Predefined Filters for WooCommerce Invoices, Packing Slips and Credit Notes

In WooCommerce, predefined filters allow store owners to customize and extend the functionality of their order documents, such as invoices, packing slips, and credit notes. These filters enable businesses to customize documents according to their precise requirements to increase efficiency and customer satisfaction.
