# Can I add batch numbers to item groups and composite items?

Yes! You can add [serial numbers](/inventory/help/items/composite-items.html#serialized-composite-item) or [batch numbers](/inventory/help/items/composite-items.html#batch-tracked-composite-item) to composite items in Zoho Inventory.

Advanced tracking cannot be performed on an item group as a whole. However, you can track the variants individually. To do so:

*   Go to the **Item Groups** module and open a preferred item group.
*   Click-open an item under the **Item Details** section of the item group.
*   Click the **Pencil** icon on the top right corner of item details page.
*   Under **Advanced Inventory Tracking**, choose Batch Tracking or Serial Number Tracking. **Note:** To find this option, make sure to enable Batch Tracking or Serial Number Tracking under _**Settings > Preferences > Items**_ .
*   Click **Save**.

Likewise, you can enable advanced inventory tracking for the other variants in the item group.
