SAF-T (Standard Audit File for Tax) is an XML file with a standardised structure containing a company's accounting, invoicing and inventory data, required by the Portuguese Tax Authority. Every company with organised accounting must generate an invoicing SAF-T monthly (since 2013) and an accounting SAF-T annually, as well as provide it on audit when requested.
SAF-T has multiple versions (SAF-T PT for Portugal, with Portuguese specifics) and multiple types (Invoicing, Accounting, Integrated). Errors in SAF-T — invalid codes, inconsistencies between documents, omissions — result in fines and requests for clarification that consume weeks of administrative time. Software certified by the Tax Authority generates correct SAF-T by construction.
The MULTI ERP by INFOS is software certified by the Tax Authority, with SAF-T generated automatically in line with the latest specifications. Regulatory changes (and there are many in Portugal) arrive by update, without reimplementation projects. SAF-T is integrated with electronic invoicing, QR Code and ATCUD.
