The WooCommerce PDF Invoice plugin allows you to create both standard and pro forma invoices. Invoices and packing slips can be printed using this WooCommerce plugin for PDF invoices. Whenever a new order is placed, WooCommerce sends an invoice as a PDF attachment to the regular email.
There is no limit to how you can modify these invoices and they work with taxes as well. Also, this WooCommerce PDF invoice plugin has a smart numbering system that prevents duplicate invoice numbers and most gaps in the numbering sequence. In addition, you can choose whether or not to send bills by email and whether or not to display the product ID, category, and short description.
