Abstract

The development of information technology offers significant opportunities for businesses to improve operational efficiency, including inventory management. Toko Reza Sukses, a clothing retail business, faces challenges in balancing stock levels with customer demand. This imbalance can lead to overstocking or stockouts, resulting in losses and decreased customer satisfaction. This study aims to apply the Double Exponential Smoothing (DES) method to forecast stock requirements based on historical data. DES was chosen for its ability to capture upward or downward trends in sales data. The system is designed as a web-based application using the PHP programming language to facilitate an effective and efficient forecasting process. The implementation results show that the system is capable of providing more accurate stock estimates, reducing instances of stock shortages and surpluses, and enhancing customer satisfaction through better product availability.

Abstract

The advancement of information technology has encouraged business actors, including retail stores such as Wulan Busana, to adopt more effective systems for managing customer relationships. One relevant solution is the implementation of Electronic Customer Relationship Management (e-CRM) to enhance customer loyalty and satisfaction. This study aims to design and implement a web-based e-CRM system at Wulan Busana store using the CodeIgniter framework. The method used is qualitative, with data collection techniques including observation, interviews, and literature review. The results of the study show that the e-CRM system helps the store manage customer data, monitor product stock, and carry out marketing activities in a more structured and efficient manner. The implementation of this system has proven to enhance interaction between the store and customers, accelerate responses to customer needs, and simplify promotional and sales evaluation processes. The system also has a positive impact on increasing customer loyalty and improving the store’s operational efficiency.
