Amazon Carrier Adjustment & Shipping Charge Investigations
A record-level review for sellers who need to understand a carrier adjustment before deciding whether a dispute is supportable. No guaranteed outcome, invented proof or privileged carrier access.
Typical issue patterns
- Postage or shipment-charge adjustments that do not reconcile to the label or shipment record
- Declared versus audited weight or dimensions changing the charge
- Duplicate, repeated or unexplained deductions tied to the same shipment
- Tracking, order and transaction references that do not line up
- An adjustment with an audit reference, prior case or deadline that needs controlled review
RECONCILE → VERIFY → CLASSIFY → EVIDENCE → DISPUTE WHERE JUSTIFIED
We reconcile tracking, orders, transactions, shipping labels, declared and audited weight or dimensions, carrier references, Amazon deductions, prior cases and correspondence. Explainable charges are separated from evidence gaps and potential discrepancies before any supported dispute.
Evidence standard
Required to start
Marketplace, review period, carrier, approximate adjustment population, and any order, tracking or transaction references you can identify.
Useful to test the charge
Shipping labels, Buy Shipping status, deduction records, declared weight and dimensions, adjustment references, and prior case correspondence.
Needed to establish a discrepancy
A record-level comparison showing why the charge does not reconcile, supported by available Amazon, label, tracking or carrier material.
Boundaries
- We do not assume a charge is wrong or recommend a dispute without supporting records.
- We cannot guarantee reimbursement or recovery, obtain privileged carrier access, or replace Amazon or carrier decisions.
- We do not invent, alter or backfill proof; evidence gaps are reported as gaps.
- This is an evidence-led commercial review, not legal representation or generic shipping support.
Potential deliverables
- Shipment-level reconciliation
- Adjustment schedule
- Discrepancy classification
- Missing-evidence schedule
- Evidence pack
- Escalation record

The investigation can cover Amazon Buy Shipping and relevant USPS, UPS, FedEx or other-carrier adjustments, including postage, weight, dimensions, tracking, orders, transactions and deductions.
What information is useful for an initial review?
Marketplace, review period, carrier, Buy Shipping status, approximate adjustment count and value, whether tracking or order references and evidence are available, prior Seller Support cases, current status and any deadline.

What does the engagement include?
This is a case review or scoped investigation. Depending on scope, deliverables may include a shipment-level reconciliation, adjustment schedule, discrepancy classification, missing-evidence schedule, evidence pack and escalation record.
