In a restaurant business process, of course, it involves many roles such as the role of a waiter, the role of a chef, the internal role of the raw material stock section, and so on are interrelated and must be synchronized. However, in practice, restaurants still use conventional methods that are inefficient, effective, and structured. Some restaurants in the city of Medan only use conventional records both in ordering and recording raw material stocks so that errors often occur due to the inaccurate calculation process.
