# Invoice Update - Agent User Details

## Overview
Updated the invoice PDF template to display **Agent User** details instead of **Consultant** (creator) details.

## Changes Made

### File Modified
**`resources/views/vouchers/invoice.blade.php`**

### Before (Line 151-154)
```blade
<tr>
    <td>Consultant</td>
    <td>{{ $booking->creator ? $booking->creator->emp_name : 'N/A' }}</td>
</tr>
```

### After (Line 151-154)
```blade
<tr>
    <td>Agent User</td>
    <td>{{ $booking->agentUser ? $booking->agentUser->name : 'N/A' }}</td>
</tr>
```

---

## What Changed

| Field | Before | After |
|-------|--------|-------|
| **Label** | Consultant | Agent User |
| **Data Source** | `$booking->creator->emp_name` | `$booking->agentUser->name` |
| **Relationship** | User (creator) | AgentUser |

---

## Invoice Information Section

The invoice now displays the following information in order:

1. **Bill To** - Agent Name (`$agent->agent_name`)
2. **Agent User** - Agent User Name (`$booking->agentUser->name`) ✨ **NEW**
3. **Company** - Company Name
4. **Branch** - Ajman
5. **Guest Name** - Guest Name (uppercase)
6. **Booking Reference** - Supplier Booking Reference (if exists)

---

## Data Flow

### Backend (VoucherController.php)
```php
$booking = Booking::with([
    'guest',
    'agent',
    'agentUser',  // ✅ Already loaded
    'supplier',
    'hotelBookings.hotel',
    'hotelBookings.roomType',
    'hotelBookings.mealPlan',
    'carBookings',
    'serviceBookings'
])->findOrFail($bookingId);
```

### Frontend (Invoice Template)
```blade
<tr>
    <td>Agent User</td>
    <td>{{ $booking->agentUser ? $booking->agentUser->name : 'N/A' }}</td>
</tr>
```

---

## AgentUser Model Structure

**File:** `app/Models/AgentUser.php`

**Fields:**
- `id` - Primary Key
- `agent_id` - Foreign Key to agents table
- `name` - Agent User Name ✅ **Used in Invoice**
- `phone` - Phone Number
- `email` - Email Address
- `created_at` - Timestamp
- `updated_at` - Timestamp
- `deleted_at` - Soft Delete Timestamp

---

## Booking Model Relationship

**File:** `app/Models/Booking.php`

```php
/**
 * Get the agent user associated with the booking
 */
public function agentUser()
{
    return $this->belongsTo(AgentUser::class);
}
```

---

## Why This Change?

### Previous Issue
- Invoice showed "Consultant" which was the **internal user** who created the booking
- This was confusing for agents/clients receiving the invoice

### Solution
- Invoice now shows "Agent User" which is the **agent's contact person**
- This is more relevant for the agent receiving the invoice
- Provides better context for who to contact at the agent's company

---

## Benefits

1. ✅ **More Relevant Information** - Shows the agent's contact person instead of internal staff
2. ✅ **Better Communication** - Agents know who the booking is associated with
3. ✅ **Clearer Context** - "Agent User" is more descriptive than "Consultant"
4. ✅ **Consistent Data** - Uses the same agent user selected during booking creation

---

## Testing Checklist

- [ ] Generate invoice for booking with agent user assigned
- [ ] Verify "Agent User" label appears instead of "Consultant"
- [ ] Verify agent user name displays correctly
- [ ] Generate invoice for booking without agent user (should show "N/A")
- [ ] Verify all other invoice fields remain unchanged
- [ ] Test with different bookings (hotel, car, service)
- [ ] Verify PDF formatting is correct
