This plugin automatically generates PDF invoices, packing slips, and credit notes for WooCommerce orders. It lets you customise templates with your logo, business details, and preferred layout, keeping your documents on brand. Customers can download their invoice directly from the order confirmation email or their account page, while you can print packing slips in bulk for faster order processing.
