# Adjust Inventory Available

| Step Details |
| --- |
| **Introduced in Version** | 9.22 |
| **Last Modified in Version** | 9.22 |
| **Location** | Integration > Shopify > Inventory |

The **Adjust Inventory Available** step updates the available inventory quantity for a specific inventory item at a given location in a Shopify store using the Shopify Admin API. This step allows inventory levels to be incremented or decremented based on operational needs.

This step is commonly used in scenarios such as order fulfillment, stock adjustments, or syncing inventory levels with external systems. It can be combined with steps that retrieve inventory item IDs and location IDs to accurately manage stock across multiple locations.

### Prerequisites

This step requires the Shopify module to be [installed](https://documentation.decisions.com/docs/installing-modules-decisions) and a configured OAuth token with appropriate Shopify Admin API scopes (such as **write_inventory**).
