I need a custom stock-inventory system that I can run for life without any recurring subscription fees. The application must work on both Windows PCs and Android phones and let me manage an unlimited number of items entirely through voice commands. Core workflow I want: • Speak to add a new item, update its quantity, or ask the system to generate reports. • See changes reflected instantly across PC and phone thanks to real-time syncing. • Scan barcodes with the phone camera or a USB scanner on the PC to speed up data entry. • View clear analytics—stock on hand, fast-moving items, out-of-stock alerts—through an easy dashboard. Key acceptance criteria 1. Windows desktop app (offline-first, with optional cloud sync for the phone). 2. Android app or PWA that mirrors all desktop functions. 3. Reliable voice recognition in English for the three commands above, with the option to expand later. 4. Unlimited SKUs without performance slow-downs. 5. One-time licence build. I do not want a SaaS product or any per-user limits. 6. Source code, installable executables/APKs, and brief user documentation delivered at hand-off. I’m open to the tech stack—Python, .NET, Flutter, React Native, or anything you can justify—as long as it meets the criteria above and remains maintainable. If this sounds like a fit, tell me how you’ll approach the voice layer, barcode integration, and cross-platform sync, plus a rough delivery timeline.

I have also developed Shopify-based solutions and inventory integrations. I can build your system as a one-time licensed application with no recurring subscription or per-user fees. My approach: Windows:Offline-first desktop app with local database and optional cloud sync. Android: Android app/PWA that mirrors the desktop functionality. Voice: English voice commands for adding items, updating quantities, and generating reports, with an architecture that allows more commands later. Barcode: Phone camera scanning and USB barcode scanner support on Windows. Sync: Real-time cloud synchronization between devices, while Windows continues working offline. Dashboard: Stock levels, fast-moving products, low/out-of-stock alerts, and analytics. Scalability: Designed to handle a large number of SKUs without unnecessary performance limitations.

Hi — this is squarely my kind of build. The most important line in your brief is "run for life without subscription", and it quietly rules out the obvious approach: Google/Azure speech APIs bill per request, so a voice app built on them IS a subscription in disguise. I'd build the voice layer fully offline. • VOICE — on-device recognition with Vosk (offline, zero per-use cost) for your three commands (add item, update quantity, generate report), using a small grammar so it stays accurate in a noisy stockroom; the vocabulary expands easily later. • BARCODE — phone-camera scanning via the native scanner API; on Windows a USB scanner already acts as a keyboard, so it drops straight into the item field. • SYNC — one Flutter codebase compiles to BOTH Windows desktop and Android, so the phone truly mirrors the PC. Local SQLite is offline-first; changes sync through a light layer when online. You get full source, a Windows .exe + Android APK, and short docs — one-time licence, no SaaS, no per-user limits, unlimited SKUs. ₹12,500 is Phase 1: the Windows + Android app with offline voice for the three commands, barcode entry, local DB and the stock/out-of-stock dashboard. Phase 2 adds cloud sync and expanded voice/analytics. Phase 1 timeline ~2.5 weeks. Happy to demo Vosk on a call. — Aakaash

Hello, Your requirement is clear: a one-time inventory application that works across Windows and Android, supports voice-driven stock management, barcode scanning, real-time synchronization, and remains usable without recurring SaaS fees. I’d approach this with Flutter for the Android/PWA experience and a Windows-compatible application layer, backed by a local-first database with optional cloud synchronization. ✓ Voice commands for add, update quantity and report generation ✓ Offline-first inventory management on Windows ✓ Android app with camera barcode scanning ✓ USB barcode scanner support on PC ✓ Real-time sync when connectivity is available ✓ Stock, fast-moving items and out-of-stock analytics ✓ Scalable SKU/data structure without artificial limits ✓ One-time build with complete source code and installers The voice layer would convert spoken commands into structured inventory actions, with validation before updating stock. Sync would use conflict-safe data handling so changes remain consistent between devices. Please confirm whether cloud sync should be optional or always enabled when internet is available, and whether you already have a preferred speech-recognition provider.

Hi, I can build this as a **one-time-license, subscription-free inventory system** with complete source code and no per-user/SKU limitations. I recommend **Flutter for Android + Windows**, with a local-first database such as SQLite and an optional self-hosted/cloud sync layer for real-time updates. For the voice layer, I’ll implement reliable English speech recognition with command parsing for adding items, updating quantities, and generating reports, while keeping the architecture expandable for future commands. Barcode scanning will support both the Android camera and USB scanners on Windows. The dashboard will provide stock levels, fast-moving products, low/out-of-stock alerts, search, filters, and analytics. Offline operation will be supported on Windows, with changes synchronized when connectivity is available. You’ll receive the complete source code, Windows installer, Android APK, documentation, and deployment/setup guidance.

I'll build this as a standalone, perpetual-license system using C# WPF for Windows (with SQLite for offline-first storage) and Flutter for Android to share UI logic and minimize maintenance. Voice recognition will use the Windows Speech Recognition API on desktop and Google's Speech-to-Text on Android for reliable English command parsing (add item, update quantity, generate reports). Barcode scanning integrates USB scanner input on Windows and camera-based scanning via the barcode_flutter package on Android. Real-time sync uses a lightweight local-first approach with optional cloud backup via encrypted SQLite replication. The dashboard shows stock levels, velocity metrics, and out-of-stock alerts with charts built on Flutter's fl_chart. I'll deliver the complete source code, both executables, APK, and user docs covering setup, voice commands, and offline workflows. This keeps you in full control with zero ongoing fees.
