Desktop invoicing you own forever - no subscriptions - OwnInvoice by Grit Software

Hey Product Hunt! I'm Joe, a 23-year-old solo dev who just launched my first product. Built this nights and weekends over the last 3 months while working full-time IT. Why I built OwnInvoice: I was paying $30/month for invoicing software I knew I'd use forever. After a year, that's $360 for something that could just... exist on my computer. So I built an alternative. What makes it different: Desktop app (Mac & Windows) - works completely offline One-time $199 purchase - no subscriptions, no monthly fees 5 payment gateway integrations (Stripe, PayPal, Square, GoCardless, Authorize.Net) Your data stays on your computer, not someone else's cloud Free lifetime updates The tech: Built with Electron, React, and SQLite. Took way longer than I expected (doesn't it always?), but learned a ton about desktop app development, payment integrations, and shipping real software. What I'm learning: This is my first real product launch. Goal isn't to scale massively right now - just validate there's a market for one-time purchase business software in 2026. If I can get 3 sales in 3 weeks, I'll know I'm onto something. I'd love your feedback on: Does the $199 pricing make sense vs $30/month subscriptions? What features would make this a must-have for you? How does the anti-subscription positioning land? Happy to answer any questions about the product, the build process, or solo dev life!
