# Product Groups

****Marlin GTX**** enables products to be categorised into product groups for classification, reporting and pricing.

**Product Reporting Levels:**

- **Product Departments:** Highest-level summary of stock sales
- **Product Supergroups:** Broad groupings such as manufacturer
- **Product Groups:** Categories of products within a department
- **Individual Products:** Detailed reporting for a single product

[Product groups](/gtx/docs/product-groups#product-groups) define how products are grouped for reporting and inventory.

[Product supergroups](/gtx/docs/product-groups#product-supergroups) sit above product groups and provide broader categorisation.

Each product group belongs to a **[department](/gtx/docs/departments)** and can include defaults for reporting and pricing.

> [Markup Sets](/gtx/docs/price-markups#markup-sets) can be assigned at the product group level for consistent pricing rules.

          Note

          

Product groups are mandatory and **must be assigned to every product**.

## Product Supergroups

Product supergroups define higher-level categories that product groups belong to.

They are typically aligned to business areas such as **tyres**, **accessories**, **labour charges** or **other sales categories**.

Each product group must be assigned to a product supergroup.

Product supergroups can be viewed and edited by selecting **System > System Files > Products > Product Supergroups** from the menu bar.

### Adding Product Supergroups

#### System > System Files > Products > Product Supergroups

New product supergroups can be added by clicking on the **Add** button at the top of the Supergroup Maintenance window.

The **Add Supergroup** window will open.

**In the Details tab:**

- Enter a unique **Code** and **Name**
- Select a **[Department](/gtx/docs/departments)**
- (Optional) Select a **Markup Set**

          Warning

          

Product supergroup codes cannot be changed once they are added.

## Assigning Product Groups to Supergroups

#### System > System Files > Products > Product Groups

Each product group must be linked to a product supergroup.

Product groups can be assigned to a supergroup using the **Product Supergroup** picker in the [product group's Details tab](/gtx/docs/product-groups-1#adding-product-groups).

          Note

          

Supergroups must exist before product groups can be added.
