The Client Management System (CMS) is designed to streamline and enhance the management of client-related information for businesses. It includes two primary modules: Admin and Client. The Admin module allows businesses to manage client data, track services offered, generate and print invoices, and review sales reports. It also enables administrators to update their profiles, manage passwords, and recover account information. The Client module, on the other hand, provides clients with a user-friendly interface where they can view and print their invoices, search for invoices, and update their profiles. With automated processes for data entry, invoicing, and reporting, the CMS will help businesses increase operational efficiency, reduce paperwork, and improve client satisfaction through transparent and accessible data management.
