Customize the text "Total" in WooCommerce checkout page

OPTION 1 (best option)

Overriding the woocommerce checkout/review-order.php template.

You need first (if not done) to copy the templates sub folder located in in woocommerce plugin folder to your active child theme (or theme) folde, and rename it woocommerce.

Once done in your active theme go to woocommerce > checkout, and open/editreview-order.php template file.

At the end of this template you have this:

        <?php do_action( 'woocommerce_review_order_before_order_total' ); ?>        <tr class="order-total">            <th><?php _e( 'Total', 'woocommerce' ); ?></th>            <td><?php wc_cart_totals_order_total_html(); ?></td>        </tr>        <?php do_action( 'woocommerce_review_order_after_order_total' ); ?>    </tfoot></table>

So you will change:

<th><?php _e( 'Total', 'woocommerce' ); ?></th>

To:

<th><?php _e( 'Total inkl. vat', 'woocommerce' ); ?></th>

Now you can save, you are done…

OPTION 2 (Not ideal, see below)

You could use wordpress gettex() native function for that purpose, this way:

add_filter('gettext', 'wc_renaming_checkout_total', 20, 3);function wc_renaming_checkout_total( $translated_text, $untranslated_text, $domain ) {    if( !is_admin() && is_checkout ) {        if( $untranslated_text == 'Total' )            $translated_text = __( 'Total inkl. vat','theme_slug_domain' );    }    return $translated_text;}

This code goes in function.php file of your active child theme (or theme) or also in any plugin file.

But you will get 2 customized texts in the prices table, because there is 2 "Total" texts (once in the first line after 'Products') and one time at the end…

This code is tested and works.
