Hi, This is Elias from Miami. I checked the details and understand you want to build a mobile-first B2B marketplace where suppliers and buyers can browse products, send RFQs, negotiate, message, pay, rate each other, and complete deals securely on iOS and Android. The real challenge here is designing the marketplace workflow clearly from the start. Supplier catalogs, buyer RFQs, messaging, payments, ratings, and order status all need to connect around one clean transaction flow. I've worked on mobile apps involving two-sided marketplace logic, user roles, messaging, payments, product catalogs, dashboards, and store deployment. I’d likely recommend Flutter or React Native for a faster simultaneous iOS/Android MVP, with a scalable backend using Node.js/NestJS or Firebase/Supabase depending on how complex the RFQ and payment workflow needs to be. I have a few questions to get a better understanding: Q1 – Should suppliers be able to list products themselves from the app? Q2 – Will payments happen inside the app from day one, or should MVP focus on RFQ and negotiation first? Q3 – Do you need an admin dashboard for user approval, disputes, and marketplace management? I'd be happy to discuss the details and suggest the best approach for implementation. Looking forward to hearing from you.

I can help with this, I will refine your wireframes, architect the backend, and build the full MVP — catalog, RFQ workflow, messaging, payments, and ratings — using Flutter for a single codebase across iOS and Android, then handle both store submissions. For the RFQ flow, I will implement real-time negotiation threads tied to each product listing with status tracking (pending, countered, accepted) so both buyers and suppliers see a clear deal pipeline — this keeps transactions structured and reduces drop-off during negotiation. Questions: 1) Do you have a backend preference, or should I propose a stack — Firebase, Node.js, or something else? 2) Will payments be escrow-based or direct between buyer and supplier? Ready to start whenever you are. Kamran

Hi, Your B2B marketplace project aligns closely with my experience building scalable mobile applications and multi-user platforms. I can take ownership from refining user flows and defining the technical architecture through MVP development, testing, and successful App Store and Google Play submissions. For this type of application, I recommend Flutter for a single, maintainable codebase that delivers a native experience on both iOS and Android while reducing development time and cost. On the backend, I'm comfortable with Node.js, Django, or integrating with an existing headless architecture, depending on your long-term goals. I can deliver key marketplace features including: • Buyer and supplier onboarding • Product catalogues and advanced search • RFQ and negotiation workflows • Real-time messaging • Secure payment integration • Ratings and reviews • Push notifications and analytics • Admin-ready, scalable architecture I have experience building production-ready applications with clean architecture, modular components, API integrations, and deployment pipelines. I prioritize well-documented code, transparent communication, and milestone-based delivery. Based on the outlined scope, I estimate 10–14 weeks for a working MVP, depending on final requirements and backend readiness. I'd be happy to review your wireframes and discuss the best approach to bring this marketplace to market successfully. Best Regards, Jemin Sagar

Hi I can build your B2B marketplace mobile app for both iOS and Android, covering supplier listings, buyer search, RFQ workflows, negotiation, messaging, payments, ratings, and store submission. The main technical challenge is keeping the two-sided marketplace flow simple on mobile while securely managing product data, RFQs, chat, deal status, payments, and user roles. I would recommend Flutter or React Native for a shared codebase, with a scalable backend using Node.js/NestJS or FastAPI, PostgreSQL, secure APIs, push notifications, and role-based access. I can start by refining your wireframes and user flows, then define the architecture, data model, API structure, and MVP modules before development. The supplier side can include profile management, catalogue uploads, product editing, RFQ responses, deal tracking, and ratings. The buyer side can include product discovery, advanced search, RFQ submission, negotiation, secure checkout, messaging, and order/deal history. I can also prepare clean documentation, modular code, testing builds, App Store and Google Play submission support, and share relevant marketplace examples directly in chat. Thanks, Hercules

Hi, A B2B marketplace succeeds or fails based on workflow efficiency, not just UI. I can help build a scalable Flutter-based iOS & Android app with supplier/buyer accounts, product listings, RFQ workflows, messaging, payments, and ratings. ✔ Flutter + scalable backend architecture ✔ Clean, modular, well-documented code ✔ MVP to App Store & Google Play deployment ✔ Experience with marketplace and business applications Quick question: Do you need an admin dashboard for managing users, listings, disputes, and transactions? I'd be happy to review the wireframes and provide an MVP roadmap and timeline.

@flapjakc

Bonjour! Une marketplace B2B en France — fournisseurs et acheteurs, catalogue produits, recherche, workflow RFQ, messagerie, paiements et évaluations sur iOS et Android simultanément. Les wireframes sont prêts, la logique métier est définie — on peut aller directement au build. React Native pour iOS et Android depuis une seule codebase, Node.js backend, PostgreSQL. Catalogue produits avec recherche et filtres, workflow RFQ complet (demande → offre → négociation → accord), messagerie in-app entre acheteurs et fournisseurs, paiements sécurisés via Stripe, système d'évaluations bilatérales. Architecture modulaire et code documenté pour faciliter les évolutions futures. Soumission App Store et Google Play incluse. J'ai lu le cahier des charges — le scope est clair et réalisable dans ce budget. Envoie-moi un message et construisons cette marketplace ensemble. Mateo

@abhishek060

Hi, A successful B2B marketplace is won or lost on the user experience—buyers need to find products quickly, suppliers need to manage inquiries efficiently, and both sides need a secure way to communicate and close deals. I like that you've already defined the business logic, user flows, and wireframes. That gives us a strong foundation to focus on refining the UX, designing a scalable architecture, and accelerating the MVP development process. For the MVP, I would recommend Flutter to launch on both iOS and Android simultaneously while maintaining a single, high-performance codebase. The application will be built with modular components and support key features such as product catalogs, advanced search, RFQ workflows, supplier-buyer messaging, payments, ratings, and future feature expansion. My approach is to deliver clean, well-documented code with transparent communication throughout the project. I've worked on marketplace-style applications involving multiple user roles, real-time interactions, and end-to-end deployment to both the App Store and Google Play. A couple of questions: • How detailed is the RFQ workflow currently defined in the wireframes? • Do you already have a preferred backend/payment provider, or are you open to recommendations? Based on the scope described, I estimate an MVP timeline of approximately 8–12 weeks. I'd be happy to review the wireframes and share my proposed architecture and development roadmap. Best regards, Abhishek

@vladang

Read through the Flottio cahier — the build really hinges on two things: Stripe Connect and the pro side being genuinely real-time. I'd start there. One NestJS backend (the spec already leans that way) feeding two React Native apps that share logic and ship to both stores together. The pro app comes first, since that's where timing matters: the 2-hour accept window, a push when a mission lands, and "mark as done" triggering the payout all have to survive patchy mobile data — so I'd queue those actions and confirm server-side rather than trust the device. The geographic matching (radius + availability + prestation) belongs in Postgres to stay under your 1s target. One subtle thing: I'd run the "no response in 2h → reoffer to the next pro" as a backend scheduled job, so it never depends on an app being open. Are you keeping the web dashboard for the entreprises, or should buyers go mobile too? And Express or Custom Connect accounts for the pros? Can start on the architecture this week.

@HamparProd

Hi, I can help build your mobile-first B2B marketplace app for both iOS and Android, from flow refinement through development, testing, and App Store / Google Play submission. For fast and maintainable delivery, I would recommend Flutter or React Native with a shared backend API. For the backend, I can use Node.js/NestJS, Firebase, or Supabase depending on how much custom marketplace logic you need. My preference for this type of app would be Flutter + Node.js/NestJS + PostgreSQL because it gives strong scalability for buyers, suppliers, RFQs, orders, messages, ratings, and future payment workflows. The MVP can include buyer/supplier registration, product listings, catalogue search, category filters, RFQ creation, supplier responses, in-app messaging, payment-ready deal flow, ratings/reviews, notifications, account dashboards, and admin-ready backend structure. I will keep the code modular, documented, and easy to extend after launch with advanced payments, subscriptions, logistics, bulk pricing, supplier verification, and analytics.
