<![CDATA[Abstract. PT Lucas Djaja has experienced a downward trend in sales due to the lack of an integrated digital customer information system, relying instead on conventional transactions and communication methods. This study aims to design an e-commerce-based Customer Relationship Management (CRM) system to automate information acquisition and provide digital communication channels.

In conclusion, implementing a CRM system using PrestaShop and Tawk.to offers a strategic solution to overcome operational issues, enhance work efficiency, and strengthen customer loyalty at PT Lucas Djaja.
