Our Services
Choose Your Starting Point
Each service is designed to work standalone or as part of a complete FBA management solution. Most clients start with the free audit.
Leviathan Recon
Our self-serve inventory reconciliation platform. You export your own Amazon reports and upload them; Recon rebuilds your unit ledger per FNSKU and shows you where Amazon's balance and yours stop agreeing — with the rows behind the figures there to open.
✓Your unit ledger rebuilt per FNSKU from your own reports
✓Variances flagged against Amazon's own ending balance
✓Separate reconciliations including shipments, removals, returns, transfers and adjustments
✓Sixteen report types supported — four are enough to start
✓Duplicate rows detected and skipped, so re-uploading doesn't double-count
✓Fifteen raw tables in Data Explorer, searchable and CSV-exportable
✓Your own database rather than a shared table, in a workspace your admin brands with your company name and logo
✓Admin, Vendor and Viewer roles, with an audit log of changes
Pricing: Free for 14 days with no card on file. Access afterwards is quoted on your account size and the marketplaces you sell in, and we send you the numbers before anything starts.
Daily auditing of your Seller Central transactions. We identify discrepancies, document them, and file claims by hand inside the 60-day window — with the manufacturing-cost documentation Amazon's 2025 policy requires.

✓Fee overcharge identification & refiling
✓Inbound shipment shortfall claims
✓Removal & disposal error recovery
✓Manufacturing cost documentation

Request a free audit and upload your reports. Your audit is prepared from those files: most are returned within a few business days of upload.
01
Fill in the Audit Form
Takes 2 minutes. Tell us about your account and what you need help with.
02
Upload Your Reports
Export your standard reports from Seller Central and upload them. The audit and the claim work both run on those files, so you can see what's recoverable before anything else is agreed. Anything beyond that is agreed with you in writing first.
03
Receive Your Audit
Your audit is prepared from the reports you upload: most are returned within a few business days of upload, setting out the recoverable discrepancies it surfaced and what each one would need to file.
04
We Start Recovering
Upon your approval, we begin filing claims immediately — every day, before the 60-day window expires.

What Makes Our Amazon FBA Services Different
Personal Service, Not Automation
Accounts are worked by hand rather than queued through a filing bot. Claims are prepared one at a time, and recommendations are written against your own account's numbers instead of generated from a template.
US, UK and India Expertise
We understand specific requirements of each Amazon marketplace. India-based sellers expanding internationally and international sellers entering Amazon India are both types of clients we have supported.
Manual Filing, Official Channels
Claims are prepared and submitted by hand through Amazon's own case system, against the documentation and filing windows Amazon publishes.
A Complete Amazon FBA Service Stack — and How the Pieces Fit
Leviathan Sellers is built around a simple idea: the three things that decide whether an Amazon FBA business is profitable — recovering money Amazon wrongly keeps, keeping the account operationally healthy, and choosing products with real margin — are usually handled in isolation, badly, or not at all. We treat them as one connected system. You can engage any single service, but they are designed to reinforce each other, and most sellers see the biggest gains when at least two run together.
The entry point is almost always a free audit. It costs nothing, carries no obligation, and turns vague worry (“am I leaving money on the table?”) into a concrete number you can act on.
Recon, Recovery, Management and Research — What Each Solves
Leviathan Recon is the self-serve lane, and the only one you run yourself. You upload the Amazon reports you already export, and the platform rebuilds your unit ledger per FNSKU so you can see where Amazon's balance and yours stop agreeing — before anyone files anything.
Our FBA reimbursement recovery service is the financial-recovery lane. Amazon's warehouses process billions of units a year and make mistakes at scale — lost and damaged inventory, mis-charged fees, return discrepancies. Since January 2025 you have just 60 days to claim each one, and since March 2025 every claim needs manufacturing-cost documentation. We audit daily and file each claim manually so nothing expires.
Our Amazon FBA account management service is the prevention lane. It keeps your Inventory Performance Index above the thresholds that trigger storage restrictions, resolves listing suppressions before they cost sales, and plans replenishment so you avoid both stockouts and excess-storage fees. And our Amazon product research service is the growth lane — finding products whose unit economics survive Amazon's 2025–2026 fee structure, validated in our free FBA calculator before you commit a purchase order.
Almost every seller should start with the free reconciliation audit. It is no-obligation, prepared from the reports you upload, and tells you how much recoverable money is sitting in your account right now. Most are returned within a few business days of upload. From there, FBA account management makes sense if your IPI, storage limits, or listing health need ongoing attention, and product research fits when you are ready to add new SKUs. Many clients run reconciliation plus account management together.
Yes. Each service stands alone. Reimbursement recovery is performance-based, so you can run it with no fixed cost. Account management and product research are separate engagements priced on scope. There is no requirement to bundle — though they reinforce each other, because recovered cash, a healthy account, and well-chosen products compound.
Leviathan Recon starts with a free 14-day trial and no card on file; access afterwards is quoted on your account size and the marketplaces you sell in, and we send you the numbers before anything starts. Reimbursement recovery is commission-only: you pay a percentage of what we actually recover, and nothing if we recover nothing. FBA account management is a transparent monthly retainer based on account size, SKU count, and marketplaces covered. Product research is priced per project or as a monthly retainer depending on scope. The done-for-you services begin with a free audit or consultation.
Yes. We actively support sellers on Amazon US, UK, India and Canada, as well as EU marketplaces and Amazon Australia, with documentation and fee logic specific to each marketplace. We are based in Vadodara, India, and work with both India-based sellers expanding internationally and international sellers entering Amazon India.
Leviathan Recon runs on reports you export yourself: there is no API connection to your account and no credential of yours for Recon to hold. Recon reads the files you upload. It cannot place orders, change listings, move funds, or act in your account.
The same reports, and nothing further. The audit, the manufacturing-cost documentation and the claim filing all run on the files you export and upload, so the service works from the same uploads Leviathan Recon does. Anything beyond that is agreed with you in writing first.
We work to Amazon's published policies. Reimbursement claims are prepared and filed by hand through Amazon's own case system, with the manufacturing-cost documentation its 2025 policy requires, and we don't use bulk-automation filing or grey-hat tools.
Not Sure Which Service You Need?
Start with the free audit. We'll tell you exactly what's recoverable and which services would make the biggest impact on your account.
