## 🎯 Usage Examples

### Check Subscription Status
```php
$organization = auth()->user()->organization;

// Check if has active subscription
if ($organization->hasActiveSubscription()) {
    // Allow access
}

// Check if on trial
if ($organization->onTrial()) {
    $daysLeft = $organization->subscription->trialDaysRemaining();
    // Show trial banner
}

// Get current plan
$plan = $organization->currentPlan();
```

### Enforce Quotas
```php
$usageService = app(UsageTrackingService::class);
$organization = auth()->user()->organization;

// Check if can add employee
if ($usageService->canAdd($organization, 'employees')) {
    Employee::create([...]);
} else {
    // Show upgrade message
}

// Get usage summary
$usage = $usageService->getUsageSummary($organization);
// Returns: ['employees' => ['current' => 6, 'limit' => 50, 'percentage' => 12], ...]
```

### Process Subscription Changes
```php
$subscriptionService = app(SubscriptionService::class);

// Create subscription with trial
$subscription = $subscriptionService->createSubscription(
    $organization,
    $plan,
    'monthly',
    true // with trial
);

// Convert trial to paid
$subscription = $subscriptionService->convertTrialToPaid($subscription);

// Upgrade plan
$subscription = $subscriptionService->changePlan($subscription, $newPlan, true);

// Cancel subscription
$subscription = $subscriptionService->cancelSubscription($subscription);

// Extend trial (admin only)
$subscription = $subscriptionService->extendTrial($subscription, 7);
```

### Generate and Process Invoices
```php
$billingService = app(BillingService::class);

// Generate invoice
$invoice = $billingService->generateSubscriptionInvoice($subscription);

// Process payment (called automatically by M-Pesa callback)
$billingService->processPayment($invoice, $payment);

// Get billing summary
$summary = $billingService->getBillingSummary($organization);
// Returns: ['total_paid' => 0, 'total_pending' => 29900, ...]
```

### Protect Routes
```php
// Require active subscription
Route::middleware(['auth', 'subscription'])->group(function () {
    Route::get('/employees', [EmployeeController::class, 'index']);
});

// Require subscription + quota check
Route::middleware(['auth', 'subscription', 'quota:employees'])->group(function () {
    Route::post('/employees', [EmployeeController::class, 'store']);
});
