Project description:
"I need a custom invoicing program that runs smoothly on Windows and offers a user-friendly experience similar to NCH Express Invoice. The core requirements mirror what NCH already does—client database, quote-to-invoice conversion, PDF/email export, basic reporting, and straightforward license activation—so anyone who has built comparable tools will feel right at home.

I’m looking for clean, maintainable code (any modern stack that installs easily on Windows is fine) and a polished UI that non-technical staff can grasp in minutes. If you’ve previously handled invoicing, accounting, or inventory modules on Windows, please highlight that experience in your bid; it will weigh heavily in my decision.

Deliverables will include:
• An installer tested on current Windows 10/11 builds
• Source code with brief build instructions
• A short user guide covering setup, first invoice creation, and backup/restore steps

Payment is released once the installer runs without errors, the guide is clear, and sample invoices generate correctly. Let’s discuss timelines and any additional questions you may have." (client-provided description)
