# 2. Build Your Catalog

Your **catalog** is what you sell. In PeakCommerce it has three layers: **products**, the **plans** that package them, and the **charges** that price those plans. With your billing system connected, these sync in automatically — so building your catalog is mostly about **organizing what synced into something customers can buy**.

**Products, plans, and charges**

* **Products** are the things you offer.
* **Plans** package a product into a sellable tier — for example Free, Premium, and Ultimate.
* **Charges** define how a plan is priced — recurring, usage-based, or one-time.

Review these under **Commerce → Product Catalog**.

**Assemble a product set**

A **product set** is the purchasable grouping a customer actually chooses from — a base plan, its add-ons, and options, presented together. A journey sells a product set, so this is the bridge between your catalog and your storefront.

1. Go to **Commerce → Product Sets** and create a set.
2. Add your base plans and any add-ons or options.
3. Save. Your set is now ready for a journey to sell.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.peakcommerce.com/product/getting-started/setup/2.-build-your-catalog.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
