## Why use FNE Client?

### Simplicity

```php
use Neocode\FNE\Facades\FNE;

// Certify an invoice in just a few lines
$result = FNE::invoice()->sign([
    'invoiceType' => InvoiceType::SALE->value,
    'paymentMethod' => PaymentMethod::MOBILE_MONEY->value,
    // ...
]);
```

### Flexibility

The SDK supports custom mapping to transform your ERP data structures to FNE format:

```php
// config/fne.php
'mapping' => [
    'invoice' => [
        'clientCompanyName' => 'customer.company_name',
        'clientPhone' => 'customer.phone',
    ],
],
```

### Model Integration

Use the provided traits to directly integrate certification into your models:

```php
use Neocode\FNE\Concerns\CertifiableInvoice;

class Invoice extends Model
{
    use CertifiableInvoice;
}

// Certify directly from the model
$invoice->certify();
```
