An offline Invoice Ninja alternative with no server and no account

Invoice Ninja is an open-source invoicing platform — capable, but it still needs a server (cloud or self-hosted) and an account. InvoicePro is simpler: one HTML file, runs in your browser, makes invoices and quotes offline with nothing uploaded.

No account, ever Pay once, own it EN + 繁體中文

Open source vs. offline-file: a different kind of private

Invoice Ninja is a well-respected open-source invoicing solution. You can use the hosted cloud version (account required) or self-host it (server required). Either way, there is infrastructure to run and data stored somewhere.

InvoicePro is the minimal alternative: a single HTML file with no server at all. Open it in any browser and you have invoicing — logo, tax, discounts, 12 currencies and four layouts — stored entirely in your browser's local storage. Pay $9 once for Pro. There is nothing to host, maintain or log in to.

Frequently asked questions

Is InvoicePro free?
Yes. The free version makes a complete invoice in your browser with no account. A one-time $9 Pro version adds quotes, all four layouts and removes the watermark.
Is it an Invoice Ninja replacement?
For solo freelancer invoicing — yes. It is not a full platform with recurring invoices, client portals or multi-user access.
Do I need to install anything?
No. It is a single HTML file that runs in any browser.
Is my data private?
Completely. Nothing is uploaded — it all stays on your computer.
Can I export for my accountant?
Yes. Export a CSV or print a PDF.
