Look for software with a user-friendly graphical interface. Your POS system should be easy to set up, simple to use and easy to navigate. The point of sale system should have an intuitive interface to process sales quickly and run your day-to-day operations. Therefore, training staff should be simple and not overwhelming. Managing inventory and setting up the system to fit your needs should be straightforward. Keep in mind that POS systems are intended to increase effectiveness; you don’t want complicated systems that will decrease employee satisfaction and waste time.
