Add customer VAT on PrestaShop invoices

If we want to show the customer's VAT on PrestaShop invoices as in the following image, we only have to modify 2 files.

The first file to modify will be pdf/invoice.address-tab.tpl where we will add this line that will show the customer's VAT:

{if $vat}VAT: {$vat}{/if}

Leaving the file like this:

<table id="addresses-tab" cellspacing="0" cellpadding="0">

<tr>

<td width="50%">{if $delivery_address}{l s='Delivery Address' d='Shop.Pdf' pdf='true'} 

{$delivery_address}

{/if}

</td>

<td width="50%">{l s='Billing Address' d='Shop.Pdf' pdf='true'} 

{$invoice_address} 

{if $vat}VAT: {$vat}{/if}

</td>

</tr>

</table>

The other file to modify is the classes/pdf/HTMLTemplateInvoice.php, but we will create an override of the file by creating it in overrides/classes/HTMLTemplateInvoice.php

The line that we will add will be this

'vat' => ($invoice_address->vat_number != null ? $invoice_address->vat_number : $delivery_address->vat_number),

And the file would look like this:

<?php
