In Brazil, there are two main e-Invoicing models: One is for service invoices and the other isfor goods invoices. Each of them must be reported to separate tax collection authorities. To sign invoices, a certificate from a certification authority authorized by Brazilian Public Key Infrastructure (ICP-Brasil) is required, as well as a preliminary test with the SEFAZ. There are different e-Invoice formats, all in XML,but have different structures depending on the nature of the good to be invoiced:

•  NF-e: for goods
• NFS-e: for services
• CT-e: Waybill for the transportation of goods.
