# Chain catalog

> Add a product once and reuse it in every unit.

If you have several units, the **chain catalog** saves you from adding the same product at each one. You add the product once, with name, description, picture, and SKU, and each unit creates its own item from it.

> [!NOTE]
>
> Only the chain owner creates and edits catalog products. Other members can view them.

## Add a product

Open **Catalog** and click **New product**. Fill in:

* **Name** and **Description**, in Portuguese and, if you want, in English. The chain's default language is required.
* **SKU**, optional: your internal product code. It must be unique within the chain.
* **Picture**, which units inherit.

## Create an item from the catalog

In **Items** → **New item**, pick the product under **From the catalog**. Name, description, and picture are filled in with the chain's data, and you can adjust them before saving.

The item gets a **copy** of the data. Editing the product later doesn't change items already created, and each unit keeps its own subscribers. On the item page, **Source product** shows which catalog product it came from.

## Delete a product

Deleting a product removes it from the catalog. Items already created from it stay as they are, with their subscribers.
