Disclosed herein are system, method, and computer program product embodiments for a cloud-based point-of-sale system and a multi-function point-of-sale (POS) device. In an embodiment, the POS device includes an interactive display that switches between a first position oriented towards and for use by an operating clerk, and a second position oriented towards and for use by a customer. The POS device is able to detect the switch between the first position and the second position. A processor in the POS device outputs a first graphical user interface (GUI) on the interactive display in response to detection of the first position and a second GUI in response to detection of the second position. In an embodiment, the components of the POS device are combined together in a unified assembly.
