What access does Leviathan Sellers need to my Seller Central account?

Read-only access only. You invite Leviathan Sellers as a limited user in Seller Central with view-only permissions. We cannot make purchases, change your listings, move funds, or take any action — we can only read transaction data and file reimbursement claims through official Amazon channels.

Does Leviathan Sellers handle manufacturing cost documentation?

Yes. Since March 2025 Amazon reimburses at manufacturing cost rather than selling price. We prepare accurate, current cost of goods evidence for every claim. Without this documentation, Amazon uses its own lower internal estimate — typically 30–50% below actual cost — and you lose the difference permanently.

What if Amazon denies a claim Leviathan Sellers filed?

All denied claims are reviewed individually. Where the denial is contestable — which is the majority of cases — we re-file with strengthened evidence and a formal appeal. Denial is not the end of the process for us, it is the start of the appeal process.

How much does FBA reconciliation cost?

100% performance-based. We charge a commission only on amounts we actually recover for you. If we recover nothing, you pay nothing. The initial audit is completely free with no obligation. You only pay when you get paid.

The Problem

FBA Discrepancies Are Constant. The Window to Claim Them Is Not.

Amazon's warehouses check in billions of units a year. Errors happen across every stage — receiving, storage, returns, disposal. Most are correctable. But since January 2025, you have exactly 60 days to identify and file each one.

Since March 2025, every claim also requires manufacturing cost documentation. Without it, Amazon uses its own cost estimate — frequently 30–50% below your actual production cost.

🚫Claims Expire Permanently

After 60 days, every unclaimed discrepancy is gone. Amazon will not accept late filings under any circumstances.

📄Documentation Is Now Required

Manufacturing cost evidence must be accurate and current. Generic or missing documentation leads to underpayment or outright denial.

🤖Automation Tools Are Increasingly Rejected

Bulk-submission bots cannot prepare the tailored documentation Amazon now requires.

Every Type of FBA Discrepancy — Covered

🚫Lost Inventory

Units checked into an FBA centre but not reflected in inventory. Amazon is responsible for all units received.

One of the largest claim categories

🚧Damaged in Warehouse

Items damaged by Amazon employees or equipment during storage or fulfillment.

Requires documentation of unit value

↩️Return Discrepancies

Customer returns not checked back into sellable inventory or not reimbursed.

High frequency, lower per-unit value

⚙️Fee Overcharges

Wrong weight/dimensions, incorrect category assignment, duplicate fulfillment fee charges.

Ongoing — Amazon measurements drift

🚛Inbound Shipment Shortfalls

Units tracked to an FBA centre but not checked in correctly during receiving.

Common for high-volume shippers

🗑️Removal & Disposal Errors

Removal orders not returned correctly, disposal quantities not matching instructions.

Often missed in standard audits

Process

How We File Every Claim Correctly

📊Daily Audit

Every transaction reviewed daily — shipments, returns, fees, removals, disposals. No discrepancy expires without being identified.

📄Documentation Preparation

For each valid claim, we prepare tailored manufacturing-cost documentation and supporting evidence meeting Amazon's 2025 policy requirements exactly.

📤Individual Manual Filing

Claims are filed one by one through Amazon's official channels. No bulk automation. Each claim formatted, documented, and submitted individually.

💰Approval & Appeals

Approved claims credited directly to your Seller Central account. Denied claims reviewed and re-filed with strengthened evidence. Monthly reports keep you fully informed.

Amazon's New Rules & How We Handle Them

⚠️ The New Requirements

60-day window (Jan 2025): Claims must be filed within 60 days of the discrepancy. No exceptions, no appeals after the window closes.
Manufacturing cost (Mar 2025): Reimbursements based on your production cost, not selling price. Amazon's internal estimates are used if you don't provide accurate documentation.
Stricter documentation: Generic templates rejected more frequently. Each claim needs case-specific evidence.

✓ How Leviathan Sellers Complies

✓Daily auditing ensures no claim reaches day 59 without being filed.
✓Per-claim cost documentation — accurate, current COGS evidence for every individual claim.
✓Manual individual filing — every claim through official channels with tailored supporting documentation.
✓Active denial appeals — denied claims reviewed and re-filed. Most are not permanent.

📈You Have Never Run a Full Reconciliation Audit

Most sellers who have never audited find 6–18 months of accumulated discrepancies.

⚠️You Are Affected by the 2025 Policy Change

If filing claims without accurate manufacturing cost documentation since March 2025, you are receiving 20–50% less than Amazon owes you.

Performance-based — commission on recovered amounts only. Free audit with no obligation. We don't charge anything unless we recover money for you.
