A B2B marketplace connecting wholesale buyers and sellers through a seamless inquiry → quotation → order workflow — with catalog management and real-time chat.

Buyfyn is a B2B marketplace that digitises the entire wholesale buying and selling process. Buyers discover suppliers and raise inquiries, sellers respond with smart quotations, and once a buyer accepts — the order is confirmed automatically. No back-and-forth, no paperwork, no missed messages.
I built the Buyfyn mobile app from scratch in Flutter using BLoC for predictable, event-driven state management and Firebase for backend services, real-time chat and push notifications — delivering a consistent experience across iOS and Android from a single codebase.
Wholesale B2B trade still runs on phone calls, WhatsApp and manual paperwork. Buyers struggle to discover the right suppliers, quotations get lost, and there's no clear audit trail from inquiry to confirmed order. The goal was to build a structured, digital workflow that makes B2B sourcing as simple as placing a retail order.
The heart of Buyfyn is a structured three-step trade flow that eliminates ambiguity and keeps both parties aligned at every stage.
Buyer browses catalog and sends a structured inquiry to the seller
Seller responds with a smart quotation — pricing, quantities and terms
Buyer accepts — quotation auto-converts into a confirmed order instantly
Buyers browse verified suppliers and their full product catalogs in one place.
Structured inquiry flow so buyers clearly communicate requirements to sellers.
Sellers send detailed quotations that auto-convert to confirmed orders on buyer acceptance.
Sellers maintain a structured product catalog with pricing, variants and availability.
Built-in messaging so buyers and sellers can negotiate and clarify details without leaving the app.
Instant alerts for new inquiries, quotations received, and order confirmations.
Buyfyn is built in Flutter for a consistent, native-quality experience across iOS and Android from a single codebase. BLoC (Business Logic Component) drives a clean, event-driven state architecture — keeping UI, logic and data neatly separated and easy to scale. Firebase powers authentication, the real-time database, in-app chat and push notifications.
