One of the benefits of Square Terminal is that we keep the software up to date automatically, so you’ll always get the latest features and improvements without any cost. We will update the software every 2-4 weeks. To enable automatic updates, you’ll just need to leave Square Terminal powered on and plugged in overnight. Automatic updates require a battery level of at least 35% to initiate.

Note: Software updates for Square Terminal generally require 2 GB per month. This does not include attempts to retry failed downloads, so it’s recommended to connect to Wi-Fi overnight to help facilitate software updates.

Square Terminal software includes a system update, Square apps update and a firmware update.

If a Square apps update is recommended before the automatic nightly update, a notification will appear on the screen. To defer this update, tap Update Tonight. The update will then begin overnight at 3 a.m. (or at your custom-set time) as long as your Square Terminal is powered on and plugged in. To start the update immediately, tap Install Now.

If you manually update your Square Terminal software from your settings, you will not see an option to defer the Square apps update. The update may take up to 45 minutes to complete.

If you’ve powered down your Square Terminal overnight and there are software updates available, the updates will be applied when you next power on your device. Updates are released approximately every 2-4 weeks, involve a reboot of Square Terminal and typically take around 20 minutes to complete, but may take up to an hour.

To ensure your Square Terminal can update overnight – just make sure it’s plugged in and 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.

You can check your software at any time. Head to ≡ More > Settings > Hardware > General. Scroll to the bottom of the page and tap About Terminal. From this page, you’ll see your software version and available updates.

Most software updates should happen automatically every 2-4 weeks and will happen overnight, as long as your Square Terminal is plugged in and powered on, and the battery level is at least 35%.

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 the updates includes a full reboot of your device.

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 plugged in and 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. If you need to adjust your nightly reboot time, head to ≡ More > Settings > Hardware > General from navigation bar at the bottom of your screen. Tap Nightly Reboot and select the time that works best for your business.

Note: This adjustment will not take effect on the next nightly reboot, but instead the one after that.
