind a login. Retailers should see products and prices only after your approval, and MOQ/box quantities must be enforced by the backend so orders cannot bypass your wholesale rules. I’d use Flutter for the retailer app and Supabase for PostgreSQL, authentication, product images and secure data access, plus a simple web admin panel for approving retailers, managing products and updating stock. Razorpay or Cashfree would handle online payments, while transport/offline orders would follow a separate payment-status workflow. I’d split delivery into escrow milestones: authentication and approval, catalog/MOQ/cart, checkout and payment, admin panel, then testing and source-code handover. No advance outside the platform. One question: will all approved retailers have the same wholesale prices, or do you need customer-specific pricing? Regards Abhishek

For this wholesale accessories app, I’d enforce retailer approval at the API level, not just hide the catalogue in Flutter, so an unapproved account cannot access products or pricing through direct requests. MOQ and box quantities should also be server-validated to prevent invalid orders. My priorities would be admin workflows and maintainability. I recommend Flutter for the customer app, NestJS + PostgreSQL for the backend, Firebase OTP authentication, and a lightweight React admin panel. Razorpay/Cashfree can handle UPI/cards, while offline/transport payments can create orders with a clearly managed pending/payment-status workflow. I handle mobile products end to end, including APIs, authentication, payment integrations, admin systems, deployment and complete source-code handover. Milestone-based escrow and repository-based delivery are fine. A relevant project is MofiBasket, where we developed custom e-commerce functionality covering products, stock, purchasing/delivery tracking, coupons, promotions and multicurrency workflows. The Flutter codebase can also be structured for a later iOS launch without rebuilding the business logic.
