Connect your Fulfillment account, send orders to your Fulfillment provider, add Fulfillment SKUs to product records.
If you ship your orders through a fulfillment service, you can still use ShipStation to manage your shipping needs.
ShipStation integrates directly with multiple fulfillment providers so you can send orders directly to those providers using ShipStation (we even provide an automated way to do it!).
For fulfillment providers or drop shippers ShipStation doesn't integrate with, review our Dropshipping with ShipStation article to learn about your options.
Review the sections below for details on using our fulfillment service partners with ShipStation..
Before sending orders to fulfillment, you must first add a Fulfillment Provider, and ensure the SKUs associated with your products match the SKUs listed in your fulfillment provider account.
Note
If you don't have a Fulfillment Provider account yet, review our Fulfillment Provider integration articles to learn more!
Before you can send orders for fulfillment, you must connect your Fulfillment Provider account to ShipStation. If you have not yet connected your fulfillment provider, review the instructions in the article for the provider you use:
-
At this time, you can only add one FBA account per country to a single ShipStation account. For example, you can add one FBA (US), FBA UK, and FBA CA account to a single ShipStation account, but you cannot add two separate FBA (US) accounts.
Once connected, the account will be available as a Ship From Location for your orders. You can then send orders manually to the fulfillment provider or create an automation rule that will send them automatically when they import.
Currently, you can only send individual orders to fulfillment when using ShipStation's new layout. We are working on the ability to send in bulk. Check back soon!
To send an order to your fulfillment provider from ShipStation, either select the order in the Orders grid or open the Order Details screen. Then do the following:
ShipStation then sends the order to the fulfillment provider and creates a fulfillment record in the Pending status, which you can view in the Shipments > Fulfillments
page.
Use Automation Rules to Set the Service
Avoid the manual process by setting up Automation Rules to automatically set the service when the order imports.
To automatically send orders to a fulfillment provider as soon as they import from your stores, you'll need to create an Automation Rule. An automation rule will apply to orders based on the criteria you set in the rule, so before taking this step make sure you've determined what criteria the rule should be based on.
Going forward, orders that match the criteria set in the rule will automatically be sent to the fulfillment provider with the selected service. Repeat the above steps to create additional automation rules for different fulfillment scenarios.
To apply this new rule to orders that have already imported and are Awaiting Shipment, click the Reprocess Automation Rules button under the list of automation rules.
When Fulfilling Items in an Order Separately
The above rule will apply to the entire order, sending all items in the order to fulfillment. If some items in an order go to fulfillment, but others do not, or the items need to be fulfilled by separate fulfillment centers, do not use automation rules as the creation of multiple shipments for an order cannot yet be automated.
Instead, create multiple shipments in the order and use the manual Send to Fulfillment option.
The SKU ShipStation sends to your fulfillment provider must match the SKU the provider has listed for that product. If the SKU that imports from your store matches the Fulfillment Provider's SKU for that item, you have no further steps to take!
If the Fulfillment Provider SKU is different than the SKU from your store, however, you must enter a Fulfillment SKU in ShipStation before you can successfully send orders for fulfillment.
For products with a Fulfillment SKU, ShipStation will send this SKU to the fulfillment provider instead of the SKU imported on the order.
Update Fulfillment SKU for Multiple Products
To update the Fulfillment SKU for multiple products at once, use the Product CSV import process. Enter the Fulfillment SKU into the FillSku field in your CSV.
If you use ShipStation Legacy, you can still leverage ShipStation's integrations with FBA and Shipwire so you can send your orders directly to these fulfillment services.

Once you have connected your Fulfillment Provider account to ShipStation, the account will be available as a Ship From Location for your orders. You can then send orders manually to the fulfillment provider or create an automation rule that will send them automatically when they import.
This will send the order to the selected fulfillment service and update the status in ShipStation to the Pending Fulfillment status.
Limited Time to Cancel Fulfillments Once Sent
If you sent the fulfillment with incorrect information or created the fulfillment in error, you have a limited amount of time to cancel the fulfillment.
To automatically send orders to either FBA or Shipwire as soon as they import from your stores, you'll need to create an automation rule. An automation rule will apply to orders based on the criteria you set in the rule, so before taking this step make sure you've determined what criteria the rule should be based on.
Going forward, orders that match the criteria set in the rule will automatically be sent to the fulfillment provider with the selected service. Repeat the above steps to create additional automation rules for different fulfillment scenarios.

Warning
The above rule will apply to the entire order, sending all items in the order to fulfillment. If some items in an order go to fulfillment, but others do not, or the items need to be fulfilled by separate fulfillment centers, do not use automation rules as the creation of multiple shipments for an order cannot be automated in ShipStation Legacy.

Update Fulfillment SKU for Multiple Products
To update the Fulfillment SKU for multiple products at once, use the Product CSV import process. Enter the Fulfillment SKU into the FillSku field in your CSV.
After creating a fulfillment, there is a limited amount of time to cancel the request successfully. If the fulfillment process has not yet started, follow the steps below to cancel the fulfillment.
The order will move to the Pending Cancellation status until the cancellation is confirmed by the fulfillment provider. If the order cancellations was successful, it will move back to the Awaiting Shipment status.
To view the fulfillment status, go to the Shipments tab, then select the Fulfillments from the left hand sidebar.

We receive incremental updates from Shipwire and FBA regarding the order status. However, you can also select one or many orders and click Update Status(es) for the most up to date status.

Once the fulfillment updates as Shipped, ShipStation transmits the shipping information back to the original sales platform.
