# Choose where you want to display your Product Catalogs

There are typically two different data models for attaching spare parts catalogs within a B2B

### Product Category Based Model

Setting up Product Catalogs based on the product category is a great way to utilize built in objects when starting with B2B LWR Digital Experiences.

**Pros**

* No need for Custom object creation

**Considerations**
