Amazon logistics centers process millions of fulfillment packages daily, resulting in lost stock, uncredited customer returns, and inaccurate dimensional weight measurements across thousands of seller accounts.
According to marketplace data, between 1% and 3% of an Amazon seller’s total annual FBA inventory value is lost, damaged, or miscalculated by Amazon warehouse fulfillment networks without automatic reimbursement.
While Amazon’s internal policies mandate financial compensation for fulfillment discrepancies, the platform rarely credits seller accounts proactively. Sellers must identify anomalies, gather tracking documentation, and open individual dispute cases manually.
For high-volume merchants, manual claim reconciliation requires dozens of operational hours every month. Seller Investigators automates this recovery pipeline entirely, combining cloud API scanning with dedicated human claim auditors.
What Is Seller Investigators?
Seller Investigators is an enterprise Amazon reimbursement platform, operating as a core division of Carbon6, that automates the discovery and financial recovery of FBA inventory losses, inbound shipment discrepancies, destroyed goods, and referral fee calculation errors.
Acquired by the e-commerce software conglomerate Carbon6, Seller Investigators connects securely to Amazon Seller Central via the official Selling Partner API. The software scans deep transactional reports dating back 18 months.
Unlike basic software plugins that generate raw spreadsheet exports leaving sellers to file cases themselves, Seller Investigators operates a hybrid recovery model. Advanced algorithms detect claim discrepancies, while dedicated human case managers file disputes manually.
This manual submission workflow maintains 100% compliance with strict Amazon Seller Central policies. Amazon forbids automated bot submissions, making Seller Investigators’ human oversight a vital safeguard against account suspension risk.
How Seller Investigators Audits Your Amazon Account
Seller Investigators audits your Amazon Seller Central account by cross-referencing inventory reconciliation reports, customer return logs, inbound carrier shipping documents, and dimensional fee tables to locate unclaimed reimbursements across 30 distinct discrepancy categories.
The operational workflow executes systematically across four structured phases. The complete recovery process is detailed below.
1. Initial 18-Month Retrospective Account Scan
Upon connecting your Amazon Seller Central account via the secure Selling Partner API, Seller Investigators pulls 18 months of historical transactional records to identify expired and uncredited fulfillment claims immediately.
Amazon enforces strict statutory time limits on reimbursement claims. Inventory lost inside fulfillment centers must be claimed within 18 months, while customer return discrepancies expire within 60 to 120 days depending on claim category.
The initial audit identifies immediate cash recovery opportunities. Sellers frequently discover several thousand dollars in historical uncredited claims during their initial 48 hours on the platform without paying upfront service fees.
2. Algorithmic Discrepancy Detection
The platform’s proprietary algorithms continuously monitor real-time FBA inventory logs, comparing items checked into fulfillment centers against customer orders, returned units, and damaged warehouse write-offs to pinpoint discrepancies instantly.
The engine flags instances where Amazon issued a customer refund but failed to return the physical unit to your inventory within the mandatory 45-day window. It also tracks items marked damaged by warehouse staff.
Additionally, the system tracks inbound logistics shipments. If you shipped 1,000 units to an Amazon fulfillment center and receiving staff only checked in 920 units, the discrepancy is queued for investigation automatically.
3. Dedicated Human Case Management
Experienced human claims specialists review every flagged inventory discrepancy, verify manufacturer invoices and carrier delivery proofs, and manually submit individual cases directly to Amazon Seller Support staff.
Submitting claims manually is critical because Amazon actively detects and rejects automated bot submissions. Automated mass ticket creation violates Amazon terms and can trigger account review flags.
Seller Investigators’ human team navigates Seller Support rejections, submits required supplementary documentation, and escalates stalled claims until funds are credited directly to your Seller Central account balance.
4. Dashboard Reporting and Fund Reconciliation
The Seller Investigators analytics dashboard provides transparent, real-time reporting on total recovered capital, active claim statuses, historical audit logs, and fee reimbursements credited directly to your Amazon account.
Recovered funds are never routed through third-party bank accounts. Amazon deposits reimbursements directly into your standard Seller Central balance during regular bi-weekly disbursements, ensuring absolute capital security.
Seller Investigators bills its success fee commission only after funds are verified as deposited inside your Amazon account. You receive an itemized invoice detailing each specific reimbursed Amazon transaction ID.
Primary Amazon Reimbursement Categories Covered
Seller Investigators covers over 30 distinct reimbursement categories across inbound logistics, fulfillment center storage, customer return discrepancies, and incorrect dimensional weight fee classifications. The primary claim categories are detailed below.
Key FBA Reimbursement Discrepancies Recovered:
- Lost Warehouse Inventory: Products misplaced by Amazon staff during inter-facility transfers or storage.
- Damaged Warehouse Goods: Inventory crushed, broken, or water-damaged by forklift operators or warehouse machinery.
- Unreturned Customer Refunds: Orders where Amazon refunded the customer but the buyer failed to return the item within 45 days.
- Inbound Receiving Shortages: Shipments where receiving dock workers checked in fewer units than carrier bills of lading show.
- Destroyed Inventory Without Consent: Unsellable units disposed of by warehouse personnel without seller authorization.
- Dimensional Weight (Cubiscan) Overcharges: Excessive FBA fulfillment fees caused by incorrect packaging size measurements.
Dimensional weight measurement errors represent one of the most lucrative ongoing recovery categories. When Amazon scanners misread packaging dimensions by even half an inch, per-unit fulfillment fees increase drastically across thousands of orders.
Seller Investigators identifies these measurement discrepancies, requests official Cubiscan re-measurements, and secures retroactive fee refunds spanning previous months of overcharged sales volume.

Pros and Cons of Seller Investigators
Evaluating Seller Investigators requires weighing the substantial financial benefits of fully automated claims recovery against the standard 25% performance commission. The verified operational trade-offs are outlined below.
Seller Investigators Advantages
The primary advantages of Seller Investigators include comprehensive 18-month historical auditing, 100% manual claim filing by human specialists, zero monthly software subscription fees, and transparent reporting.
Merchants save hundreds of hours of manual administrative labor while recovering cash that would otherwise expire under Amazon statutory limitation deadlines. The Carbon6 backing ensures robust infrastructure security.
In addition, the dedicated case managers resolve complex inbound shipping discrepancies that standard automated spreadsheet tools cannot process, securing substantial cash recoveries on lost freight shipments.
Seller Investigators Considerations
The primary consideration for Seller Investigators is the 25% performance commission rate, which is higher than doing manual claim filing yourself inside Seller Central.
Very small sellers generating under $2,000 per month in gross sales may prefer filing simple customer return claims manually using free Seller Central reports to preserve maximum profit margins.
However, for merchants doing $10,000 or more in monthly volume, the operational time saved and additional discrepancy categories recovered far outweigh the commission percentage.

5. Review discovered claim opportunities inside your dashboard and monitor real-time cash reimbursements deposited directly into your Seller Central balance.
Practitioner Verdict: Is Seller Investigators Worth It in 2026?
Seller Investigators is unequivocally worth activating for any Amazon FBA merchant doing over $10,000 in monthly sales, delivering an automated, risk-free cash injection from otherwise lost inventory capital.
Because the platform operates on a pure performance model with zero upfront costs, there is no financial downside to running the initial 18-month audit. Unrecovered inventory simply represents abandoned revenue left inside Amazon fulfillment centers.
With human claim submission preventing account suspension risks and promo code Sellerfree500 providing $500 in completely free recoveries, connecting Seller Investigators is a standard operational necessity for serious private label and wholesale brand owners.
