## Example in Action

Install Cashier:

```bash
composer require laravel/cashier
```

Set up the `Billable` trait in your `User` model:

```php
namespace App\Models;

use Laravel\Cashier\Billable;

class User extends Authenticatable
{
    use Billable;
}
```

Create a new subscription:

```php
$user = User::find(1);
$user->newSubscription('default', 'price_id')->create($paymentMethod);
```

Handle Stripe webhooks:

```bash
php artisan cashier:webhook
```

Cashier streamlines subscription billing, making it easier to build and manage SaaS applications.
