## Safety Stock Configuration

### What is Safety Stock?

Safety stock is buffer inventory to protect against:

* Demand variability
* Supply delays
* Forecast errors

### Configuration Methods

| Method             | Description              | Best For               |
| ------------------ | ------------------------ | ---------------------- |
| **Fixed Quantity** | Set number of units      | Stable demand products |
| **Days of Cover**  | X days of average demand | Most products          |
| **Percentage**     | % of period demand       | Seasonal products      |

### Setting Up Safety Stock

<Steps>
  <Step title="Go to Inventory Settings">
    Navigate to inventory configuration
  </Step>

  <Step title="Find Safety Stock Section">
    Locate safety stock configuration
  </Step>

  <Step title="Choose Method">
    Select how to calculate safety stock
  </Step>

  <Step title="Set Values">
    Enter values by SKU/warehouse or globally
  </Step>

  <Step title="Save">
    Apply configuration
  </Step>
</Steps>

### Safety Stock Levels

| Setting     | Description                       |
| ----------- | --------------------------------- |
| **Minimum** | Lowest acceptable level           |
| **Target**  | Ideal inventory level             |
| **Maximum** | Upper limit (overstock threshold) |

## Fulfillment Mapping

### What is Fulfillment Mapping?

Defines which warehouses fulfill demand from which channels:

```
Channel → Warehouse(s)
```

### Why Fulfillment Mapping Matters

| Purpose                   | Benefit                             |
| ------------------------- | ----------------------------------- |
| **Inventory Allocation**  | Know where to stock                 |
| **Forecast Consumption**  | Project inventory at right location |
| **Order Recommendations** | Replenish correct warehouse         |

### Configuring Fulfillment

<Steps>
  <Step title="Go to Inventory Settings">
    Navigate to inventory configuration
  </Step>

  <Step title="Find Fulfillment Mapping">
    Locate fulfillment configuration
  </Step>

  <Step title="Map Channels to Warehouses">
    For each channel, select fulfilling warehouse(s)
  </Step>

  <Step title="Set Priority">
    If multiple warehouses, set priority order
  </Step>

  <Step title="Save">
    Apply mapping
  </Step>
</Steps>

### Example Mapping

| Channel    | Primary Warehouse  | Secondary     |
| ---------- | ------------------ | ------------- |
| Shopify US | East Coast DC      | West Coast DC |
| Amazon FBA | Amazon Fulfillment | -             |
| Wholesale  | Central Warehouse  | -             |
| Website CA | Canada DC          | East Coast DC |

### Multi-Warehouse Fulfillment

When multiple warehouses can fulfill:

| Setting          | Behavior                              |
| ---------------- | ------------------------------------- |
| **Primary Only** | Always use primary                    |
| **Fallback**     | Use secondary if primary out of stock |
| **Split**        | Distribute across warehouses          |

## Inventory States

### Understanding Inventory States

Tether tracks inventory in multiple states:

| State         | Description              |
| ------------- | ------------------------ |
| **On Hand**   | Physically in warehouse  |
| **Available** | On hand minus committed  |
| **Committed** | Reserved for orders      |
| **Incoming**  | In transit to warehouse  |
| **Sellable**  | Available for new orders |

### State Calculations

```
Sellable = On Hand - Committed + Incoming
Available = On Hand - Committed
```

### Configuring State Display

Choose which states to display:

<Steps>
  <Step title="Go to Settings">
    Navigate to inventory settings
  </Step>

  <Step title="Find Display Options">
    Locate inventory state configuration
  </Step>

  <Step title="Select States">
    Choose which states to show in dashboards
  </Step>

  <Step title="Save">
    Apply preferences
  </Step>
</Steps>

## Overstock Settings

### Configuring Overstock Alerts

Define when inventory is excessive:

| Method                 | Description                     |
| ---------------------- | ------------------------------- |
| **Days of Cover**      | Alert if > X days inventory     |
| **Multiple of Safety** | Alert if > X times safety stock |
| **Fixed Quantity**     | Alert if > specific amount      |

### Setting Overstock Thresholds

<Steps>
  <Step title="Go to Inventory Settings">
    Navigate to configuration
  </Step>

  <Step title="Find Overstock Section">
    Locate overstock threshold settings
  </Step>

  <Step title="Set Threshold">
    Define when to alert for overstock
  </Step>

  <Step title="Save">
    Apply settings
  </Step>
</Steps>

## Lead Time Defaults

### Default Lead Times

Set fallback lead times when not specified:

| Type           | Default Use                                |
| -------------- | ------------------------------------------ |
| **Supplier**   | When supplier capability not set           |
| **Transit**    | When warehouse-to-warehouse not configured |
| **Production** | For manufacturing orders                   |

### Configuring Defaults

<Steps>
  <Step title="Go to Settings">
    Navigate to inventory settings
  </Step>

  <Step title="Find Lead Time Defaults">
    Locate default lead time section
  </Step>

  <Step title="Set Values">
    Enter default days for each type
  </Step>

  <Step title="Save">
    Apply defaults
  </Step>
</Steps>

## Inventory Health Rules

### Health Status Configuration

Define thresholds for health status:

| Status           | Default Rule                                             |
| ---------------- | -------------------------------------------------------- |
| **Out of stock** | Effectively empty, with live demand                      |
| **Low**          | Position below the requirement from your authored layers |
| **Healthy**      | Position within the requirement and the cap              |
| **Constrained**  | Above cap, forced by a downstream storage limit          |
| **Overstock**    | Above the cap, with nothing forcing it                   |
| **No demand**    | Nothing consumes the SKU here this horizon               |

A location with no authored coverage policy is not judged at all — it reads **Not set** and shows no status. See [How runout and coverage status work](/inventory/coverage-and-runout) for how the requirement and cap are computed.

### Customizing Health Rules

Adjust thresholds based on your business:

| Parameter          | Adjustment           |
| ------------------ | -------------------- |
| **Critical Days**  | When to show urgent  |
| **Low Days**       | When to show warning |
| **Overstock Days** | When excess starts   |

## Best Practices

<AccordionGroup>
  <Accordion title="Start Conservative">
    Begin with higher safety stocks:

    * Learn demand patterns
    * Reduce gradually
    * Better to have excess initially
  </Accordion>

  <Accordion title="Segment by Product">
    Different settings for different products:

    * High-value: higher safety stock
    * Fast-moving: more buffer
    * Slow-moving: lower buffer
  </Accordion>

  <Accordion title="Review Regularly">
    Update settings as business changes:

    * Seasonal adjustments
    * After supply chain changes
    * When adding new products
  </Accordion>

  <Accordion title="Document Decisions">
    Keep records of configuration choices:

    * Why settings were chosen
    * Who approved
    * When to review
  </Accordion>
</AccordionGroup>

## Troubleshooting

### Incorrect Inventory Projections

**Possible causes:**

* Wrong fulfillment mapping
* Missing lead times
* Incorrect safety stock

**Solutions:**

1. Review fulfillment configuration
2. Verify lead times set
3. Check safety stock levels

### Missing Alerts

**Possible causes:**

* Thresholds too high/low
