Starbucks has gone through a couple of systems over the years. In the early days, it relied on Square POS and essentially put it on the map. However, in order to satisfy the growing demands of its business, Starbucks switched to Oracle’s MICROS Simphony system that was built specifically with restaurants in mind. Nowadays, it relies on LSRetail's award-winning product that many users consider to be one of the best restaurant POS systems for high-end businesses.
