The FBA reimbursement 60 day claim window
Since Amazon's March 31, 2025 policy change, most manual reimbursement claims have to be filed within 60 days of the loss. Miss the window and the case is usually gone — not denied, just expired. This guide explains how those 60 days are counted, why so many cases slip past the deadline, and what a realistic monthly routine looks like for a seller working alone.
What the window is and when it started
Before 2025, a seller could discover a loss from months or years back and still have a reasonable shot at a manual claim. Amazon tightened that as part of the March 31, 2025 changes — the same update that moved reimbursement to manufacturing cost and expanded automatic reimbursements. Under the current policy, most manual claims must be raised within 60 days of the event that caused the loss. Automatic reimbursements still happen on Amazon's own schedule, but the cases Amazon does not catch are now on a short clock.
The exact start date for a specific case is the date Amazon recorded the event — an adjustment line marking units lost in the Inventory Ledger, the receive date of a short-shipped inbound order. Not the day you noticed. A loss from March 20 that you find in June is not 20 days old; it is expired.
Why cases expire unseen
The deadline is not the hard part — the discovery is. A loss only becomes a claim once three things line up: you downloaded the right reports, you matched a loss row against the reimbursements paid back, and you noticed the gap. A few months of the detailed Inventory Ledger is thousands of rows across SKUs and dates, and a matching reimbursement often lands weeks after the loss it covers. The arithmetic is simple enough for a spreadsheet and tedious enough that most sellers never finish a pass. So the cases that expire are not the disputed ones — they are the ones nobody reconciled in time.
A monthly routine that fits the window
Sixty days means a quarterly reconciliation is too slow by design: by the time you run it, part of the period is already dead. Once a month works. The short version:
Download the Inventory Ledger (Reports → Fulfillment, Detailed view, one month at a time) and the Reimbursements report (Reports → Payments, full history). Reconcile losses against what was paid back, and flag every unmatched loss with its date. Anything already past 60 days is likely not eligible — knowing that is still worth something, because it stops you filing claims that go nowhere. Anything inside the window is a live case to file or verify. Our lost inventory reimbursement guide covers the download steps in detail.
Doing it in two minutes instead of an afternoon
We built SellerRecover to make the monthly pass cheap enough to actually happen. Upload the reports you already download — any filename, CSV or Excel — and the engine reconciles losses against reimbursements and sorts every case: potential reimbursement opportunity, already reimbursed, likely not eligible (including anything outside the 60-day window), or needs manual verification. The summary is free and shows what was found before any payment; the full audit is a flat $9, with the evidence and the next action for each live case, as PDF and CSV. No Seller Central access, no account, no commission.
If a case is already past 60 days
File it only if your own records show something different from what the reports say — a date mismatch, a reimbursement that was requested but never landed. Otherwise the honest answer is that the window closed: Amazon's own automatic reimbursements are the only path still open, and those depend on Amazon's detection, not yours. The better move is to make the next 60 days the first cycle you actually cover.
