What is SIGN PT?
Section titled “What is SIGN PT?”Portugal requires fiscally relevant documents — invoices, receipts, and related records — to be created with certified invoicing software and secured against tampering. SIGN PT is a platform-independent, software-only RESTful API that lets your ERP, POS, or invoicing system create, sign, and report compliant documents without dedicated hardware.
In practice, SIGN PT helps you:
- Digitally sign and chain invoices, receipts, and other fiscal documents,
- Register document series with the AT and generate the corresponding ATCUD,
- Produce a QR code on every fiscally relevant document,
- Report invoicing data to the AT — in real time via Web Services or through monthly SAF-T (PT) XML exports,
- and, from 2027 onward, secure PDF invoices with a qualified electronic signature (QES).
