To ship using SmartSaver with ShipStation:
-
Create GlobalPost SmartSaver shipping labels for all the individual shipments by selecting one of the GlobalPost SmartSaver options from your Services drop-down.
Put all the SmartSaver shipments into a single larger package.
Create a manual order in ShipStation destined for the GlobalPost sorting facility, using the weight and dimensions of the larger package containing the SmartSaver shipments.
-
Select UPS Ground or FedEx Ground as the shipping services (based on your agreement with GlobalPost) and assign Third-Party-Billing information to the shipment.
Stamps will provide you with the required Third-Party-Billing information.
Use Automation Rules!
Automate this step with Automation Rules.
We recommend creating a manual store specifically for the consolidation orders, then use the manual store as criteria for an automation rule that assigns the service and Third-Party-Billing information.
Create the label and attach it to the larger package. Then it hand over to the carrier (either UPS or Fedex).
Notes About GlobalPost Services in ShipStation
The label that you'll print from ShipStation will be a domestic USPS shipping label. This label is used to ship your package to a GlobalPost sorting facility, where GlobalPost will relabel the package with any necessary documents for international shipping.
You will not print customs forms in ShipStation. ShipStation will submit the customs information electronically and GlobalPost will include any necessary customs documents when the package is relabeled at their sorting facility.
GlobalPost labels use funds from your Stamps.com balance.
All GlobalPost shipments include $100 of standard coverage. Additional Carrier Insurance is not available for GlobalPost shipments. Shipsurance is available, with a maximum declared value of $400.

GlobalPost Economy International and GlobalPost Standard International shipments can be included on USPS SCAN or End of Day forms.

There are two tracking numbers associated with a GlobalPost shipment:
The GlobalPost tracking number. ShipStation sends this tracking number to your customer and selling channel during ShipStation's notification processes. For Economy shipments, packages are tracked only to the GlobalPost sorting facility. For Standard and Smartsaver shipments, packages are tracked to the destination address.
The tracking number on the actual label generated in ShipStation. This tracking number can only be used to track the movement from your Ship From Location to the GlobalPost sorting facility. It is not shared with your customer or selling channel.

Here are some common issues, potential causes, and troubleshooting tips.
Issue |
How to troubleshoot or resolve |
|---|---|
Why aren't my First Class Mail International (FCMI) shipments' tracking numbers being sent to my customers or selling channel? |
The tracking number provided for FCMI shipments is not always fully trackable, and will often not provide any additional tracking details beyond the shipment leaving the country. Since these tracking numbers do not always provide full delivery information, ShipStation considers them to be non-trackable tracking numbers and will not include them in notifications by default. If you want ShipStation to include FCMI tracking numbers in notifications, go to |
My Priority Mail Express shipment arrived late, how do I get a refund for the late delivery? |
Contact the ShipStation User Success team with the tracking number(s) and created date(s) for the shipment(s). The ShipStation User Success team will evaluate the claim and respond within 24 hours. |
I created a shipment using the First Class Mail International (FCMI) service and the Large Envelope or Flat package type but got a domestic shipping label. What should I do? |
Starting in early 2018, USPS requires all "Merchandise" shipped using FCMI to use the Package package type. The Large Envelope or Flat package type is only valid if the content type for the shipment is "Documents." Stamps.com allows their users to use the Large Envelope or Flat package type for any kind of FCMI shipment, but in order to do so the shipment must go through GlobalPost, an international consolidation service. The domestic shipping label you received is used to ship your package to the GlobalPost sorting facility. Once received, GlobalPost will relabel the shipment with a new label and any necessary customs information, and send the package on it's way to it's final destination. See our section on GlobalPost for more details. |
