Service-failure timing
Flag recognized delivery delays and expose the earliest review date. FedEx's 2026 US Service Guide states that service-failure requests must use approved channels within the stated time window.
FedEx invoice audit / US payers
Find the invoice lines worth challenging.
A FedEx invoice can contain several different review jobs: service-failure requests, overcharge adjustments, duplicate payments, and surcharges that need original shipment evidence. OFFSET/15 separates those patterns instead of presenting one unreliable refund number.

What the audit checks
Findings with a reason.
Overcharge review
Keep possible billing overcharges distinct from money-back-guarantee requests because the carrier terms and deadlines differ.
Repeated line items
Find likely duplicate tracking, description, and amount combinations while avoiding double counting.
Exception handling
Route weather and other stated exceptions to manual review rather than labeling them guaranteed credits.
Evidence workflow
From export to decision.
- Redact
Keep the fields needed for invoice math while removing names, street addresses, and unrelated customer data.
- Review
Inspect the calculated amount, reason, source row, tracking reference, and any stated exception.
- Submit
Use the current FedEx Billing Online or invoice-adjustment workflow when the evidence supports a request.
Direct answers
Questions shippers ask.
What is the FedEx service-failure request window?
The 2026 US Service Guide states that requests for transportation-charge refunds or credits due to a service failure must be received within 15 calendar days of the invoice date, or the ship date for certain prepaid shipments. Always verify the current guide and your agreement.
Are FedEx overcharge adjustments the same as late-delivery credits?
No. The FedEx guide treats billing overcharges and service-failure requests separately and gives them different conditions.
Can the scanner guarantee a FedEx credit?
No. A finding is a review lead. FedEx terms, shipment evidence, account status, and carrier approval control the outcome.
