Create an hr app for a Django-based ISP system (Optinet Global Links) that includes full employee management, user invitations, department-based permissions, and a payroll engine with support for deductions, bonuses, and payslip generation.

🧑‍💼 1. Employee Management (CRUD)
Employee model should include:

Full name, email, phone

ID/Passport number

KRA PIN

Date of birth

Hire date

Department (ForeignKey)

Designation

Basic salary

Employment status (active/terminated/on leave)

Admin users can:

Create, edit, delete, and view employee profiles

Upload optional documents (ID, contract, CV)

Send account invitations via email to employees so they can register/log in as staff (linked to Django User model).

🏢 2. Departments & Role Permissions
Departments are:

Network

Field Technicians

Billing

Customer Support

Admin

HR

Each department can be linked to a user group with Django permissions (e.g., technicians cannot see invoices, billing cannot access tickets).

When a department is assigned to an employee, that employee inherits the group permissions.

💸 3. Bonuses & Deductions
Bonus model:

Employee (FK)

Amount

Reason

Date

Deduction model:

Employee (FK)

Amount

Reason

Date

Each bonus or deduction entry should be logged and viewable in employee profile or payroll records.

🧾 4. Payroll Generator
Generate monthly payslips using:

ini
Copy
Edit
payslip_amount = basic_salary + total_bonuses - total_deductions
Allow admin to select:

Payroll month/year

Filter employees by department/status

Auto-generate payroll:

Show summary table with all employee payouts

Allow download/export as PDF or Excel

Generate individual payslips

📄 5. Payslip Management
Generate per-employee payslip:

Employee info

List of bonuses and deductions

Final net pay

Option to download as PDF

Employee can view/download their payslips from their dashboard.
