What is the Electronic Invoice (NF-e) in Curitiba and what is it for? What is its history? Does it have advantages? Where can I issue it? This topic has raised a lot of questions for our readers. So we've put together the text below explaining everything about it, simply and objectively.

The Invoice is a mandatory tax document for any transaction involving goods or services, and it is used to collect taxes.
The Electronic Invoice (NF-e) is a tax document created to modernize and simplify transactions between interested parties, since it is transmitted over the internet.
This tax document's security system includes the sender's digital signature, which serves as a legal and tax guarantee for the recipient. It also carries an online certificate obtained from Brazilian tax authorities, guaranteeing its authenticity.

The Electronic Invoice (NF-e) project began in Brazil under Constitutional Amendment No. 42, Item XXII, Article 37.
Following this Constitutional Amendment, the project was coordinated by ENCAT (National Meeting of State Tax Administrators and Coordinators) and developed in partnership with the Brazilian Federal Revenue Service, aiming to roll out a national model of this electronic tax document to replace paper invoices.
The State of Paraná joined the Electronic Invoice project in Curitiba through ICMS Protocol 30/07 of 07/17/2007.
