Invoiso Crossed 1,000+ Downloads from the Official Website

1,000+ downloads. Wow 🎉🎉🎉🎉.

For a massive tech company, that’s a rounding error. But for a free, open-source project built on nights and weekends? It feels absolutely massive.

I originally built Invoiso because I was tired of how complicated invoicing had become. It felt like every tool out there wanted me to sign up for a monthly subscription, create an account just to test it, and hand over my data to their cloud.

I wanted something different. I believed in a simple idea: your business data should stay with you.

No forced cloud. No monthly fees. No gatekeeping. Just a dependable desktop app that lets you get your work done, save your PDFs, track your payments, and go home.

What actually is Invoiso?

It’s a completely free, offline-first invoice and billing app for Windows, Linux, and macOS. I built it using Flutter and SQLite, keeping it lightweight, fast, and local. It’s tailored for freelancers, small business owners, consultants, or anyone who just wants a practical tool without the subscription trap.

Here is what it can actually do right now:

Professional PDFs: Create clean invoices and quotes with Classic, Modern, or Minimal templates.
Keep Organized: Track customer details, manage products/inventory, and log payments.
Smart Extras: Multi-currency support, CSV exports, and local backup/restore.
Built for India: Includes GST-ready fields and automatically generates UPI QR codes right inside the invoice PDFs so you can get paid faster.

Why this milestone means so much to me

1,000 downloads means real people are actually trusting this app with their daily business workflows.

As a solo developer, that is the ultimate fuel. Every single download, bug report, and feature suggestion helps make the app better. I’m incredibly grateful to the early users who ran into bugs, reached out, and helped me polish the rough edges.
