In Portugal, all invoices must be issued by software certified by Finanças (Portuguese Tax Center). The most used e-commerce platforms (Woocommerce, Prestashop, Shopify) have their own invoice management, however the documents issued through these platforms are not certified by the Portuguese tax authorities. You must therefore connect your e-commerce site to your certified invoicing software so that for each order an invoice recognized by the Portuguese state is issued in your invoicing software.
