YITH WooCommerce PDF Invoices & Packing Slips allows you to automatically generate the invoice in PDF format for each registered order in your shop.
The combined use with YITH Point of Sale for WooCommerce allows showing the fields (VAT and SSN and fields related to the Italian Electronic Invoicing) added by the PDF Invoices plugin.
When creating a new customer profile or editing an existing one, YITH PDF Invoices fields will show in the form.
Additional fields will show when using Electronic Invoicing for Italian customers.
