This initiative will broaden reporting requirements beyond just invoices to encompass detailed accounting data such as: the Chart of accounts, accounting journals and transactions, VAT categories, master data for suppliers and customers, and the article (product) catalogue.<\/p><h3><strong>QES<\/strong><\/h3><p>A Qualified Electronic Signature (QES) is a legally recognised digital signature that offers a high level of security and authenticity, created according to Regulation (EU) No. 910\/2014 (eIDAS) by a qualified trust service provider. These providers are certified and possess the necessary technology to deliver secure electronic identification services, including electronic signatures. Beginning on January 1, 2027, PDF invoices are required to incorporate a QES to meet invoicing standards, so businesses should implement these signatures to ensure compliance with the law and improve the security of their digital transactions.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-4f42043 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"4f42043\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-5dae3bb\" data-id=\"5dae3bb\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-c482a63 elementor-widget elementor-widget-heading\" data-id=\"c482a63\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">The SAP solution<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-9832987 elementor-widget elementor-widget-text-editor\" data-id=\"9832987\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>The SAP solution is a centralized framework that manages the ATCUD codes and document series. It offers two solutions, a manual and an automatic solution. A new Number Range with the new Series definition has to be created based on the restriction of the Portuguese tax authorities to make sure that these codes are unique.<\/p><p>The manual solution requires that the Number ranges\/series need to be entered on the Portuguese tax authority portal manually. The system will then return the updated validation codes.<\/p><p>In the automatic process, the SAP solution communicates the Number ranges\/series to the tax authority. Afterwards, it stores the returned validation code automatically. This automated communication is done by using a web service for example, by integrating SAP Cloud Integration (CPI) onto your SAP system.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-a4a2c9f elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"a4a2c9f\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-09e9fe0\" data-id=\"09e9fe0\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-1d39f75 elementor-widget elementor-widget-heading\" data-id=\"1d39f75\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Why you should comply with these new reporting requirements<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-be31de3 elementor-widget elementor-widget-text-editor\" data-id=\"be31de3\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>The most important reason to comply with the new Portuguese reporting regulations is to avoid paying penalties, as non-compliance will result in a fine.
