Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 51.88 MB, so it installs quickly even on modest connections.
This build is signed by "Invoice Ninja" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

Frequently Asked Questions

Is Invoice Ninja free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does Invoice Ninja require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is Invoice Ninja safe to install?

How do I update Invoice Ninja?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
