SoloStack - Free financial tools for freelancers to maximize profit.

Hey Product Hunt! 👋 I'm Steven, the maker behind SoloStack. As a freelancer, I realized I was spending 20% of my time doing the work and 80% stressing about the business side—guessing my hourly rate, under-quoting fixed projects, and losing track of expenses. I looked for tools to help, but everything was either behind a paywall or overly complex enterprise software. So I built SoloStack: A suite of 5+ privacy-first, completely free utilities designed to help independent pros master their math. 🚀 What's Inside? Rate Calculator: Works backward from your dream salary to find your true hourly rate. Project Pricing: Templates to estimate Logo, Web, and Copy projects accurately. Profit Tracker: Visualizes your margins and improved 'take-home' pay. Invoice Generator: Simple, professional PDF invoicing. It’s 100% free, no signup required. I’d love to hear what tools you think I should add next! Cheers, Steven"
