When Invoiso reached 1,000 downloads, I considered it a small milestone that meant a lot.
Now it has crossed 10,000 downloads, and honestly, it's difficult to put that feeling into words.
Invoiso started in July 2025 as a simple offline invoice maker. What started as a small weekend project has gradually grown into a complete billing application, largely because of feedback from its users.
And the journey is far from over.
🧾 From a Simple Invoice Maker to a Complete Billing Tool
Today, Invoiso supports much more than creating a basic invoice.
Invoicing
- Invoices, quotations and payment receipts
- GST document types
- Custom invoice numbering
- Custom fields
- Per-line descriptions
- Tax-inclusive pricing
- Per-item tax
- CGST / SGST / IGST
- Invoice-level discounts
- Charges and adjustments
- Document cloning
- Bulk actions
- Unsaved-change warnings
Many of these features came from actual user requests.

🌍 Making It Useful Around the World

❌ No requirement to upload your business data
Your data stays on your machine.

Windows • Linux • macOS
🛠️ Built Mostly During Evenings and Weekends
One of the things that makes this milestone special to me is how Invoiso was built.
It wasn't started as a big company project.
It started as a simple idea and gradually grew through development during evenings, weekends, and whatever free time I could find.
There were plenty of bugs.
There were features that needed to be redesigned.
There were releases that didn't go exactly as planned.
And there were lots of messages saying:
"Can you add this feature?"
Some of those requests eventually became part of the application.
That's one of my favourite parts of building an open-source project.
❤️ Thank You
To everyone who has:
- Downloaded Invoiso
- Reported a bug
- Requested a feature
- Suggested an improvement
- Translated the application
- Tested new releases
- Shared Invoiso with someone
- Starred the GitHub repository
- Or simply sent a message saying that it was useful
Thank you.
10,000 downloads isn't just a number to me.
It's 10,000+ opportunities for the project to be useful to someone.
And it gives me a lot of motivation to keep building.
🚀 What's Next?
There are still many things I want to improve.
More features.
Better UX.
Better documentation.
More languages.
More integrations.
And, of course, plenty of bugs waiting to be discovered. 😄
On to the next 10K! 🚀
