Nitromule

Refund a shipping label

Updated 2026-09-07

On this page

Refunds apply to unused labels you successfully void (or that Nitromule/the carrier marks refundable). Scanned packages are not refundable as unused postage.

Steps

  1. Confirm the package was never handed off and the label was never scanned.
  2. Void the unused label as soon as you know it will not ship.
  3. Wait for void confirmation in Nitromule.
  4. Watch Billing / transaction history for the postage credit (timing can lag carrier confirmation).
  5. If void succeeds but credit is missing after the normal window, contact support with order id and tracking number.

What is not refundable

  • Labels already scanned or in transit
  • Carrier adjustment fees unrelated to void
  • Duplicate labels you bought after forgetting reprint — void the unused one promptly instead of requesting a special refund

BYOA notes

When you ship on your own carrier account, refunds follow the carrier contract, not only Nitromule Billing. Void in Nitromule and confirm with UPS/USPS/FedEx as needed.
