We want to keep you up to date as we release new features and update ShipStation's functionality. This release information focuses on what's new and what's changed from our ShipStation Legacy interface in our most recent version of ShipStation (previously known as ShipStation V3).
We are excited to show you the new features ShipStation has to offer! If you'd like to take advantage of these new features but are still using the ShipStation Legacy interface, please contact us to let us know that you'd like to migrate to the new ShipStation experience.
ShipStation has added the ability to save multiple Tax ID numbers in ShipStation's International Settings. Once saved, the Tax ID numbers can then be applied to your shipments in their Customs Declarations. This allows ShipStation to add the necessary Tax ID numbers to the shipment's customs form or commercial invoice.
ShipStation will display a list of the Tax Identifiers that have been added. The Tax ID details cannot be modified once added. If you need to make a change to an entry, you must delete the entry and add a new one.

New features and updated functionality released in November 2020.
ShipStation's new layout has added a Fulfillments section to the Shipments page. Now, any order you fulfill with one of ShipStation's integrated fulfillment providers or any order you mark as shipped will have a fulfillment record in this new Fulfillments section. Previously, all records appeared as shipment records. Now, you now have a separate section to view your fulfillments so you can differentiate between orders you have shipped in-house and those orders you marked as shipped or sent to your fulfillment provider.
The Fulfillments statuses are similar to the Shipments statuses: Recent, Pending, In Transit, Delivered, Delivery Exception, and Cancelled fulfillments.

As the fulfillment providers send us status updates, the fulfillment request status moves from Pending to In Transit to Delivered.
Date Filters
The date filter for each section in the Fulfillments section defaults to show records for the last 8 days from the current date (for example, Sunday - Sunday).
Fulfillment Statuses
Click into any of the Fulfillments statuses to view all matching shipments.
Status |
Meaning |
---|---|
Recent |
Last 8 days of ANY fulfillments, regardless of status. Use the Ship Date filter to view a different date range. |
Pending |
Shipments that are sent to fulfillment but not yet fulfilled will appear in Pending Fulfillment. Additionally, Amazon Seller Fulfilled Prime orders will import as Pending Fulfillment, unless Amazon Buy Shipping has been enabled in the ShipStation account. |
In Transit |
The shipment has been sent by the fulfillment provider. The fulfillment record will remain in this status until delivered. Hover your cursor over the icon to get more details. |
Delivered |
The carrier has dropped off the shipment at the destination. |
Delivery Exception |
The shipment has failed to reach its final destination due to issues like rerouting back to the sender, an obstructed mailbox, the recipient refusing the package, or failed delivery attempts. |
Cancelled |
Shipments sent to fulfillment then cancelled, either by the merchant or the fulfillment provider. |
Available Actions for Fulfillment Records
Action |
Result |
---|---|
Cancel Fulfillments |
Within the Recent and Pending statuses, you can select one or more fulfillment records that are Pending fulfillment and click Cancel Fulfillment. This will attempt to cancel the Pending fulfillment. If successful it will move the shipment to the Cancelled status. |
Tracking / Status updates |
Within all of the statuses you can select one or more fulfillment records and click Update Status. ShipStation will request a status update from the provider and update the fulfillment status in ShipStation accordingly. |
Create Returns |
This action will open the Order Details and take you to the Create Return section. |
Export |
Within all of the statuses you can select one or more fulfillment records and click Export. Select the option to export all fulfillment records or only those you selected within the current status. |
ShipStation is adding a new Aggregate Inventory column in the Products grid. This column displays the aggregate inventory counts for a product from all internal and external inventory sources. In the column header, it also provides an option to view the last time inventory counts were updated.
ShipStation is rolling this feature out to all users through the end of the year, so may not be available to everyone immediately.
Product Records Must Have SKUs
ShipStation's Aggregate Inventory count only supports products that have SKUs. Products with just a listing name and no SKU will not show in Aggregate Inventory counts.
The aggregate count will show on the Products page in the Aggregate Inventory column. When first enabled, the column will appear as the farthest right column of the Products grid.

Hover your cursor over the icon in the Aggregate Inventory column header to see when the Available Inventory was last updated.

The Aggregate Inventory column will show only if you have a compatible Inventory source connected. As this feature is rolled out, ShipStation will progressively add the sources listed below to the feature.
If your inventory source is not in this table, the Aggregate Inventory column will not display in your Products grid.

3PLs (Third-Party Logistics) |
Other (marketplaces, shopping carts, etc.) |

The Aggregate Inventory column display is quite different than the inventory we display on the Inventory section on the Products page (ShipStation internal inventory only) and the inventory we display in Order Details (specific to 1 inventory source set in the Ship From Location set for the order). It is quite possible that the quantity displayed in this column could be different than the quantity displayed in your Order Details.
Aggregate Inventory displays the aggregate of all of the inventory sources you have connected, while the Order Details displays inventory from one specific source. When you select an order it will show the inventory from that one inventory source, not the aggregate.
Note
It is possible for you the merchant to have only ONE inventory source and that the count will match in both the Aggregate Inventory column and Order Details.
In the sample scenarios below, we use Shopify as an example of a compatible inventory source.
One Product, One Supported Inventory Source: In this example, you have inventory for Product A. You exclusively track inventory for Product A via Shopify (a compatible inventory source), and you have 50 units of Product A inventory in your warehouse there. The Products grid should display 50 units under the Aggregate Inventory column for Product A.
One Product, Two Supported Inventory Sources: In this example, you have inventory for Product B in two supported places. In ShipStation’s Internal Inventory, you have 50 units of Product B available. Via Shopify inventory at a warehouse, you have another 75 units available. So, on the Products grid under the Aggregate Inventory column for Product B, the count should display 125 units.
Mix of Supported/Unsupported Inventory Sources: In this example, you are connected to both Shopify and Unsupported Inventory. The Aggregate Inventory column will not be displayed for you because we do not support Unsupported Inventory counts in this column yet.
