Systematic Invoice

Install

System requirements

  • macOS: 12 or later, on Apple silicon or Intel.
  • Windows: 10 or 11, 64-bit.
  • Linux: 64-bit, on x64 or ARM. Tested on Ubuntu 22.04 and later.

Systematic Invoice is free. It needs no account, shows no ads, and every feature is included.

Install on macOS

  1. Download the .dmg for your Mac: Apple silicon for M1 and later, Intel for older Macs. Not sure? Open the Apple menu, choose About This Mac, and look for Chip (Apple silicon) or Processor (Intel).
  2. Open the .dmg and drag Systematic Invoice to Applications.
  3. Open it from Applications. The app is signed and notarized by Apple, so it opens like any other app.

Install on Windows

  1. Download the installer (.exe) and run it. It installs for your user account and needs no administrator rights.
  2. If Windows shows Windows protected your PC, choose More info, then Run anyway.
  3. Open Systematic Invoice from the Start menu or the desktop shortcut.

Install on Linux

  • Debian, Ubuntu and similar: download the .deb and install it with sudo apt install ./SystematicInvoice-*.deb, then open it from your applications menu.
  • Any distribution: download the AppImage, make it executable with chmod +x SystematicInvoice-*.AppImage, and run it.

Every Linux download: x64 .deb, x64 AppImage, ARM .deb, ARM AppImage.

First launch

  1. Choose where your records live. On the Local tab, create a new database: one file on your computer, ideal for one person. On the Server tab, connect to a PostgreSQL database instead, so several people can work on the same records at once. You can open another database later. See Your data.
  2. The language follows your computer when it is English, French or Arabic. Change it any time in Settings → Language & Format, where you also choose how amounts and dates are written.
  3. Choose your default currency in the same place. Totals on the dashboard and in the reports are shown in it, and every other currency gets a rate to it. Choose it before your first invoice: once you have invoices or quotes, it no longer changes.

Your first invoice

  1. Add your business under Businesses: name, a two-letter short name, address, VAT number and logo.
  2. Add a client under Clients, and your products or services under Items, with their prices and units.
  3. Add your banks and wallets under Banks and wallets, so the invoice says how to pay you.
  4. Open Invoices and choose Add. Pick the business, the client and the currency, add the lines, and save. The number is given for you.
  5. Switch to Preview to see the PDF as your client will, then print it or save it.

First steps shows your way around the app, and Invoices explains every part of an invoice.

Updates

The app looks for a new version shortly after it opens, then every few hours. It downloads it in the background and asks you to restart when it is ready; if you choose later, it installs the next time you quit. You can also check yourself in Settings.

Uninstall

  • macOS: move Systematic Invoice from Applications to the Bin.
  • Windows: open Settings → Apps, find Systematic Invoice and choose Uninstall.
  • Linux: run sudo apt remove systematic-invoice, or delete the AppImage.

Uninstalling never deletes your database file or your backups: they stay where you saved them.
