Store Inventory Software With Live Updates

I need a straightforward inventory-management application that keeps my stock levels accurate the moment an item is received or sold. The single, non-negotiable feature is real-time stock updates; every change must be reflected instantly in the dashboard so I can make decisions without refreshing pages or exporting reports. I run a small retail store, so the interface should stay clean and intuitive—think quick look-ups, simple filters, and a clear alert whenever any SKU hits a low-stock threshold. If you already have experience connecting inventory logic to barcode scanners or automated reordering modules, let me know; those extras aren’t mandatory right now but I may expand into them later and would prefer a codebase that can grow without a rewrite. Core deliverable • A runnable application (web or desktop) that tracks products, quantities, suppliers, and movements, updating counts in real time. Acceptance criteria • Add, edit, or remove an item and immediately see the new total reflected across every view. • Simultaneous access by two users must never create conflicting numbers. • A simple export (CSV or XLSX) of current stock should match the on-screen totals to the unit. Please outline the tech stack you intend to use, any existing libraries you’ll leverage, and an estimated timeline. I’m ready to start as soon as I find the right fit.
