By default in POS you can see messages like “Product added to document”, “Product is out of stock” etc. If this is distracting to you or slowing down your process you have the option to hide those messages from your POS.
Find the plugin by going to POS Settings -> Plugins -> Hide alert messages.
Click configure plugin and Add the alert messages that you do NOT want to see in the Global Alert component to the list below. Make sure the message is exactly the same as the alert. The plugin does not support translations, so if you switch the POS language, you also would have to add the message in the new POS language to the configuration below.
After adding this message to the plugin and enabling the plugin, the message you added will no longer appear in POS.
