Intelligent E-Invoicing Solution for Portugal's SAFT-PT Regime
Portugal has been a European e-invoicing pioneer since 2013 with mandatory SAFT-PT reporting. With ATCUD unique document codes, QR codes on all invoices, and certified billing software requirements enforced by the Autoridade Tributária (AT), compliance demands are rigorous. InvoStaq's AI engine audits every invoice inside your ERP — zero errors, zero fines.
Your AI Shield for Portuguese E-Invoicing Compliance
Portugal operates one of Europe's most mature e-invoicing and tax reporting systems. Since 2013, all businesses must submit monthly SAFT-PT (Standard Audit File for Tax — Portuguese version) files to the Autoridade Tributária e Aduaneira (AT). Decree-Law 28/2019 further tightened requirements by mandating the use of certified billing software, QR codes on all invoices, and the ATCUD (Código Único de Documento) — a unique alphanumeric code on every fiscal document. B2G e-invoicing is mandatory through the ESPAP/FE-AP platform, and Portugal fully supports the Peppol network for public procurement.

Mandate Status by Business Sector
Current compliance requirements across B2B, B2G, and B2C transactions.
B2B (Business-to-Business)
B2B e-invoicing reporting has been mandatory in Portugal since 2013 through monthly SAFT-PT file submission to the Autoridade Tributária. All businesses must use AT-certified billing software, generate ATCUD codes, and include QR codes on invoices. Invoice data is communicated electronically to AT in near-real-time or via monthly SAFT-PT exports.
B2G (Business-to-Government)
B2G e-invoicing is mandatory through the ESPAP platform (Entidade de Serviços Partilhados da Administração Pública) and the FE-AP (Faturação Eletrónica da Administração Pública) system. Suppliers to the Portuguese government must submit structured electronic invoices compliant with EU Directive 2014/55/EU via the ESPAP/Peppol network.
B2C (Business-to-Consumer)
Portugal mandates the use of certified billing software for all invoices, including B2C. Every invoice must contain a QR code and ATCUD unique code. Consumer invoices are reported to AT, and consumers can verify their invoices through the e-Fatura portal for personal tax deductions.

SAFT-PT Mandatory Reporting
Monthly SAFT-PT file submission to the Autoridade Tributária becomes mandatory for all Portuguese businesses. Portugal becomes one of the first EU countries with comprehensive digital tax reporting.
Decree-Law 28/2019 Enacted
Decree-Law 28/2019 establishes new requirements for certified billing software, mandates QR codes on all fiscal documents, and introduces the ATCUD unique document code framework.
QR Code on Invoices
All fiscal documents must include a QR code enabling verification by the Autoridade Tributária. The QR code encodes key invoice data for automated compliance checks.
ATCUD Mandatory
The ATCUD (Código Único de Documento) becomes mandatory on all fiscal documents. Each document receives a unique alphanumeric code combining a series validation code from AT with a sequential number.
Enhanced SAFT-PT & Real-Time Reporting
AT enhances SAFT-PT schema requirements and strengthens real-time communication of invoice data. Integration with e-Fatura platform deepened for cross-referencing and fraud detection.
Legal & Regulatory Framework
Portugal's e-invoicing framework is governed by Decree-Law 28/2019, which modernised the country's fiscal document requirements. Portaria 195/2020 defines the technical specifications for the ATCUD code and QR code implementation. The Autoridade Tributária e Aduaneira (AT) publishes binding guidance on SAFT-PT file structure, certified software requirements, and compliance procedures. B2G e-invoicing follows EU Directive 2014/55/EU, implemented via the ESPAP/FE-AP platform.
