I want a unified system that lets wholesale and manufacturing vendors display their products while customers browse them through a smooth Flutter mobile app. There is zero commerce flow here—no add-to-cart, checkout, payment gateway, or stock management—just a clean catalogue experience segmented by industry. What I need built • Admin Panel – approve / reject vendor or customer registrations, manage industry tags, and control all listings. • Vendor Panel – industry-specific login, profile setup, product upload (single or multiple industries per item), and document submission for verification. • Customer App (Flutter) – industry-based login then searchable catalogue with instant filters by product name, salt name, vendor, and city. Verification flow Every vendor and customer must pass manual approval. During sign-up they will upload a business license, government ID, full contact details, PAN card, and supporting images; access is granted only after I clear them in the admin panel. Essential behaviour • Products are visible only after both the vendor and the listing itself are approved. • Customers see different industries according to their chosen profile. • Responsive web UI for admin and vendors, plus Android & iOS builds from the Flutter codebase. • Search and filter must remain fast even as the catalogue grows. Deliverables are production-ready source code, a brief hand-over document, and deployment support to my hosting and the app stores. If you are comfortable designing a lightweight REST API and securing the verification workflow, let’s talk timelines and milestones.
