```php
add_filter( 'woocommerce_billing_fields', function ( $fields ) {
    $fields['billing_is_business'] = array(
        'type'     => 'checkbox',
        'label'    => 'Buying for a business?',
        'class'    => array( 'form-row-wide' ),
        'priority' => 25,
    );

    return $fields;
}, 30 );

add_action( 'woocommerce_after_checkout_validation', function ( $data, $errors ) {
    if ( ! empty( $data['billing_is_business'] ) && '' === trim( (string) ( $data['billing_company'] ?? '' ) ) ) {
        $errors->add( 'validation', 'Please enter your company name.' );
    }
}, 10, 2 );

add_action( 'wp_footer', function () {
    if ( ! function_exists( 'is_checkout' ) || ! is_checkout() || is_wc_endpoint_url() ) {
        return;
    }
    ?>
    <script>
    jQuery( function ( $ ) {
        var box = $( '#billing_is_business' );
        var rows = $( '#billing_company_field, #billing_vat_number_field' );
        function toggle() { rows.toggle( box.is( ':checked' ) ); }
        box.on( 'change', toggle );
        toggle();
    } );
    </script>
    <?php
} );
```

## Notes

Also toggles the VAT number field from the "EU VAT Number Field" snippet, and the Company field must be enabled in the Customizer.
