Yes! You can accept joe orders directly through your Square POS without any additional hardware.  All joe refunds, inventory changes, and menu updates MUST be done through the joe app, not through Square.

If you operate your Square POS on an iPad with a Square stand (pictured above), you will need to download the joe app directly to the iOS device.

If you operate with the full Square Register system (pictured above), you will need to download the joe app to a separate device to initially link the accounts.  You will not need this device to accept or fulfill orders, but any joe refunds, inventory changes, and menu updates MUST be made through the joe app, not through Square.
