Download TechDesk
Sales, repairs, inventory, customers and reports, on the computer at the counter. It works with the internet off, and it is free to use for as long as you like.
Free to use, with no trial and nothing that expires. Staff accounts and clean receipts are part of Business, and head office is part of Enterprise — they unlock in this same install, so there is never a second thing to download. Looking for the phone app? TechDesk for Android.
Ubuntu: if the installer sits on “Installing”
Ubuntu’s App Center often hangs forever on downloaded .deb files — it is the store doing that, not the package. Close it and install from the terminal instead, which takes about ten seconds:
cd ~/Downloads
sudo apt install ./techdesk_*_amd64.deb
Then find TechDesk in your applications, or type techdesk.
If App Center is still stuck, cancel it first:
sudo killall appcenter, then
sudo dpkg --configure -a.
The AppImage avoids all of this — download it, right-click → Properties → tick Allow executing file as program, and double-click it. Nothing is installed and nothing can hang.
