Hello, I can build this Windows desktop application with a clean and scalable architecture using .NET and SQLite. I have experience developing inventory, invoicing, and business management systems with real-time stock handling and PDF reporting. The application will include: Real-time inventory tracking with automatic stock deduction on invoice posting Fully customizable invoice templates (logo, colors, fonts, columns, layouts) PDF export with accurate template styling Sales, inventory valuation, and low-stock reports SQLite local database with offline support Installer/portable EXE for Windows 10/11 I will provide well-structured source code, database scripts, and a quick-start PDF guide. The codebase will also be designed for future expansion to web or cross-platform solutions. I can start immediately and deliver a professional, user-friendly solution. Thank you.

I have read your job post and I can build a standalone Windows application for invoicing and real-time inventory management. I am a software developer experienced in desktop application development, database design (SQLite), and building reliable business tools with clean architecture and offline functionality. My approach will be to develop a lightweight Windows app that combines inventory tracking and invoicing in one system. Stock will update automatically whenever an invoice is created, with support for adding/editing products, recording stock in/out, and low-stock alerts. I will also build fully customizable invoice templates where you can add your logo, adjust layout, colors, fonts, and save multiple designs. The system will include PDF export with accurate formatting, basic reporting for sales and inventory valuation, and a simple, clean UI for daily use. The code will be structured in a portable way so future expansion to web or macOS remains easy.

Hi, Your project fits very well with my experience in business management systems and scalable desktop software architecture. I can build a lightweight Windows 10/11 invoice & inventory application with: • Real-time stock tracking and automatic stock deduction • Professional invoice generation with customizable templates • Logo, color, font, and column customization • Multiple invoice template support • PDF export with accurate styling preservation • SQLite local database integration • Low-stock alerts and inventory valuation reports • Clean modular architecture for future web/macOS expansion I focus on clean UI, reliable inventory logic, and maintainable code rather than quick temporary solutions. Deliverables will include: • Windows installer or portable EXE • Source code with comments • SQLite database setup • Quick-start PDF guide • Editable invoice template examples A few questions before starting: 1. Do you prefer C#/.NET desktop or cross-platform stack like Flutter/Electron? 2. Should invoices support GST/tax calculations? 3. Do you need barcode support for inventory items? 4. Single-user or multi-user local access? 5. Any preferred invoice paper size (A4/Thermal)? Looking forward to discussing the architecture and workflow. Thanks

Hi, I can build a self-contained Windows invoice and inventory software with SQLite database, automatic stock deduction on invoice posting, editable invoice templates, PDF export, and month-end reporting. The application will support item master management, stock in/out entries, low-stock alerts, customizable invoice layouts with logo/colors/fonts/columns, and at least two editable template designs. I will provide a Windows installer or portable EXE, database script, source code, and a quick-start PDF guide. The code will be kept modular so future expansion to web or macOS is easier. I have experience building business automation and invoice/reporting tools, so I understand the need for stock accuracy, smooth workflows, and maintainable software.

@Baghali1

Hello, I have read your project description and analyze your requirements. I am a flutter developer. I can develop your desktop app. Later you can also use for mobile Android and iOS and Macos with single codebase. Same UI no need of other programing language. With same language all plateform work perfectly. Local database is used SQL and hive which you prefer. I am waiting for your response.

@omp589

Hi there! I’ve reviewed your requirements and am ready to deliver a high-performance Windows application tailored to your needs. While your current focus is desktop, I will build the system using a cross-platform framework—ensuring that it can be seamlessly deployed to Android and iOS in the future without a complete rebuild. I have successfully developed similar software for medical inventory management with invoicing, ensuring high precision and ease of use in fast-paced environments. That application will support cross platform (Android and iOS) as well. I have almost ready made things for this project. Ping me for further discussion. Thanks!

I propose building a modern Windows desktop invoicing and inventory management application using C#/.NET/Qt/PySide6 with a clean layered architecture for future portability. The system will include real-time stock tracking, customizable invoice templates, automatic inventory deduction when invoices are finalized, PDF export with pixel-accurate template rendering, and SQLite local storage for fully offline operation. The application will ship as a Windows 10/11 installer or portable executable with no external server dependencies. Key features will include: Product and inventory management with stock alerts Invoice creation with editable templates, logo upload, custom fonts/colors, and multi-template support Automatic stock synchronization tied to invoice posting PDF export preserving invoice layout exactly Sales, inventory valuation, and low-stock reports Clean, commented source code and database schema Structured codebase designed for future migration to web or macOS platforms Deliverables will include: Windows installer / portable EXE SQLite database schema Fully documented source code Quick-start PDF user guide At least two editable invoice template examples The solution will prioritize stability, maintainability, and ease of future expansion while remaining lightweight and fully self-contained for end users.

Hello, I understand you need a self-contained Windows application for issuing professional invoices with a built-in inventory system that tracks stock in real time and updates automatically when invoices are generated. The goal is to deliver a reliable, lightweight, and user-friendly desktop solution for seamless billing and stock management. Here’s what I can provide: * Real-time inventory tracking with automatic stock deduction on each invoice * Fully customizable invoice templates (logo, colors, fonts, multiple layouts) * PDF export with accurate 1:1 design preservation using a local SQLite database I bring over 4+ years of experience in Windows desktop application development, working with VB/.NET, SQLite, and inventory management systems. I focus on building stable, scalable, and cleanly structured software that can be easily expanded in the future (web or cross-platform if needed). Just to clarify a few things: * Do you prefer VB.NET or C# (WPF/WinForms) for this project? * Should the system include GST/tax calculations or remain basic invoicing only? Please come to the chat box to discuss more about your project. Best regards Indresh Kushwaha

Primary: Tauri + Rust Rust handles business logic — inventory, invoicing, stock deduction, alerts — with SQLite as the local database. Templates are plain HTML/CSS, editable without recompiling. PDF export uses Tauri's native print pipeline. Output is a single ~8 MB portable EXE; WebView2 is the only dependency, bundled with Windows 11 and auto-installed on Windows 10. Estimated delivery: 6 weeks. Fallback: Python + PySide6 Covers every requirement with less friction. QWebEngineView renders templates live, QPrinter exports to PDF, sqlite3 handles the database out of the box. PyInstaller produces a single EXE (~35 MB). Faster development, heavier binary. Delivery schedule (4h/day, ~20h/week) Week 1 — App scaffold, SQLite schema, migrations, data models. Week 2 — Inventory UI: add/edit items, deliveries, sales, low-stock config. Week 3 — Invoicing core: line items, customer fields, stock deduction on post. Week 4 — Two HTML/CSS templates, logo/font/colour customisation, PDF export. Week 5 — Reports: sales totals, inventory valuation, low-stock alerts. Week 6 — Edge cases, error states, testing, quick-start guide, portable EXE verification. Total: ~6 weeks / ~120 hours The total fixed price for this project is £10,000 (~$12,600 / ₹1,050,000), inclusive of all deliverables outlined above.
