Lost Inventory
Units go missing in transit, between warehouses, or inside fulfillment centers. Amazon logs the discrepancy but does not pay it back on its own.
FBA Reimbursement Audit
Amazon Owes You Money. Most of It Never Gets Collected.
FBA errors drain 1 to 3% of your revenue every year. Lost inventory, warehouse damage, miscounted shipments. Amazon logs them. It just does not pay them back automatically.

01 · The Problem
The FBA System Isn't Broken. It's Just Not Working for You.
Amazon runs one of the most complex fulfillment operations on earth. Millions of units moving through dozens of warehouses, daily. At that volume, errors are inevitable and Amazon knows it.
Here is what gets missed: Amazon has a reimbursement system for exactly these errors. It is documented, and it almost never triggers without a claim. The gap between what Amazon owes and what you have collected is money sitting on the table.
At a Glance
- FBA errors affect virtually every active seller. Most go unfiled.
- Amazon's manual claim window dropped to as little as 60 days in late 2024, down from 18 months. Miss it and the money is gone for good.
- Adverio audits your full transaction history across every eligible error category.
- First reimbursements typically land within 3 to 4 weeks of audit completion.
- Your time investment: under 2 hours.
02 · Error Categories
What Amazon Owes You
Every one of these categories has a documented reimbursement path inside Amazon Seller Central. Most accounts have uncollected claims sitting in all four right now.
Warehouse Damage
Stock gets broken, rendered unsellable, or improperly disposed of. You are owed compensation.
Inbound Shipment Discrepancies
Amazon receives fewer units than you sent. The shortfall shows in their system, not your account.
Low-Ball Reimbursements
Amazon sometimes pays partial on valid claims. Accept without review and you leave the rest behind.

05 · What the Numbers Look Like
What the Numbers Look Like in Practice
Across the brands we have worked with, the pattern is consistent: accounts with no prior systematic audit process carry the largest recoverable pools. The longer errors go unfiled, the closer the 18-month window gets to eliminating them permanently.

06 · Why Adverio
We've Seen What Amazon Misses. And What Most Audits Miss Too.
At scale, FBA errors are not small line items. They compound.
A 1.5% drag on $5M in revenue is $75,000 a year.
This usually surfaces only after a first full audit. We have run hundreds of them.
What we look for that generic tools do not catch:
Units reimbursed at the wrong valuation (Amazon uses a cost estimate that is often low)
Inbound shipment disputes where the receiving window has nearly expired
Damage claims that were auto-closed before a human reviewed the documentation
Duplicate charges on storage, removal, or returns processing
The difference between a software scan and an actual audit is the quality of what gets filed. Amazon's dispute team has seen every auto-generated claim. They know what to push back on. We file with the documentation that gets approved.
This Is One Piece of the Profit Picture
Amazon reimbursements recover dollars Amazon already owes you. But margin leakage rarely stops at FBA errors.
Brands that come to us for a reimbursement audit walk away with a clearer view of where their P&L is bleeding: ad spend structure, listing conversion, Buy Box exposure, catalog health.

Frequently Asked Questions
Sometimes, for simple, clearly documented cases. But the automatic system misses a significant share of eligible errors, pays partial amounts on others, and never addresses claims that require dispute documentation. Most sellers who rely on the automatic process leave substantial money uncollected.
It depends on your revenue, category, and how long errors have gone unfiled. Brands in the $1M to $5M range typically recover $8,000 to $40,000 in their first audit. Larger accounts routinely surface more. We will give you an estimate after reviewing your account, before you commit to anything.
Not when done correctly. The risk comes from mass-filing poorly documented claims, which is what some software tools do. We file with specific, well-documented evidence on each claim, which is exactly what Amazon's process requires. We have run hundreds of audits without account incidents.
The initial audit typically spans 10 days. First reimbursements land within 3 to 4 weeks of audit completion.
No upfront fee. We work on a recovery share model. We only earn when you do. If the audit surfaces nothing, you pay nothing. Zero risk, full audit.
Every Month You Wait Is Another Month Amazon Keeps Your Money
The filing windows do not pause. On most lost and damaged claims, anything older than about 60 days is already gone. Last month's errors are still in reach, for now.
The audit takes less time than your last weekly meeting. The results show up in your account.
