Add string after the 'total' label in invoice

Hi! You can do this by filtering the totals, add the following code to your theme functions / functions.php (read this if you haven’t edited that file before).

add_filter( 'wpo_wcpdf_woocommerce_totals', 'wpo_wcpdf_total_label' );
function wpo_wcpdf_total_label ( $totals ) {
    if ( isset($totals['order_total'])) {
        $totals['order_total']['label'] = $totals['order_total']['label'] . ' Including Tax';
    };
    return $totals;
}

Hope that helps 🙂

You’re welcome! If you can spare a minute or so, I’d really appreciate a review. Thanks in advance and have a fantastic weekend!
