To enable Deliverr's SFP fast tag, Deliverr requires adding a unique Deliverr FedEx sub-account to shipping settings. Amazon only allows accounts to have one carrier account per carrier.
Important: This Deliverr FedEx sub-account my only be used by Deliverr to purchase SFP orders shipped by Deliverr.
Deliverr's FedEx sub-accounts are unique to sellers, and Deliverr validates expected charges (for SFP orders fulfilled by Deliverr) against actual charges on that sub-account. If a discrepancy is uncovered, Deliverr will investigate, and possibly pause or deactivate the sub-account.
If Deliverr finds that a seller purchased a shipping label and/or services on Deliverr's FedEx sub-account without written authorization from Deliverr, then the seller will be charged the full cost of the shipping label and/or services plus a noncompliance fee of 2x the full cost.
For example, if a seller purchased a $10 shipping label on Deliverr's FedEx sub-account without written authorization, then the seller would be charged $30 ($10 for the shipping label + 2x the $10 cost).
