Let me help you find the right app, szirabamuzale.

There are several POS systems that integrate with QuickBooks Online. You can go to your Apps menu or use this link to find one: Apps help QuickBooks run better.

If your POS system isn't listed in the apps menu, you can still use it, but you'll need to use a third-party app connector to connect it to QuickBooks Online.

Let me know if you still have other questions about QuickBooks Online. I'll be here to help.
