e-Fatura and Portal das Finanças: notifications for invoice issuance and validation

EIn Portugal, all invoices must be reported to the Tax Authority (AT) via e-Fatura on Portal das Finanças. Businesses, freelancers and any economic entity use certified systems (PHC, Primavera, Sage, Moloni, Vendus, InvoiceXpress) that issue invoices with QR-code and ATCUD. 4notify activates deadline reminders, validations and rejection notifications for accountants and finance managers.
Context

Missing the SAF-T reporting deadline (5th of following month) brings a €200-€10,000 fine per taxpayer. For accountants with 100+ clients, manual tracking is unfeasible.

Legal framework
Decreto-Lei n.º 28/2019 — e-Fatura obrigatória

All invoices must carry QR-code + ATCUD since 2023.

Portaria 195/2020 — SAF-T mensal

SAF-T submission to AT by 5th of following month.
