## Overview

Perfex is a web-based CRM and business-management application. Staff and customers enter through separate administrative and client-facing interfaces; users manage CRM records and operational work such as projects, tasks, estimates, and proposals, with related capabilities for billing, payments, support, and subscriptions. The graph also shows the shared Kanban and framework layers, plus documented integrations and extensions. Evidence is limited to the supplied excerpts and source index; major subsystems visible in the tree but not sampled are included without speculative call relationships.

Main entry points: [`application/controllers/Clients.php`](https://github.com/pltechchandra/nextgenlive/blob/main/application/controllers/Clients.php) (Client records), [`application/controllers/admin`](https://github.com/pltechchandra/nextgenlive/tree/main/application/controllers/admin) (Admin controllers), [`application/core/ClientsController.php`](https://github.com/pltechchandra/nextgenlive/blob/main/application/core/ClientsController.php) (Client controller base), [`modules/fixed_equipment/controllers/Fixed_equipment_client.php`](https://github.com/pltechchandra/nextgenlive/blob/main/modules/fixed_equipment/controllers/Fixed_equipment_client.php) (Equipment client)
