### 10. Routes Configuration (Priority: HIGH)

Add to `routes/web.php`:

```php
// Super Admin Routes
Route::middleware(['auth', 'isSuperAdmin'])->prefix('superadmin')->name('superadmin.')->group(function () {
    // Plans Management
    Route::resource('plans', PlanController::class);
    Route::post('plans/{plan}/toggle-status', [PlanController::class, 'toggleStatus'])->name('plans.toggle-status');
    
    // Razorpay Settings
    Route::get('razorpay/settings', [RazorpaySettingController::class, 'index'])->name('razorpay.settings');
    Route::put('razorpay/settings', [RazorpaySettingController::class, 'update'])->name('razorpay.update');
    Route::post('razorpay/test', [RazorpaySettingController::class, 'test'])->name('razorpay.test');
    
    // Subscription Management
    Route::get('subscriptions', [SubscriptionManagementController::class, 'index'])->name('subscriptions.index');
    Route::get('subscriptions/create', [SubscriptionManagementController::class, 'create'])->name('subscriptions.create');
    Route::post('subscriptions', [SubscriptionManagementController::class, 'store'])->name('subscriptions.store');
    Route::get('subscriptions/{subscription}', [SubscriptionManagementController::class, 'show'])->name('subscriptions.show');
    Route::post('subscriptions/{subscription}/change-plan', [SubscriptionManagementController::class, 'changePlan'])->name('subscriptions.change-plan');
    Route::post('subscriptions/{subscription}/cancel', [SubscriptionManagementController::class, 'cancel'])->name('subscriptions.cancel');
    Route::post('subscriptions/{subscription}/cancel-immediately', [SubscriptionManagementController::class, 'cancelImmediately'])->name('subscriptions.cancel-immediately');
    Route::post('subscriptions/{subscription}/resume', [SubscriptionManagementController::class, 'resume'])->name('subscriptions.resume');
    Route::get('subscriptions-transactions', [SubscriptionManagementController::class, 'transactions'])->name('subscriptions.transactions');
    Route::get('subscriptions-analytics', [SubscriptionManagementController::class, 'analytics'])->name('subscriptions.analytics');
});

// User Subscription Routes
Route::middleware(['auth'])->group(function () {
    Route::get('subscription/plans', [SubscriptionController::class, 'index'])->name('subscription.plans');
    Route::get('subscription/checkout/{plan}', [SubscriptionController::class, 'checkout'])->name('subscription.checkout');
    Route::post('subscription/process-payment', [SubscriptionController::class, 'processPayment'])->name('subscription.process-payment');
    Route::get('subscription/success', [SubscriptionController::class, 'success'])->name('subscription.success');
    Route::get('subscription/cancel', [SubscriptionController::class, 'cancel'])->name('subscription.cancel');
    
    Route::middleware(['subscription'])->group(function () {
        Route::get('subscription/manage', [SubscriptionController::class, 'manage'])->name('subscription.manage');
        Route::post('subscription/change-plan/{plan}', [SubscriptionController::class, 'changePlan'])->name('subscription.change-plan');

        Route::get('subscription/invoices/{invoice}', [InvoiceController::class, 'show'])->name('subscription.invoices.show');
        Route::get('subscription/invoices/{invoice}/download', [InvoiceController::class, 'download'])->name('subscription.invoices.download');
    });
});

// Razorpay Webhook (no auth required)
Route::post('webhooks/razorpay', [WebhookController::class, 'handle'])->name('webhooks.razorpay');
```

### 11. Invoice PDF Generation (Priority: MEDIUM)

Install package:
```bash
composer require barryvdh/laravel-dompdf
```

Create `InvoiceService` in `app/Services/`:
- Generate PDF invoices
- Email invoices to users
- Store invoices in storage

### 12. Feature Access Control Integration (Priority: HIGH)

Apply middleware to existing routes that need subscription checks:

```php
// Example: Protect Ads Manager
Route::middleware(['subscription', 'feature:has_ads_manager'])->group(function () {
    Route::resource('ads', AdController::class);
});

// Example: Protect Analytics
Route::middleware(['subscription', 'feature:has_analytics'])->group(function () {
    Route::get('analytics', [AnalyticsController::class, 'index']);
});

// Example: Protect Competitor Insights
Route::middleware(['subscription', 'feature:has_competitor_insights'])->group(function () {
    Route::resource('competitors', CompetitorController::class);
});
```

### 13. Usage Tracking Implementation (Priority: MEDIUM)

Add usage tracking to relevant controllers:

```php
// Example: Track content idea creation
public function store(Request $request)
{
    $user = auth()->user();
    
    // Check if user can create more content ideas
    if (!$user->subscription->canUseFeature('max_content_ideas_per_month')) {
        return redirect()->back()->with('error', 'You have reached your monthly content ideas limit.');
    }
    
    // Create content idea
    $contentIdea = ContentIdea::create($request->all());
    
    // Increment usage
    $user->subscription->incrementUsage('max_content_ideas_per_month');
    
    return redirect()->route('content-ideas.index');
}
```

### 14. Sidebar Updates (Priority: MEDIUM)

Update sidebars to show subscription-related links:

#### Super Admin Sidebar
Add to `resources/views/components/superadmin-sidebar.blade.php`:
```blade
<li>
    <a href="{{ route('superadmin.plans.index') }}">
        <i class="fas fa-tags"></i> Subscription Plans
    </a>
</li>
<li>
    <a href="{{ route('superadmin.subscriptions.index') }}">
        <i class="fas fa-credit-card"></i> Subscriptions
    </a>
</li>
<li>
    <a href="{{ route('superadmin.subscriptions.analytics') }}">
        <i class="fas fa-chart-line"></i> Subscription Analytics
    </a>
</li>
<li>
    <a href="{{ route('superadmin.razorpay.settings') }}">
        <i class="fas fa-cog"></i> Razorpay Settings
    </a>
</li>
```

#### User Sidebars (Brand, Creator, Agency)
Add subscription management link:
```blade
<li>
    <a href="{{ route('subscription.manage') }}">
        <i class="fas fa-crown"></i> My Subscription
    </a>
</li>
```

### 15. Notifications & Emails (Priority: LOW)

Create notification classes:
- `SubscriptionCreated`
- `SubscriptionRenewed`
- `SubscriptionCancelled`
- `SubscriptionExpiring` (7 days before expiry)
- `PaymentFailed`
- `InvoiceGenerated`

### 16. Testing (Priority: HIGH)

Create tests in `tests/Feature/`:
- `SubscriptionFlowTest.php` - Test complete subscription flow
- `PaymentProcessingTest.php` - Test payment processing
- `FeatureAccessTest.php` - Test feature access control
- `UsageLimitTest.php` - Test usage limits
- `WebhookHandlingTest.php` - Test webhook processing

---

## 📦 Required Packages

Install these packages:

```bash
composer require razorpay/razorpay
composer require barryvdh/laravel-dompdf
```

---

## 🔧 Configuration Steps

1. **Run Migrations**
```bash
php artisan migrate
php artisan db:seed --class=SubscriptionPlansSeeder
```

2. **Configure Razorpay**
- Login to Super Admin panel
- Navigate to Razorpay Settings
- Enter API Key and Secret
- Test connection
- Activate Razorpay

3. **Set up Webhook**
- In Razorpay Dashboard, configure webhook URL: `https://yourdomain.com/webhooks/razorpay`
- Add webhook secret to Razorpay settings

---

## 🎯 Implementation Priority

1. **HIGH Priority** (Complete First)
   - User-facing subscription controllers
   - Pricing page and checkout flow
   - Payment processing
   - Webhook handler
   - Routes configuration

2. **MEDIUM Priority** (Complete Second)
   - Super Admin views
   - Invoice PDF generation
   - Usage tracking integration
   - Sidebar updates

3. **LOW Priority** (Complete Last)
   - Email notifications
   - Advanced analytics
   - Automated tests

---

## 📝 Notes

- All monetary values are stored in the plan's currency (INR by default)
- Feature limits: `-1` means unlimited
- Subscription statuses: `active`, `trialing`, `past_due`, `cancelled`, `expired`, `incomplete`
- Super Admin always bypasses subscription checks
- Free plans don't require payment processing

---

## 🔐 Security Considerations

- Razorpay credentials are encrypted in database
- Webhook signatures must be verified
- Payment processing uses HTTPS only
- Sensitive data is never logged
- Rate limiting on payment endpoints

---

## 📊 Analytics & Reporting

Super Admin can view:
- Monthly Recurring Revenue (MRR)
- Annual Recurring Revenue (ARR)
- Churn rate
- Revenue by plan
- Active subscriptions count
- Trial conversion rate
- Payment success/failure rates

---

## 🚀 Next Steps

1. Create user-facing subscription controllers
2. Build pricing page with Razorpay integration
3. Implement webhook handler
4. Create Super Admin views
5. Add routes configuration
6. Test complete flow
7. Deploy and configure Razorpay in production
