NF-e
Nota Fiscal Eletrônica
Brazil's electronic invoice standard. NF-e XMLs contain ICMS tax breakdowns, NCM codes, and transport data.
Overview
NF-e (Nota Fiscal Eletrônica) is Brazil's mandatory electronic invoice for goods, introduced in 2008 and governed by SEFAZ (State Treasury Departments). Every goods transaction in Brazil must generate an NF-e XML with a unique 44-digit access key (chave de acesso). The XML contains detailed tax breakdowns including ICMS (state VAT), IPI (federal excise), PIS/COFINS (social contributions), and NCM product classification codes.

Frequently Asked Questions
What is the difference between NF-e and NFC-e?
NF-e is for B2B goods transactions. NFC-e (Nota Fiscal de Consumidor Eletrônica) is the simplified version for B2C retail. InvoSnap supports both formats.
What are NCM codes and does InvoSnap extract them?
NCM (Nomenclatura Comum do Mercosul) codes are 8-digit product classification codes used across Mercosur countries. InvoSnap extracts NCM codes from each line item in the NF-e XML.
How do I validate an NF-e access key?
The 44-digit chave de acesso embeds the CNPJ, series, number, and a check digit. You can validate it at the SEFAZ portal (nfce.sefaz.rs.gov.br or similar). InvoSnap extracts the key but does not validate it.
