Requirements for certify calculation for goods transactions

### Introduction

The connector certification requirements for services calculations are designed so that the end-user 

 has a simple implementation process. 

 There are options to obtain certification on sales and purchase transactions. 

The partner will need to define if they desire to implement one or both transaction types. 

 Below are the minimum scenarios necessary for certification.

### Premises

The partner can be certified at any time, but will only be considered "Launched" to the market, after two customers in production using the connector. 

 The partner will be responsible for support customers in production and give the maintenance of the developed connector.

 The partner will be responsible for providing training and a guide to support customers. 

 To present an SLA (Service Level Agreement)plan. 

 Present a schedule detailing development times, unit tests, and integration tests.

We inform the importance of our partners complying with the rules and determinations of the General Data Protection Law -LGPD (Law No. 13,709), not disclosing or exposing customer data.
