jeffkatz/quotevoice ? reverse-engineered prompt

Build me a Windows desktop app for freelance invoicing and quotes called Quotevoice.

I want a simple app where I can store my business details, upload my logo, add clients, and create professional invoices or quotations with automatic numbering. It should calculate line items, VAT, subtotals, and totals for me, use Rand by default, and be set up for South African business details and tax. I also want a dashboard that shows things like total revenue, overdue invoices, drafts, and recent documents.

Please make it easy to preview a document, then download it as a PDF or print it straight from the app. All data should be saved locally so it works offline. I’d like a clean, modern interface with sidebar navigation for Dashboard, Documents, Clients, and Settings. If you need to check current docs for Electron or PDF handling, go ahead and look them up online.
