There's no need to split out your results so heavily in your controller. Also by doing $invoices[0] you are obviously just getting data from the first result.

Simply pass the invoices variable into the template and loop through it in twig.

//controller
...
return $this->render('InvoicesInvoicesBundle:Invoices:invoicepreview.html.twig', array(
    'invoices' => $invoices
));

{# twig template #}
{% for invoice in invoices %}
    {# render any data you want here with the required html #}
    {{ invoice.companyName }}
    {# ... #}
{% endfor %}
