I’m looking to have a full-featured point-of-sale application built for Windows PCs that I can distribute to my own clients. They will install it locally, enjoy a 3-month free trial, and then move automatically to a paid monthly subscription, so licence management has to be baked in from day one. The user must be able to tailor three key areas on their own—interface layout, report generation, and inventory management—without calling a developer each time. Within the sales screen the software should accept Credit/Debit Cards, Mobile Payments, and Cash, storing each transaction type separately for reporting purposes. What I need from you: • An installer for Windows that runs cleanly on standard PC-based POS hardware • A licensing / activation module that starts the clock on the 3-month trial, switches to a paid plan afterwards, and blocks access if payment lapses • Clear admin screens so I can onboard new merchants, reset licences and push updates • Source code and practical documentation so future enhancements stay in my control If you’ve built POS systems in C#, .NET, Java or similar desktop stacks and can demonstrate secure payment integrations, I’m eager to hear how you would structure the project and timeframe.

Hello, I hope you are doing well. I’m a desktop software engineer with extensive .NET/C# experience, focusing on robust Windows POS systems with built-in licensing. I design configurable apps where merchants tailor interface, reports, and inventory without a developer, starting with a secure 3-month trial. I’ve built similar POS solutions in C#, .NET, with multi-tender sales (cards, mobile, cash) and separate per-tender reporting, MSI/installer packaging, license activation, and admin consoles for onboarding and updates. Source code and practical docs accompany every delivery. I can deliver end-to-end: installer, licensing flow transitioning from trial to paid, offline license checks, admin screens, and full source + docs. The project will be modular for the three customization areas and secure payment integrations. Please feel free to contact me so we can discuss details. I am looking forward to working together.

Hello, I’ve built and architected desktop POS and business-critical applications where licensing, offline reliability, and long-term maintainability were non-negotiable — so your requirements align very well with how I normally structure projects. Rather than just “coding screens,” I’d approach this as a distributable commercial product from day one. Proposed Architecture Windows desktop application (C#/.NET – WPF or WinUI depending on hardware needs) Local database (SQLite / SQL Server Express) with clean migration strategy Modular design so UI, licensing, payments, and reporting evolve independently Key Features Breakdown 1. Installer & Deployment 2. Licensing & Subscription Management 3-month trial starting on first launch 4. Sales & Payments 5. Admin & Control Panel Timeline (High-Level) Architecture & UX planning: 1–2 weeks Core POS + inventory + reporting: 6–8 weeks Licensing & payments: 2–3 weeks Testing, installer, polish: 2 weeks I’m happy to discuss: If you’re looking for someone who thinks beyond “version 1” and builds a POS you can confidently distribute and monetize, I’d be glad to walk you through a concrete plan.
