Como informar múltiplas formas de pagamento?

[marivaldojr]

Talvez o médodo setPaymentMethod pudesse ser assim:

/**
 * Set the invoice payment method
 *
 * @param  array|string  $paymentMethod
 *
 * @return InvoiceBuilder
 */
public function setPaymentMethod(array|string $paymentMethods): InvoiceBuilder
{
    $paymentMethods = is_array($paymentMethods) ? $paymentMethods : [$paymentMethods];

    $this->model->paymentMethod = $paymentMethod;
    
    return $this;
}
