# Get started

Guide: Communications

Welcome to the *AvaTax for Communications Integration Guide*! If you're supplying communications tax, this guide describes the steps you should follow to integrate basic AvaTax for Communications (AFC) into your billing system.

The sections are broken down into individual milestones in the order they should be completed in your integration, so be sure to complete a milestone before moving on to the next.

For **technology partners**, each milestone includes a Certification Requirements section for you to quickly ascertain what needs to be accomplished in order to earn an Avalara [Communications Tax badge](https://developer.avalara.com/certification/avatax/communication-badge/). The badge requirements are broken down into the following types:

* **Required**: This design element is required in order to become certified.
* **Conditional**: Depending on your use case, this design element may be required.
* **Suggested**: This design element is not required, but we recommend that your UI includes suggested elements.

Note that certification does not entail a code review from Avalara. The requirements are provided to help you create an integration that is straightforward and uncomplicated for your end users and to help ensure that your integration is tax compliant.

For **API customers**, we recommend that you follow this guide when using AvaTax APIs in your own systems.
