LSO Shipping, Built Into ShipStation

Yes. ShipStation supports connecting your own active LSO account. During setup, you go to Account Settings, open Shipping and Carriers, choose the Your Carrier Accounts tab, click Add Carrier, and select LSO. If your plan requires the Your Carriers add-on, ShipStation prompts you during setup. If you do not have an LSO account yet, you can select the option to sign up for a new one while connecting.

You need a few specific details before setup starts:

• A US-based ShipStation account
• An active account with LSO
• Your LSO Account Number
• Your billing address

During setup, ShipStation asks for your Billing Street Number, Billing City, Billing State, Billing ZIP Code, and an Account Nickname. Having that ready makes the connection process smoother.

Yes. ShipStation supports estimated rates for LSO based on your connected account information and shipment details. That makes it easier to review service options before you buy a label and choose the best fit for the order. It is especially helpful when you need to weigh overnight, next-day, ground, or Mexico service options inside one workflow.

ShipStation supports a wide range of LSO services, so you can match the service level to the order instead of forcing every shipment into the same lane.

• LSO 2nd Day
• LSO Early Overnight
• LSO Economy Next Day
• LSO Ground
• LSO Plus
• LSO Priority Overnight
• LSO Saturday
• LSO eCommerce
• LSO Mexico

ShipStation also supports LSO package types like Package, Letter, Tube, custom packages, and several LSO-branded package options.

Yes. Shipping labels created for LSO in ShipStation include a tracking number you can use to view shipment status on the carrier’s tracking website. That gives your team and your customers better visibility after the label is created. Tracking may not be available for every LSO shipping service, so confirm the service you plan to use.

Yes. ShipStation supports domestic return labels for LSO. That helps you keep outbound labels and return workflows closer together instead of managing returns in a separate system. If your business handles frequent exchanges or product returns, that added control can make post-purchase operations easier for your team.

Yes. ShipStation supports international shipping labels for LSO shipments bound for Mexico. That gives merchants using LSO a direct way to manage both domestic shipments and Mexico-bound orders in the same shipping workflow. Electronic customs submission is not supported for LSO, so you should plan your international process with that limitation in mind.
