I need a complete mobile application that lets me publish and sell my own service-based inventory in the HVAC spare-parts market. At launch I will be the only seller, so I first need a clean way to upload, edit, and track every item I list. As adoption grows, the architecture must allow me to onboard additional sellers with their own catalogs without rebuilding anything. Buyer access will be invitation-only. That means secure, code-based sign-up flows and an admin console where I can issue, revoke, or monitor invitations at any time. I’m still deciding whether in-app appointment scheduling is necessary, so please structure the back-end in a way that lets us plug that module in later without major refactoring. Deliverables • iOS and Android apps (or a single cross-platform build) connected to a scalable back-end • Admin panel for inventory, invitation management, and multi-seller control • Database seeded with my full HVAC parts catalog, ready for immediate launch Code needs to be clean, documented, and deployed to stores or a test environment I can access.

I can build a scalable mobile application for your HVAC spare-parts service inventory, designed to work smoothly at launch with a single seller and expand later to multiple sellers without rework. I recommend a cross-platform mobile app (Flutter) for iOS and Android, backed by a modular, API-driven backend. You’ll have full control to add, edit, track, and manage inventory, with pricing, availability, and basic analytics. The database and permissions will be structured seller-wise from day one, so onboarding new sellers later is seamless. Buyer access will be invitation-only, implemented through secure, code-based sign-ups. An admin panel will allow you to generate, revoke, track, and monitor invitations in real time, along with inventory and seller controls. The backend will be designed in a plug-and-play manner, allowing future modules—such as appointment scheduling—to be added without major refactoring. Clean separation of services ensures long-term flexibility. Deliverables include iOS & Android apps, a web-based admin panel, a scalable backend, and your HVAC parts catalog fully seeded and ready for launch. Code will be clean, documented, and deployed either to app stores or a test environment you can access immediately. I focus on clarity, scalability, and maintainable architecture so the product can grow as adoption increases.
