Sales of goods at the Casa Mia Store are erratic, often the Casa Mia Store experiences stock shortages and excess stock. Too much inventory means investing large amounts of capital that are stuck in inventory. Therefore, in order to run smoothly the process of controlling stock needs for ceramics which have different sales levels, it is necessary to use a method to find out the amount of ceramic needs needed in the future, so that the available ceramic stock does not experience problems or overstock. So this research will predict the need for ceramics at the Casa Mia Store by applying the Holt Winters Exponential Smoothing method. Based on the test results by comparing real ceramic sales data and data from predictions of ceramic demand for the 2024 period, it was found that the presentation of Holt Winters Exponential Smoothing predictions achieved the highest average accuracy at the 30x30 size of 96.44%, while the 40x40 size achieved an average accuracy of 95.98% and the size 60x60 gets an average accuracy of 95.43%. For this reason, the prediction results can be a reference for optimizing the ceramic needs of the Casa Mia Store in order to avoid losses and maximize profits.
