This document describes the implementation of a customer relationship management (CRM) system with sales modules. The system was developed to help organizations increase customer retention rates and improve work performance. It includes modules for lead management, product management, quotation management, customer management, order management, and report management. The modules work together to track customer and sales data in an efficient and organized manner. For example, the lead management module tracks potential customers and their information can be used in other modules. The report management module allows users to generate reports from the data collected in the other modules. The full system is meant to provide a centralized way for organizations to manage all information related to customers, sales, and business performance.
