How to add GST columns

Hello @selfhostedlife,

You can add custom fields to your invoices using the template action hooks. See several examples about adding new fields to your invoices here.

Let’s say your custom field is stored with the order meta key custom_field_name, then you could add this field to your invoices using the following code snippet:

add_action( 'wpo_wcpdf_after_billing_address', 'wpo_wcpdf_delivery_date', 10, 2 );
function wpo_wcpdf_delivery_date ($template_type, $order) {
? ? $document = wcpdf_get_document( $template_type, $order );
? ? if ($template_type == 'invoice') {
? ? ? ? ?>
? ? ? ? <tr class="custom-field">
? ? ? ? ? ? <th>Custom Field:</th>
? ? ? ? ? ? <td><?php $document->custom_field('custom_field_name'); ?></td>
? ? ? ? </tr>
? ? ? ? <?php
? ? }
}

If you haven’t worked with code snippets (actions/filters) or functions.php before, read this guide: How to use filters

You can also add any field, without no code, using Premium Templates. This extension includes a customizer that allows you to tailor your PDF documents using product columns, total rows, and custom blocks. In addition, Premium Templates provides two additional templates: Business and Modern.

For your specific case, you only need to add a custom, block this way:

Then, your invoices will display your custom field:

Let me know if you have more questions ??

Thanks for your help, sir.

Hi @selfhostedlife,

Thanks for clarifying. This can be done with the customizer included in Premium Templates. The customizer allows you to add new total rows to your invoices, including the VAT total row:

Then your invoices will display your different VAT rates on your invoices:
