Address Level
Sales and marketing > Customers > All customers < select a customer account < select Advanced from the More Options drop-down list in the Address FastTab
Click the Carrier Customer Account button on the ribbon of the Manage addresses form to configure third-party account numbers for each shipping carrier.
Enter the third-party account number in the Carrier customer account number field to tell the system which account number to charge when shipping with the specified carrier.
At the address level, you can set up more than one delivery location per customer per carrier.
You can then add a carrier customer account number for each delivery location. This allows you to have several carrier customer accounts for a single customer.
Note
The system uses the most-specific record configuration.
Address is more specific than account.
If you have two records set for a customer, one with a delivery location and one without, the system uses the record with the delivery location for that customer each time.
Navigate back to the Carrier customer accounts form accessed from the All Customers form to view all configured accounts, including account-level and address-level accounts.
