Portable AppImage
Use the AppImage when you want a portable app that can run on many modern 64-bit Linux distributions without a traditional install step.
Linux invoice app
Invoice Software for Linux
Invoiso gives Linux users a free desktop billing app for invoices, quotations, customers, products, GST fields, UPI QR payments, PDF exports, and local backups. Use the AppImage for a portable build or the DEB package on supported Debian-based systems.
DEB package
Use the DEB build for supported Ubuntu and Debian-based desktops where a system package fits your workflow better.
Desktop PDF invoicing
Create and export PDF invoices from your Linux desktop while keeping data local to your machine.
Useful for Linux users who need
- Invoice and quotation PDFs
- GST-ready invoice fields
- Customer and product records
- Offline-first data storage
- No mandatory cloud account

Installing Invoiso on Linux
Both Linux builds come from the Downloads page. For the AppImage: download
the file, make it executable with chmod +x Invoiso-*.AppImage, then double-click or run it
from a terminal — no package manager, no root permissions, no system files touched. For the DEB build
on Ubuntu or Debian-based distributions, install it with sudo dpkg -i invoiso_*.deb (or
open it directly through your distro's software center) and launch it from your applications menu like
any native app.
Because Invoiso is open source, you can also clone the GitHub repository and run it from source on distributions that fall outside the AppImage/DEB coverage, or audit exactly what the installer does before running it.
Why Linux users choose Invoiso over web-based billing
Most invoicing tools marketed to Indian small businesses — Vyapar, Zoho Invoice, and similar — either skip Linux entirely or only offer a browser-based web app. Invoiso ships a real native desktop build for Linux with the same feature set as Windows and macOS: PDF invoices, GST fields, UPI QR codes, customer and product records, payment tracking, and local backups. There is no browser tab to keep open, no account signup, and no dependency on a hosted service staying online.
AppImage vs. DEB — which build to pick
- AppImage — best if you want a portable, no-install app, use a non-Debian distro (Fedora, Arch, openSUSE), or don't have admin rights on the machine
- DEB package — best on Ubuntu, Linux Mint, or Debian if you want the app registered with your system package manager and listed in your applications menu automatically
Open source, MIT licensed
Invoiso's Linux build comes from the same public repository as every other platform, released under the MIT licence. You can inspect the code, verify there's no telemetry phoning home, and self-host a custom build if your workflow needs it. See the full open-source invoice software page for licence details.
Frequently asked questions
Which Linux distributions does Invoiso support?
The AppImage build runs on most modern 64-bit Linux distributions, including Ubuntu, Fedora, Debian, Pop!_OS, Linux Mint, and Arch-based systems, without a separate install step. The DEB package is built specifically for Ubuntu and other Debian-based distributions that use apt or dpkg.
Do I need root or sudo access to run the AppImage?
No. AppImage files run directly after you mark them executable (chmod +x), with no
system-wide installation and no admin rights required. The DEB package does need sudo since it
registers the app with your system's package manager.
Does Invoiso need an internet connection on Linux?
No. Invoiso is offline-first on every platform, including Linux. Invoices, customers, and products are stored in a local database on your machine, so billing works the same with or without a network connection.
Is the Linux build the same as the Windows and macOS versions?
Yes. Invoiso ships from a single open-source codebase on GitHub, so the Linux, Windows, and macOS builds share the same features — GST fields, UPI QR payments, PDF templates, and backups — with no functionality held back on Linux.
