# Step 3: Set Up Inventory

With your catalog and channels in place, load your current stock levels. Moselle uses this to identify what's at risk and what needs to be ordered.

**Time required:** 15–20 minutes

***

## Step 1: Create a Warehouse

1. Go to **Inventory** in the left nav
2. Click the **Warehouse** tab
3. Click **+ Add Warehouse**
4. Enter your warehouse name and address details
5. Click **Create**

{% hint style="info" %}
**Already on Shopify or Amazon?** A synced warehouse for those integrations may already exist under the Warehouse tab. Check before creating a new one.
{% endhint %}

For full warehouse type details, see [Create a Warehouse](/operations/inventory/create-a-warehouse.md).

***

## Step 2: Upload Your Stock Levels

For manual warehouses, upload a snapshot of your current available inventory.

{% stepper %}
{% step %}

### Get the CSV Template

1. Go to **Inventory** → select your warehouse
2. Click **Update Warehouse** → **Upload Inventory Snapshot**
3. Download the **CSV Template**
   {% endstep %}

{% step %}

### Fill In Your Stock

The CSV requires two columns:

| Column      | Description                                              |
| ----------- | -------------------------------------------------------- |
| `sku`       | Must match your catalog SKUs exactly (case-sensitive)    |
| `available` | Current units available (use `0` for out-of-stock items) |

{% hint style="warning" %}
SKUs must match your catalog exactly. Mismatched SKUs will be skipped without an error.
{% endhint %}
{% endstep %}

{% step %}

### Upload the File

1. Return to **Upload Inventory Snapshot**
2. Drag and drop or browse for your CSV
3. Click **Upload**
4. Check that stock levels appear correctly in the warehouse view

{% hint style="success" %}
Your inventory is loaded. Moselle will now use these levels in planning.
{% endhint %}
{% endstep %}
{% endstepper %}

## Mo Tip: Let Mo Reformat Your Stock Spreadsheet

If your inventory is tracked in a spreadsheet with a different layout, drop it into Mo and ask:

> *"Help me reformat this stock spreadsheet into a Moselle inventory CSV. Required columns are SKU and available quantity."*

Mo will map your columns to the correct format so you can upload without manual reformatting.
