Business owners are leveraging advancements in information technology to simplify sales and inventory management amidst dynamic business competition. Toko Roti Soes Merdeka, a MSME specializing in bread and cake sales, faces challenges in managing stock availability without causing excess or shortage of inventory. To address these problems, this study designs a web-based decision support system using the Weighted Moving Average (WMA) method to forecast sales based on historical data collected from May 18–24, 2025. The WMA method assigns different weights to each period, resulting in more accurate predictions in determining stock requirements for the following period. The results show that the developed system effectively assists with transaction recording, stock management, and presenting forecasting results automatically and in a structured manner. Ultimately, this system supports more effective and efficient decision-making for inventory management.
