The Qubes company of Saudi Arabia faces similar challegnes. The adoption of an improved sales forecasting mechanism can soundly help Qubes and/or other such companies maintain adequate stocks, minimize the likelihood of stockout situations, and in effect improve their customer satisfaction. To address such challenges, a forecasting and inventory management interface is designed and developed. The interface is linked with the demand/sale’s historical data, the forecasting techniques, and forecasting results. The main characteristics of the interface includes its user friendliness, easiness of data entry, graphical highlights, and the important quantitative indicators. The future period demand, safety stock, reorder point, and location-wise demand distributions of different products can be grasped through one-shot click and displayed at single screen. The presented forecasting-based inventory solution can improve resource utilization, reduce waste, and promote sustainable businesses. The interface can globally be utilized by different businesses, especially the start-ups, having their historical demand/sales data of one year. The interface offers results within 10% error in forecasting as compared to historical figures. Moreover, the inventory solution and the reliability of the dashboard is validated through three different cases; 1) preparing for high demands during seasonal peaks, 2) Supplier lead time issues with varying lead times, and 3) a case of launching a new product. Hence, the inventory solution and the designed dashboard are considered as the sustainable with global impact on business economy through controlling overstocking and understocking.
