ShipStation Carrier Services (SCS)

General details about ShipStation Carrier Services: Explanation of program, how to set up billing, and available features & services.

ShipStation Carrier Services (SCS) gives you one balance of funds to purchase labels from the available SCS carriers. Instead of purchasing labels and managing payments to multiple postal accounts, use just one balance for all labels.

Just as one wallet holds multiple credit cards, SCS acts like a single postage account in ShipStation. You'll also receive our select preferred rates for services from the included carriers. There’s no need to create individual accounts for each carrier you might wish to use. With ShipStation Carrier Services, just set up your preferred billing method and start purchasing labels.

For details about using SCS with our current partners, review the articles linked below (or in the article list on the left side of this page):

Notes about ShipStation Carrier Services

  • Post-shipping adjustments may occur with USPS and UPS from ShipStation services if actual package details (weight and dimensions) do not match the package details used to print the label. These adjustments are automatically deducted from your ShipStation Carrier Services account balance.

    • USPS uses an Automated Package Verification system to ensure the rate you pay for the label matches the service and rate requirements.

    • UPS uses dimensional weight (DIM), which requires package dimensions in addition to the weight to calculate properly. If you do not include package dimensions, UPS may apply an adjustment to your balance for the difference in the label cost after the shipment has been delivered.

    To view any adjustments that have been applied to your account, log into your Stamps.com account, go to the Reports > Balances page and set the Report Type to Transactions.

  • When you cancel your ShipStation account with any remaining balance, you will automatically receive a refund within 14 business days.

  • ShipStation handles all billing requests for ShipStation Carrier Services. To submit a request about billing, contact ShipStation's Support Team.

Dimensional weight, also known as volumetric weight, is a pricing technique for commercial transport (including courier and postal services) of larger packages with a lighter weight. DIM weight uses an estimated weight calculated from the length, width, and height of a package divided by a specific divisor determined by the carrier.

If DIM weight applies to your package, the carrier will compare the DIM weight and actual weight and charge the higher of the two for the label.
