Most software updates should happen automatically every 2-4 weeks and will happen overnight as long as your Terminal is plugged in and on.

However, sometimes, we have a critical update that should be installed more urgently. When that happens, you’ll see Update Available in your status bar to install immediately. Installing an update includes a full reboot of your device and about 10–15 minutes of total downtime.

If your business doesn’t allow you to update Square Terminal right away, it will go through the normal update process overnight - just make sure it’s powered on, but the display can be turned off. To turn off the display, simply tap the power button quickly and Square Terminal will go to sleep.

Software updates are, by default, set at 3 a.m. to avoid any disruption to your normal business hours.

To adjust your nightly reboot time on your Square Terminal:

If you’ve powered down your Square Terminal overnight and there is a software update available, the update will be applied when you next power on your device. Updates involve a reboot of Square Terminal and about 10-15 minutes of downtime and are released approximately every 2 - 4 weeks.
