Electronic ordering software is specially designed for hotel customers who want to keep the traditional handwritten list. After the waiter records the ordering information of the diners through the handwritten list, he can enter the ordering information into the "easy-to-manage" catering system through touch screen entry machines distributed on all floors and points of the hotel, which saves the trouble of running around and handing out leaflets and facilitates the statistics and analysis of daily business data. The software I used in Beijing Tiancan is very practical, and my income is much better than before.
