Portugal separates B2G invoice exchange from AT fiscalization, series communication, ATCUD and SAF-T (PT). The applicable duties depend on recipient, software and tax scope. Peppol exchange with scheme 9946 does not replace AT reporting, SAF-T (PT), certified invoicing software, series communication or ATCUD. Dynafis therefore exposes exchange, reporting and fiscalization rails separately.
E-invoicing by country
E-invoicing in Portugal: mandates, formats, sending and receiving
Dynafis combines invoice validation, recipient capability, country profiles and evidence for Portugal. The permitted route is determined per legal entity, transaction and environment; FE-AP is only one part of the overall process.
The profile distinguishes B2B, B2G, B2C and cross-border. Scope also depends on establishment, tax registration, recipient type, public procurement and cross-border context.
Relevant networks and portals include FE-AP, Autoridade Tributária and Peppol. Dynafis validates CIUS-PT, SAF-T (PT) and Peppol BIS Billing 3.0 and the addressing schemes 9946 as separate concerns.

Accounting firms configure Portugal per client and legal entity. Credentials, provider accounts, documents and production approvals never inherit between clients; month-end checks remain traceable per legal entity.

Is e-invoicing mandatory in Portugal?
Portugal separates B2G invoice exchange from AT fiscalization, series communication, ATCUD and SAF-T (PT). The applicable duties depend on recipient, software and tax scope. The exact scope must be assessed for the legal entity and transaction.
Is Peppol sufficient for Portugal?
Not automatically. Peppol may be an exchange rail, but it replaces national clearance, reporting or fiscalization such as FE-AP, Autoridade Tributária and Peppol only when the active country profile explicitly permits it.
What does Dynafis support for Portugal today?
Dynafis includes the country profile and technical rails. Production requires complete legal-entity setup, credentials, connection testing and provider evidence.
