FluxInvoice - Free, private invoice generator & rate calculator.

Hello Product Hunt, I am excited to share FluxInvoice with the community today. While researching tools for freelancers, I noticed a significant gap in the market: the vast majority of invoice generators either require a paid subscription, mandate user registration, or compromise client privacy by storing data on external servers. FluxInvoice was built to solve this. It is a completely free, privacy-first invoice generator and hourly rate calculator. Key Features: 1. No Accounts Required: Users can generate and download PDF invoices instantly. 2. 100% Private: The application runs entirely in the browser. All invoice history and client data are saved exclusively to the user's local storage. 3. Rate Calculator: A built-in tool to help independent contractors calculate sustainable hourly rates based on expenses and target income. 4. Mobile Optimized: A fully responsive interface that allows users to create invoices seamlessly from their phones. My goal was to create a high-quality, frictionless utility for independent professionals. I welcome any technical feedback, feature requests, or questions you might have about the build!
