You're actually very close to having a complete HR/Payroll module.

You already have:

✅ Employee Management
✅ Departments
✅ Shifts
✅ Department Schedule Planner
✅ Attendance System
✅ Salary Settings
✅ Payroll Generation

The next modules I would build are:

### 1. Payslip Module (Next Priority)

After payroll is generated, HR should be able to click:

```
Payroll
 ├── Generate Payroll
 ├── View Payroll
 └── Print Payslip
```

Each employee gets:

```text
--------------------------------
BEST WESTERN PLUS
SALARY SLIP

Employee: John Doe
Department: Front Office

Period:
June 2026

Days Worked: 26
Hours Worked: 208

Gross Salary:
₦120,000

Tax:
₦6,000

Pension:
₦4,800

Net Salary:
₦109,200

Authorized By:
HR Department
--------------------------------
```

Tables:

```sql
payroll_details
```

already contains everything needed.

---

### 2. Payroll Approval Workflow

Before salaries are paid:

```text
Draft
↓
Generated
↓
HR Approved
↓
GM Approved
↓
Paid
```

Add:

```sql
ALTER TABLE payroll_details
ADD payroll_status VARCHAR(30)
DEFAULT 'Draft';
```

Status:

```text
Draft
Approved
Paid
```

---

### 3. Leave Management

Tables:

```sql
leave_types
```

```sql
id
name
days_allowed
```

Examples:

```text
Annual Leave
Sick Leave
Compassionate Leave
Maternity Leave
```

And:

```sql
employee_leave
```

```sql
id
employee_id
leave_type_id
start_date
end_date
reason
status
```

This becomes your HR leave portal.

---

### 4. Overtime Management

You already have:

```text
overtime_rate
```

inside:

```sql
employee_salary
```

but payroll is not yet using it.

Add:

```sql
overtime_requests
```

```sql
id
employee_id
work_date
hours
approved_by
status
```

Payroll automatically adds:

```php
$overtimePay =
$overtimeHours *
$overtime_rate;
```

to gross salary.

---

### 5. Holiday Calendar

Create:

```sql
holidays
```

```sql
id
holiday_name
holiday_date
```

Examples:

```text
New Year
Workers Day
Democracy Day
Christmas
```

The scheduler highlights holidays.

---

### 6. Staff Loans & Salary Advances

Very useful in hotels.

Table:

```sql
employee_loans
```

```sql
id
employee_id
amount
balance
monthly_deduction
status
```

Payroll automatically deducts:

```php
loan deduction
```

from net salary.

---

### 7. Payroll Export to Excel

Button:

```text
Export Payroll
```

Exports:

```text
Employee
Department
Gross
Tax
Pension
Net
```

to Excel for accounting.

---

### 8. Employee Documents

Store:

```text
CV
Offer Letter
NIN
Passport
Certificates
Contract
```

Table:

```sql
employee_documents
```

```sql
id
employee_id
document_name
file_path
```

Upload directly from employee profile.

---

### 9. Employee Dashboard

When staff login:

```text
My Schedule
My Attendance
My Leave
My Payslips
My Profile
```

No HR access required.

---

### 10. HR Dashboard (Recommended Next)

Dashboard cards:

```text
Total Employees
Present Today
Absent Today
On Leave
Payroll This Month
Departments
```

Charts:

```text
Attendance Trend
Payroll Trend
Department Headcount
```

### My recommended build order

1. Payslip Printing
2. Payroll Approval
3. Leave Management
4. Overtime Management
5. Payroll Excel Export
6. Employee Dashboard
7. HR Dashboard

The **Payslip module** is the logical next step because your payroll engine is already generating the salary figures. Once payslips are available, HR can immediately start using the system for actual monthly salary processing.
