## ⚠️ What Needs Completion (5%)

### Critical: Integrate Subscription Flow into Booking Process

**File to Update**: `BookingResourceController.php` → `processPublicBooking()` method

**What's Needed** (⏱️ 30-45 minutes):

```php
// In processPublicBooking() method:

if ($request->input('booking_type') === 'subscription') {
    // Get selected package
    $packageId = $request->input('subscription_package_id');
    $package = BookingSubscriptionPackage::findOrFail($packageId);

    // Create or get customer
    $customer = Customer::firstOrCreate([...]);

    // Use Stripe service to create subscription
    $stripeService = new StripePaymentService($website);
    $result = $stripeService->createRecurringSubscription(
        $customer,
        $package,
        $resource,
        $request->input('use_trial', false)
    );

    if ($result['success']) {
        // Redirect to Stripe checkout for payment setup
        return redirect($result['stripe_subscription']->latest_invoice->hosted_invoice_url);
    }
}
```

### Nice-to-Have: Credit Tracking

**Files to Update**:
- `CustomerSubscription` model: Add `useCredit()` and `hasCreditsAvailable()` methods
- Booking creation: Check/deduct credits before confirming

**What's Needed** (⏱️ 30 minutes):

```php
// In CustomerSubscription model:
public function useCredit()
{
    if ($this->credits_remaining > 0) {
        $this->decrement('credits_remaining');
        $this->increment('bookings_this_period');
        return true;
    }
    return false;
}

public function hasCreditsAvailable()
{
    // Check if unlimited or has credits
    return $this->package->max_bookings_per_period === null
        || $this->credits_remaining > 0;
}
```

## 🧪 Testing Guide

### Test Stripe Subscription (Test Mode)

**Prerequisites:**
1. Enable Stripe in payment settings
2. Use test keys (pk_test_xxx / sk_test_xxx)
3. Create booking resource with payment_mode = 'subscription'
4. Add at least one subscription package

**Test Steps:**

1. **Visit booking page:**
   ```
   https://{subdomain}.neosolvix.test/book/{resource-slug}
   ```

2. **Select subscription package**
   - Should see package cards with pricing
   - Click "Select Package"

3. **Complete booking form**
   - Fill customer details
   - Submit

4. **Payment (After integration complete):**
   - Redirected to Stripe
   - Enter test card: `4242 4242 4242 4242`
   - Confirm subscription

5. **Verify:**
   ```
   Admin → Subscriptions → Should see new subscription
   Status: active or trialing
   Credits: Allocated from package
   ```

6. **Test Webhook:**
   - Use Stripe CLI: `stripe listen --forward-to https://yourdomain.test/api/webhooks/stripe/{website_id}`
   - Trigger event: `stripe trigger invoice.payment_succeeded`
   - Check logs: Credits should reset

### Test Cards (Stripe):
- **Success**: 4242 4242 4242 4242
- **Decline**: 4000 0000 0000 0002
- **Auth Required**: 4000 0025 0000 3155
