Windows Inventory & Sales System

@muhammadali33345

Build a native Windows 10/11 inventory & sales app using an offline-friendly stack: .NET (C#) + SQLite (single file) with a clear local backup/restore flow. Each USB barcode scan on either counter will post the sale instantly, then atomically decrement stock for the same SKU to prevent conflicts. Core screens: 1) Simple single-role login. 2) Dashboard: today’s total sales value, per-item remaining stock, and a highlighted low-stock alert list. 3) Daily export: Excel + PDF with sales, current inventory, and a small trend chart (best sellers) for quick review. Delivery includes: installer + complete source, a live test setup proving both scanners update the same inventory safely, and a short user guide (install, daily use, backup/restore). I’ll also include a Can you confirm the barcode type/format (EAN-13/Code128) and how SKUs are matched to scanned codes for exact inventory sync? insertion point in the dashboard workflow notes. Milestones: - Prototype (login, scan-to-sale flow, dashboard): 6 days - Live-counter test (two scanners, conflict-proof sync, alerts): 8 days - Final polish (exports, charts, installer, guide): 4 days

I can develop a native Windows inventory and POS synchronization system with real-time stock updates across both counters, barcode scanner integration, low-stock alerts, offline support, reporting (PDF/Excel with charts), and an easy backup/restore process. I’d recommend C# (.NET) with SQLite/SQL Server Express for stability, fast deployment, and seamless Windows performance.

Hi, I can build your Windows inventory + POS sync system with real-time stock updates across both USB barcode scanners using a robust offline-first architecture (C# .NET WPF or WinForms with SQLite/SQL Server Express). The system will ensure instant scan-to-sale processing, synchronized inventory deduction, and real-time low-stock alerts. I’ll design a clean dashboard showing daily sales, stock levels, and alerts at a glance, along with exportable PDF/Excel reports and simple trend charts. I’ve built similar desktop POS and inventory systems where concurrency and real-time updates were critical, so I’ll ensure both counters always stay perfectly in sync without conflicts. I’ll also provide installer, full source code, and a clear backup/restore mechanism. Ready to start immediately and can share milestones (prototype → live scanner test → final polish) with realistic timelines.

Hi! I can build this inventory and sales system in Python, using SQLite for the local database (with easy backup/restore via file copy) and a clean desktop GUI (PyQt or Tkinter) for the dashboard. Plan: - Barcode scanners work as standard HID keyboard input, so both checkout counters can post sales instantly into the same SQLite database with proper locking to avoid conflicts between the two counters. - Real-time stock deduction on each scan, with a configurable low-stock threshold that triggers an alert section on the dashboard. - Dashboard shows today's total sales, live stock levels, and alerts at a glance. - End-of-day report generation (PDF via reportlab, Excel via openpyxl) with sales summary, inventory snapshot, and a simple trend chart (matplotlib). - Simple single-role login with basic credential check, no complex permission layers. - Packaged as a Windows installer so it runs offline on Windows 10/11. Milestones I'd suggest: 1. Prototype: database schema, login screen, basic dashboard (3-4 days) 2. Live-counter test: dual barcode scanner sync, stock alerts (3 days) 3. Final polish: reports, trend chart, installer, user guide (2-3 days) I'll deliver full source code, the installer, a sample report/chart, and a short user guide. Happy to do a live test with both scanners before final delivery. Let me know if you'd prefer PyQt over Tkinter for the UI and I'll confirm the milestone schedule.

@RamiGamalMahmoud

Hello, Your project is very close to systems I have developed and delivered previously. I have built multiple sales, inventory, and warehouse management applications for desktop environments, including solutions that handle stock movements, real-time inventory updates, barcode-based workflows, reporting, user authentication, and multi-user operation. The dashboard would provide a clear operational overview, including today's sales performance, current inventory levels, and highlighted low-stock notifications, while daily reports could be exported to PDF or Excel with sales summaries, inventory status, and trend charts that help identify top-selling products. My preferred stack would be: • C# / .NET 8 • WPF (MVVM Architecture) • SQL Server Express or SQLite, depending on your deployment preference • LiveCharts for dashboards and trend analysis • Professional Windows Installer • Automated backup and restore tools The final delivery will include the complete source code, installer package, sample reports, user documentation, and testing to verify that both checkout stations update the same inventory data without conflicts. I would be happy to discuss the expected transaction volume, network setup between the counters, and barcode scanner models to provide an accurate timeline and implementation plan.

@graterle1990

Hi, I have worked on a similar project before, I have experience in working with embedded scanners and windows desktop applications. I see you are looking for a dashboard for the inventory with realtime update. I am not sure how the initial stock is entered into the system is it also through this dashboard? Hmmm or are they part of the other two connected sysmtes? How do we ensure data consistent across all systems. I have few more questions however we can take it in the chat. Please consider my bid. Thanks

Hi, My recommendation would be to build this as a native Windows application using C# and .NET with a local database, providing a simple deployment model while keeping the solution maintainable and responsive. The key areas I would focus on are: • Real-time inventory updates when items are scanned and sold • Reliable synchronization between both checkout counters • Low-stock monitoring with configurable alert thresholds • Dashboard showing sales, inventory levels, and alerts • Daily reporting with PDF/Excel export and basic trend charts • Backup and restore capabilities One important detail I would like to clarify is whether the two checkout counters operate on separate Windows machines or on the same machine with multiple scanners, as this will influence the database and synchronization approach. A typical delivery plan would be: • Prototype and core inventory workflow: 3–5 days • Multi-counter synchronization and testing: 2–3 days • Reporting, charts, documentation, and final polish: 3–4 days I can provide the installer, source code, setup documentation, and a walkthrough of the completed system. Happy to discuss the workflow and deployment approach further. — Nitheesh

@Anas59e

Hi, I've reviewed your full scope including dual-counter sync, barcode-triggered sales, real-time stock deduction, low-stock alerts, daily reports, offline operation on Windows 10/11. Stack: Python + CustomTkinter + SQLite, packaged via PyInstaller + Inno Setup into a clean Windows installer. Two-counter sync: Instead of both counters writing directly to one SQLite file over a network share (risk of locking/corruption), I'll run a small local API service (FastAPI) on one machine as the single source of truth. Both counters connect over LAN, fully offline, no internet needed. Scanners: Standard USB scanners work in HID mode with no drivers needed. Scan input feeds that triggers the sale instantly. Dashboard: Today's sales total, live stock levels, highlighted low-stock alerts based on your custom thresholds. Reports: Auto-generated daily PDF/Excel summaries plus a trend chart for best-sellers. Backup: Simple one-click SQLite backup/restore, covered in the user guide. Milestones:Prototype (5-6 days): login, inventory, barcode sales, stock deduction, alerts, dashboard Live-counter test (3-4 days): LAN API service, both scanners tested live Final polish (3-4 days): reports, installer, backup, user guide Total: ~12-14 days. I've built a similar production system before which is an inventory/sales tracking with live stock tracking, secure login, PDF reporting, packaged as a Windows .exe so these patterns are proven. Happy to discuss further.
