Most institutions seek for improving the performance of their systems, which includes maintaining performance and reducing costs. A key strategy for achieving such goals is the effective implementation of electronic management systems. Also, previous research pointed out that there is a lack of research on the impact of applying electronic management systems on cost at the food and beverage department in hotel establishments. This research explores the impact of applying electronic management systems on food and beverage costs in five-star hotels. This research used questionnaires for collecting data. Four managers were investigated; food and beverage managers and their assistants cost control managers, and financial managers (n=112). Quantitative data obtained were statistically analyzed using SPSS (23). The findings revealed that electronic management systems have a positive effect on costs and developing operational performance. The main contribution of this research is to fill in the literature gap on the impact of electronic management on cost in the food and beverage department.
