Carrier Bill-to-Third Party Feature: Setup Guide
This article explains how to set up your account to use your own carrier credentials.
When to Use
Use this feature when:
-
Your company needs to ship products but wants the shipping charges billed to another carrier account
-
You’re fulfilling orders for a partner who covers shipping costs
-
You need to maintain shipping operations internally while billing to a parent company or subsidiary
-
You have a negotiated account with a major carrier (UPS, FedEx, etc.) that offers favorable shipping rates

Navigate to Global Settings (gear icon on lower left)

Click the Orders tab

Select the Carrier Services subtab
Step 2: Configure Carrier Credentials
-
Enter your Carrier account number

Authenticate with your carrier website user credentials (username & password)
-
Save your settings
-
(Optional) Set a Default Carrier by clicking the three dots on the right and selecting “Set as Default”

Step 3: Verify Setup
After completing the setup:
-
Your account should immediately begin using your own carrier rates

You can confirm the setup by testing shipping rate estimations for new orders
Updated: Credential Verification & Troubleshooting
Credential Verification / Common Failures
When credentials fail or label generation fails, it’s often because of mismatches or account linkage issues. Please ensure:
-
The login credentials (email / username + password) you enter are linked to that same carrier account number
-
If your login belongs to a different carrier account, the system will not generate labels
-
Validate this linkage inside the carrier’s portal (e.g. UPS.com login → Profile → Account Number)
Common failure causes:
Issue | Description / Cause | Resolution |
---|---|---|
Mismatched login & account number | User used login for a different account | Re-login to carrier portal, confirm correct account number, then reauthorize in Skupreme |
Locked or inactive account | The carrier may have placed a hold, or account needs review | Resolve any holds or outstanding verifications with the carrier’s support |
Multiple accounts under same organization | User credentials may have access to multiple accounts | Confirm which is the correct account and use those credentials |
Credential entry typo | Mistyped username, password, or account number | Double-check, reenter carefully |
Carrier-side verification or extra security | Carrier may require additional codes, two-factor auth, or security validation | Complete any pending verification steps in the carrier portal before setup |
If the credentials appear valid but still fail in Skupreme, try:
-
Logging in directly to the carrier portal to ensure account is active
-
Triggering a new authorization (reauthorize credentials)
-
Clearing saved credentials and re-entering them
If the issue persists, escalate to internal support.
FAQ / Escalation Guidance
Q: My credentials are correct but it still fails. What now?
-
Double check that the account isn’t locked, in collections, or under review
-
Confirm there are no additional carrier-level verification steps pending
-
Try using a different user credential (if your company has multiple users)
-
If repeated attempts fail, contact support for a guided session or screen share to walk through the process
Q: Can I get white-glove setup support?
Yes — for enterprise or high-volume users, we recommend offering a 1:1 walkthrough or screen-sharing session to assist in validating their carrier account setup.
Q: Do all carriers require the same credential setup?
No — while many require just account number + user credentials, some may require extra vendor codes, warehouse mappings, API credentials, or security tokens. Before entering into Skupreme, make sure to check your carrier’s documentation for any extra requirements.
Important Notes
-
Changes to carrier settings take effect immediately
-
This feature is fully supported and does not require additional development work
-
Even when using your own FEDEX/UPS account, Skupreme can still rate-shop — if your account’s rate is best, it will be chosen
-
Always validate your setup by testing a few shipments after configuration
-
Keep an eye on carrier notices or emails, in case your account’s status changes (e.g. locked, suspended)
