In order for ShipStation to keep track of your stock levels, you need to set up at least one Inventory Warehouse and link it as an Inventory source to one of your Ship From Locations.
By linking an Inventory Warehouse to a Ship From Location, ShipStation will allocate available stock and deduct stock units from the correct location when you ship an order.
You can also configure your Inventory Warehouse to mirror your actual warehouse layout. For example, if your warehouse is broken down into aisles, rows, and bins, (warehouse locations that look like: B-24-7). By adding Locations, you can have ShipStation show specifically where each item is located.
Setup an Inventory Warehouse
Think of this as the physical location where you store your inventory.
1. Go to Settings > Inventory Management > Inventory Warehouse*
2. Click Add Inventory Warehouse, name it, and Save.
*Note: Feel free to use or edit the Default Warehouse that is already added by ShipStation, instead of creating a new one!
This step is not necessary to start using inventory, but can be helpful if your products are located in clearly defined locations within your warehouse.
Click on Manage Locations for the Inventory Warehouse you just created.
In the top right of this new window, there’s a Warehouse Layout dropdown. This is where you can configure how detailed you want your inventory locations to be for each warehouse. The options are: Area, Unit, Shelf, and Bin.
Check as many as apply to your warehouse.
If you plan on updating your stock levels manually, click Add Location in the Inventory Warehouse window. Then,when the locations' boxes appear, enter all of this warehouse’s Inventory Locations.
Repeat this process for all locations you need to add.
Don't forget to Save.
For more detailed instructions on this process of creating Inventory Locations, please read this article.
Note: If you import your new stock levels via CSV, you can also do this in bulk via CSV using the alternate method outlined in this article.
Every order in ShipStation must have a Ship From Location. By linking an Inventory Warehouse to a Ship From Location, ShipStation can allocate and deduct inventory within the warehouse.
A Ship From Location can only be linked to one Inventory Source at a time, so as long as an orders has the right Ship From Location selected, you’re all set!
You can, however, use the same Inventory Warehouse as the Inventory Source for multiple Ship From Locations. This is useful if you have the same SKU in multiple locations. Using multiple Ship From Locations in this way will allow inventory to deduct from the correct place.
To set up an Inventory Warehouse as the Inventory Source for a Ship From Location, go to Settings > Shipping > Ship From Location.
Click Edit for an existing Ship From Location (or click the green + Add a Ship From Location if you want to make a new one). Look for the Inventory Source option, and select the Inventory Warehouse you want to link.
Once selected, don’t forget to Save Changes!
This isn’t a required step, but once you’ve made the link, you can confirm it on the Inventory Warehouse section of your Settings page.
Notice that there’s a checkmark icon in the Linked to Ship From column:
Click Edit to see a list of all Ship From Locations using that Inventory Warehouse as an inventory source!
That’s it! You’re ready to add stock.
