Square vs RestaurantOS — which fits your restaurant?

Square is a US-origin payments + POS platform. No setup or monthly fee — start with payment fees only — plus restaurant features like table management and a kitchen display. RestaurantOS is an integration platform that runs POS with the plugins you need on one OS. This page lays out the differences using public information.
