# Safety stock

Safety stock is a reserved buffer quantity that protects offline (in-store) sales from being cannibalized by online orders. Stock at or below the configured safety stock level is excluded from availability calculations ([AOS](/documentation/by-pillar/global-inventory-hub/stock/stock-availability.md#stock-availability-values) and [AFP](/documentation/by-pillar/global-inventory-hub/stock/stock-availability.md#stock-availability-values)) and from order routing — meaning a facility with stock equal to or less than its safety stock will not be considered for fulfilling online orders.

{% hint style="warning" %}
Safety stock is considered during order routing. If all facilities for an article have reached their safety stock level, the order may become unroutable.
{% endhint %}

## Configuration

Safety stock is configured per article and facility. Two levels are supported:

* **Global safety stock**: A single value applied automatically to all facilities for a given article. If a facility has no individual value set, the global value applies. This is only configurable via [API](https://fulfillmenttools.github.io/fulfillmenttools-api-reference-ui/#put-/api/safetystocks) by omitting the `facilityRef` in the request.
* **Facility-level safety stock**: A value configured for a specific facility, overriding the global value for that facility. This is configurable via [API](https://fulfillmenttools.github.io/fulfillmenttools-api-reference-ui/#put-/api/safetystocks) and [Backoffice](/documentation/backoffice/facility-view/inventory.md#what-is-safety-stock-and-how-is-it-edited).

{% hint style="info" %}
If both a global and a facility-level safety stock are configured, the facility-level value takes precedence for that facility.
{% endhint %}

## Safety stock in Backoffice

### Display

The stock detail view in the **Network view** shows safety stock at two levels:

* **Article header**: Displays the sum of all effective safety stock values across all facilities, giving a quick network-wide overview of total held-back stock.
* **Network module**: The **Safety stock** column shows the effective value per facility — regardless of whether it originates from a global or facility-level configuration.

### Configuration

Safety stock can be configured directly on the stock detail view:

* **Facility-level value**: Open the **three-dot menu** in the corresponding facility row in the Network module.

## API

Safety stock can also be managed via the [Safety stocks REST API](https://fulfillmenttools.github.io/fulfillmenttools-api-reference-ui/#put-/api/safetystocks) using a bulk `PUT` request to `/api/safetystocks`.

## FAQs

<details>

<summary>What happens when safety stock is reached?</summary>

Once the stock in a facility reaches or falls below the configured safety stock level, that facility's AOS and AFP for that article drop to 0. The facility is no longer considered for order routing.

<details>

<summary>Which value takes precedence — global or facility-level safety stock?</summary>

The facility-level safety stock always takes precedence over the global value. If no individual value is set, the global value applies.

</details>

<details>

<summary>What does the safety stock value in the article header show?</summary>
