Hey Product Hunt 👋
I built InvoiceOS after running into something that kept bothering me with most invoicing tools.
Many tools say you “own your data”, but in reality the data still lives inside their platform. If you stop paying the subscription, you often lose access to your own invoices or documents.
I ran into this myself while trying to retrieve an old document from an accounting tool. Even though it was my data, I needed to subscribe again just to access it.
That didn’t sit right with me.
So I started experimenting with a different idea:
What if the invoices simply lived in your own Google Sheets, while the app handled the interface and automation?
That’s how InvoiceOS came about. It’s a lightweight invoicing tool that lets you:
1) create invoices
2) generate PDFs
3) track unpaid payments
4) send reminders
But the key difference is that your data stays in your own Google Sheets, not locked inside another SaaS database.
The goal was simple: keep invoicing clean, transparent, and under the user’s control.
Would love to hear your thoughts or feedback 🙏
