# Transactions overview

This section describes the transactions and payload models that allows the construction of a connector with AvaTax Brazil for the issuance of service invoices.

It is important to emphasize that, in this module, we assume that the calculation has already been performed previously (either by AvaTax Brazil itself, or with data from the source system), and therefore, the information sent should only have communication purposes with the tax authorities to obtain the electronic invoice for services.

For more information and scenarios, refer to "[Functional Documentation AvaTax Brazil](https://documenter.getpostman.com/view/4090178/UVknuGfm#intro)".
