This article explains the steps to adjust the existing Stock level for a specific (single)
SKU.
1. Go to Products in the toolbar.
2. Select Inventory from the left-hand sidebar.
On this screen, you'll see all the existing stock levels for products that have configured inventory. (Be sure you've set up your initial stock levels already.)
You can modify the values in the Stock column by adding units, removing units, or setting the stock count to a certain amount.
3. Click on the appropriate symbol in the Actions column to get started:
When you add, remove, or set stock, you can add a note to help you remember why you made the adjustment. When you add stock, you can also specify your cost for those additional units.
These functions, including a history of changes, are also available via the Inventory tab in the Product Detail window.
That's it! Making an adjustment to a single stock level is simple, but it would be a lot of clicks to update multiple SKUs in this way. To update stock levels for multiple SKUs in a bulk process, please refer to this article.
NOTE: If you attempt to create a label for an order with a higher quantity than available inventory for a product, you will get an alert like this one:
You may choose to Override & Create Label if you still wish to ship this order. However, selecting this option will ignore your inventory levels entirely - meaning, no stock will deduct from your existing inventory levels. Use the steps above to manually adjust the levels if you need to.
