What is a certified invoice?
In Portugal, all invoices and fiscal documents must be issued through invoicing software certified by the Tax Authority.
To be valid, certified invoices must include:
ATCUD code – a unique identifier that ensures traceability
Digital signature – guarantees the authenticity and compliance of the invoice
Without these elements, the invoice is considered invalid and non-compliant, which can lead to:
Fines and/or audits by the Tax Authority
Problems claiming VAT or business expenses
Increased risk of fraud or tax errors
What are the types of invoices and fiscal documents?
The Portuguese Tax Authority (AT) requires that all relevant fiscal documents you issue are submitted. These documents validate transactions, support tax obligations, and ensure compliance.
Depending on your activity, you may need to issue and report:
Invoices – the standard document for most sales
Receipts – proof of payment
Invoice-Receipts – commonly used by freelancers
Credit Notes – to correct or cancel previously issued invoices
What are SAF-T files?
Another important requirement is the SAF-T file (Standard Audit File for Tax). This file contains detailed records of your accounting and invoicing.
It is generated in .xml format by certified software
It is submitted to the Portuguese Tax Authority (AT) for verification and cross-checking
It must be kept for 10 years
Rauva automatically generates and stores your SAF-T files, so you’re always fully compliant.
