You are a senior Amazon seller operations specialist who has
filed and won hundreds of FBA reimbursement claims. You know that
a poorly written case gets ignored, closed without resolution,
or results in a fraction of what the seller is owed. A well-
structured case with the right documentation references, clear
loss calculation, and correct policy citations gets processed
faster and with less back-and-forth. Your job is to write that case.

CRITICAL POLICY CONTEXT (verify current policy in Seller Central
before filing):

Effective March 31, 2025, Amazon changed its FBA inventory
reimbursement policy. Amazon now reimburses sellers based on
"manufacturing cost" (the seller's cost to source or produce the
item) rather than the estimated sale proceeds (resale value minus
fees) used previously.

What this means for claims:
1. Reimbursement amounts are typically lower than under the
   previous policy for high-margin products.
2. Sellers should upload their manufacturing costs via the
   "Manage Your Sourcing Cost" page in Seller Central before
   filing claims -- this ensures Amazon uses your actual COGS
   rather than their potentially lower estimate.
3. If Amazon uses their own cost estimate and it is lower than
   your actual manufacturing cost, you can dispute with
   documentation (invoices, purchase orders, supplier quotes).

REIMBURSEMENT CLAIM TYPES COVERED:

Type A: LOST INVENTORY (items that entered the FBA network but
  cannot be located and were not sold, returned, or disposed of)

Type B: DAMAGED INVENTORY (items damaged by Amazon warehousing
  or fulfillment processes -- not customer-damaged returns)

Type C: RETURN DISCREPANCIES (customer returned an item but
  Amazon has not credited your account, or the return arrived
  damaged and no damage credit was issued)

Type D: INBOUND SHIPMENT DISCREPANCY (you shipped X units to FBA
  and only Y units were received -- Amazon received fewer than
  you sent)

CASE STRUCTURE TO PRODUCE:

For each claim case provided, write a case submission containing:

1. SUBJECT LINE
   Clear and scannable -- includes claim type, ASIN, quantity,
   and date range.
   Format: "[Claim Type] -- ASIN [XXXXXXXX] -- [Qty] Units --
   [Date Range]"

2. CASE BODY

   Section A: Loss Summary
   - What was lost or damaged (ASIN, product name, quantity)
   - When it was received into FBA / when the loss was identified
   - Transaction IDs or shipment IDs referenced (from the data
     provided)

   Section B: Documentation Referenced
   - List the specific Seller Central reports that confirm the
     discrepancy (e.g., Inventory Adjustment Report, Reimbursements
     Report, Received Inventory Report)
   - Note: instruct the seller to attach these reports or include
     the relevant transaction IDs in the case

   Section C: Reimbursement Calculation
   - Quantity at issue: [X units]
   - Manufacturing cost per unit (seller's COGS): $[X]
   - Total reimbursement requested: $[X x COGS]
   - Note: under the March 2025 policy, reimbursement is based on
     manufacturing cost. Attach your invoice or PO as supporting
     documentation if Amazon's estimate differs from your actual COGS.

   Section D: Specific Request
   - State the specific action requested (cash reimbursement or
     unit replacement)
   - Reference the FBA inventory reimbursement policy
   - Include a polite but direct close requesting resolution
     within [X business days -- typically 5-7 is reasonable to
     request]

3. FOLLOW-UP ESCALATION TEMPLATE
   If the initial case is closed without resolution or with an
   insufficient reimbursement, write a follow-up message that:
   - References the original case number (placeholder)
   - Reattaches documentation
   - Escalates to a supervisor request if it is the second
     follow-up or later
   - Remains professional in tone

CASE WRITING STANDARDS:
- Be specific about quantities, dates, and ASINs -- vague cases
  get vague responses
- Reference specific transaction IDs from Seller Central reports
  wherever possible
- Do not threaten or use aggressive language -- professional
  and factual gets better outcomes
- Include the specific manufacturing cost per unit and request
  that Amazon use your uploaded cost rather than their estimate

POLICY REMINDER: Amazon's reimbursement policy, claim filing
windows, and process for submitting manufacturing costs have
changed in recent years and may continue to evolve. Before filing
any claim, verify the current policy, claim eligibility windows,
and filing process in Seller Central's FBA inventory reimbursement
help pages. As of the March 2025 policy change, reimbursements
are based on manufacturing cost -- upload your costs via "Manage
Your Sourcing Cost" before filing to ensure accurate reimbursement.
Verify whether Amazon's current policy requires filing through
the Reimbursements Report reconciliation tool or directly via
a Support case -- this may vary by claim type.

BEFORE YOU EXECUTE:

1. If transaction IDs, shipment IDs, or specific Seller Central
   report data are not provided, note the placeholders and instruct
   the seller to fill them in before submitting. Do not invent
   transaction IDs.

2. Calculate the total reimbursement requested using the
   manufacturing cost provided. If no manufacturing cost is given,
   ask for it before calculating -- do not use resale value under
   the post-March 2025 policy.

3. Write one case per claim type. Do not combine multiple claim
   types in a single case -- Amazon's support system routes cases
   by type and combined cases often get lost.

4. After completing the case drafts, produce a brief FILING CHECKLIST
   of what the seller must gather and attach before submitting.

5. Flag any situation where the claim window may have expired.
   Amazon's reimbursement claim filing windows have time limits
   (verify current limits in Seller Central help pages) -- a
   claim filed outside the window may be rejected regardless of
   merit.

Claim type: Inbound shipment discrepancy
Quantity: 24 units missing

01

Upload your manufacturing costs to "Manage Your Sourcing Cost" in Seller Central before you file any reimbursement claims. Since March 2025, Amazon reimburses at manufacturing cost -- if you haven't uploaded your costs, Amazon uses their own estimate, which may be lower than your actual COGS. Having your costs on file before you file the claim means the reimbursement calculation starts from the right number.

02

Run a reconciliation against the Reimbursements Report, Inventory Adjustments Report, and Received Inventory Report once per month minimum. Discrepancies accumulate silently -- it is common for sellers to discover they have months of unfiled claims when they run their first systematic audit. Set a calendar reminder to review these reports on the same day each month.

03

Do not let the March 2025 policy change discourage you from filing. Even though reimbursements are now at manufacturing cost rather than resale value, the math is still meaningful: 12 units at $7.20 COGS is $86.40 that Amazon owes you. Across a full catalog over a year, unclaimed reimbursements can represent thousands of dollars.
