Hi @trollytownstudio,

Try this code snippet:

/**
 * PDF Invoices & Packing Slips for WooCommerce:
 * Customize the VAT label on the PDF documents.
 */
add_filter( 'wpo_wcpdf_woocommerce_totals',  function( $totals, $order, $document_type ) {
	$totals['tax']['label'] = __( 'BTW', 'woocommerce' );
	return $totals;
}, 10, 3 );

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