Hello! Ready to turn your invoice routine into a fast, clean, one-screen WinForms or WPF desktop app that prints or exports PDFs with a single click. You’ll get a compact UI to enter invoice number, date, client name, line-items, and totals, plus a dedicated payment-terms section visible on every generated invoice. I’ll build it with standard .NET tooling so you can open the Visual Studio solution today and extend it later. Deliverables include a well-commented C# project, an installer or portable .exe for Windows 10/11, and a quick-start readme covering setup, dependencies, and how to edit the payment-terms text. The app will generate professional output that clearly shows terms on the final PDF or printout, with totals calculated reliably for multiple line items. I’ll document the chosen PDF/print library and the setup steps, so you can reproduce builds easily. Let’s go from zero to invoices in seconds with a polished, distraction-free interface that keeps everything in one place. Best regards,

For a WPF invoice generator, I would wire up the input form, hook in PDF output via iTextSharp, and add a print preview so invoices look right before they go out. I can have a working version ready in 3 days. Pricing shown is based on the post as written. Once we walk through the full feature list, the final numbers may shift in either direction. Can start today. Want me to send a quick scope doc so we can get moving?

@AshtonPietersee

Hey — saw your post about a C# desktop invoice generator. Most invoicing tools get annoying fast when simple things like editing line items or taxes take too many clicks. Quick question before I suggest an approach: Do you need these invoices stored locally in a database (e.g. SQLite) for later search/filter, or is it enough to just generate and export PDFs on demand? I’ve built small C# desktop tools for billing and internal admin tasks, including invoice-style PDF generation with custom fields and branding. If you can share any sample invoice, fields you need, or a rough spec, I’ll review it and suggest a clean, minimal setup that fits what you’re after.

⭐⭐⭐⭐⭐ Senior C# Desktop Application Developer ⭐⭐⭐⭐⭐ Hello there, I am a C# developer specialising in clean, focused Windows desktop applications built with WPF and standard .NET tooling. A single-screen invoice generator done well requires careful attention to the PDF output layout — professional invoice presentation means consistent column alignment, clear line-item totals, and payment terms displayed exactly as entered, which is where basic PDF libraries often produce disappointing results without deliberate template design. Built WPF desktop applications with PDF generation using QuestPDF or FastReport Free — both license-friendly and well-documented. Invoice number, date, client details, line items with automatic total calculation, and a payment terms section are all straightforward to implement cleanly in a single-screen WinForms or WPF layout. Deliverables include the full Visual Studio solution with commented source, a portable .exe ready for Windows 10/11, and a readme covering build steps, dependencies, and how to edit payment terms text. Turnaround: 2–3 days. Do you have a preferred invoice layout in mind — a specific column structure or branding elements like a logo — or should I propose a clean professional template as the starting point?
