 * Hi [@konnox](https://wordpress.org/support/users/konnox/),
 * If you want to add the extra custom fields into the invoice then you will need
   to write a custom code for this. There is a filter “wcdn_order_info_fields” present
   in the “print-content.php” file of our plugin. You can use this filter and write
   a callback function to add the extra custom fields.
 * The print-content.php file is located at the following path: wp-content\plugins\
   woocommerce-delivery-notes\templates\print-order\print-content.php
 * Please check the same and let us know if you need any help.
 * Regards,
    Komal Maru
