# Overview

Leverage Stigg's **product catalog** to model your pricing using the building blocks of the Stigg platform:

* **Products** represents a product family or business line that you offer to your customers - products are composed of plans and add-ons.
* **Plans** define how a product is packaged, priced, and made available to customers over a specific billing interval.
* **Add-ons** allow you to offer separately billable functionality that extends the capabilities of existing plans.
* **Features** are monetizable units of functionality in your product that can be configured and packaged in different ways. These configured feature rights are called **entitlements**, which define the specific access a customer has to each feature.
* **Coupons** are discount instruments that can be applied to reduce the billing amount.
* **Credits** are units of value in a custom currency that are granted to customers and deduct as they use metered features.

  Stigg's architecture allows you assign and transfer features to different products, plans an add-ons without requiring any additional engineering resources

## Before we begin

Stigg supports the creation of multiple environments in each account in order to support your existing product development process. Every environment is **isolated** from one another.

Select the environment that will be used for the initial integration of Stigg with your application.

We recommend first integrating Stigg with a **development** or **staging** environment.

<Note>
  When a new environment is created, a default product for that environment will be automatically created. The product name will be the same name as the account name, for example: if your account name is **Acme**, an **Acme** product will automatically be created in every newly created environment.

  You can edit the name of the default product, or even remove it altogether and create a new one.
