IT Service Management CRM Development

I need a custom IT Service Management (ITSM) CRM designed for IT-related businesses. The CRM should include features like ticketing system, client management, project tracking, asset management, automated workflows, and reporting/analytics. It should be web-based with a user-friendly interface, role-based access, and API integration options for third-party tools.

Key Features:

Ticketing System (issue tracking, priority levels, SLA management)
Client & Contact Management
Project & Task Management
IT Asset Tracking
Automated Workflows & Notifications
User Roles & Permissions
Reports & Analytics
Third-Party API Integration (e.g., Slack, Email, Cloud Storage)
Preferred Tech Stack: PHP/Laravel, Python/Django, or MERN Stack (open to suggestions).
