The Electric and Electronic manufacturing companies are among industries that need forecasting the most. The need to forecast in the management and operations is increasing in order to achieve its objectives. The company currently facing the problem of over produce inventory for some of the product and the problem might be due to inconsistent demand. Thus, data pattern of inventory demand need to identify before choosing the forecasting methods. Comparison among methods was conducted to determine the best method for the company in order to prepare them for future inventory. This study was conducted using the case study method. The data of demand for one of the product series for five consecutive years were collected and forecasted using Risk Simulator software for the purpose of this study. From the result, the selected forecasting methods to implement were: Single Moving Average, Single Exponential Smoothing, Double Exponential Smoothing, Double Moving Average, Regression Analysis and ARIMA (Autoregressive Integrated Moving Average). It were selected based on the trend and cyclical data patterns. The finding revealed that, Single Moving Average method is the best forecasting method when comparison forecast accuracy is made
