E-invoice channels — Portal das Finanças (AT) in Portugal
Every Corp-Merch invoice in Portugal is born electronic, validated against Portal das Finanças (AT) schemas, and ingested by your ERP — zero re-keying, full audit trail.
Portugal — the Portal das Finanças (AT) channel
Portal das Finanças (AT) is Portugal's tax authority — invoices issued by certified billing software must be reported via SAF-T (PT) and Webservice WSE-Faturas in real-time. From 2024 B2G invoices must follow CIUS-PT (Peppol BIS Billing 3.0). Mandatory ATCUD code (Código Único de Documento) and QR code on every invoice, validated via Webservice when issued. Corp-Merch is fully certified to issue invoices on Portal das Finanças (AT); signed XML stored 10 years per local archive law. Our invoice gateway issues, validates and submits in seconds; success/failure event returned to your ERP via REST callback or AS2.
Format, validation and the audit trail
Invoices issued in the country-mandated XML format (Portal das Finanças (AT)), signed with a qualified electronic signature (QES per eIDAS Regulation 910/2014), archived for 10 years. We store the issuance acknowledgement from Portal das Finanças (AT) plus the signed XML and a human-readable PDF — all three available via API. Auditors can pull the full chain for any invoice instantly.
