01 Why this

Why a fixed-fee check, not a free audit.

  • You keep 100% of what Amazon pays.

    The fee is USD 99, fixed. If Amazon pays out, nothing is taken from it.

  • Nobody touches your account.

    You download the reports yourself and send them. No password, no user permissions.

  • You get the deadlines, not just a total.

    Underpaid payments and claimable shipments come with the date their window closes, so you know what to do first.

02 What you get

Four findings in a short PDF.

  1. 01

    Underpaid, still disputable

    Reimbursements paid below your cost that are still inside the 60-day dispute window [source] [UK], with the date each one closes.

  2. 02

    Clawbacks to question

    Every reversal checked against the units Amazon actually found.

  3. 03

    A deadline map

    Inbound shipments still inside the 9-month claim window from delivery [source], ranked by size and urgency.

  4. 04

    Valued below your cost

    Items Amazon values below what they cost you, with the items to correct first.

03 How it works

Three steps. You never share access.

  1. 01

    Send four reports and your unit costs.

    Reimbursements, Inventory Ledger, Received Inventory and All Listings, downloaded from your own Seller Central. Plus a simple list of what each item cost you.

  2. 02

    I go through the reports line by line.

    Nothing is counted twice, and you see which cases are worth raising.

  3. 03

    You get a short PDF in 3 working days.

    Deadlines where they apply, and a short list of what to do first. The 3 days start when I have all four reports and your costs.

The step-by-step guide to the four downloads is sent once you get in touch.

04 Prices

Fixed prices. No percentage.

FBA Reimbursement Check

One marketplace, the last 9 months. Made for sellers who send inbound shipments to FBA every month.

USD 99

Shortage claims

For the shipments your check shortlists. Amazon decides each claim. The USD 99 check fee is credited if you go ahead within 14 days.

From USD 150 per 10 shipments
Start a check: USD 99

No login, no app connection. You file every claim yourself, so nothing goes to Amazon in your name without you seeing it.

05 Partners

For prep centres, accountants and agencies.

If your clients ask about missing units or short payouts, send them here.

  • Prep centres, 3PLs and accountants

    A referral fee for each client who goes ahead with a paid check.

  • Agencies

    Offer the check to your own clients, under your own name, at a partner rate.

Amazon ended its US FBA prep service on 1 January 2026 [source], so more seller stock now passes through prep centres first.

07 Questions

Before you send anything.

Do you need my login?

No. You send report downloads from your own Seller Central. I never ask for a password or account access.

What happens to my files?

They are used only for your check. Ask and I delete them.

How do I pay?

By invoice, once I have checked that your four reports are complete. Nothing to pay before that.

Do you take a percentage?

No. A fixed fee for the check, and fixed fees for any claims work after it.

Which marketplaces?

US, UK and EU Amazon marketplaces, one per check. Deadlines can differ by marketplace, and the report uses the rules for yours. Selling on more than one? Ask first and we agree the scope.

Can you guarantee money back?

No. Amazon decides every claim. The check shows what is worth pursuing and by when.

Tell me which marketplace you sell on, and I will send the guide to the four downloads. I am in Nairobi (UTC+3), so I overlap UK and EU working hours and US mornings.
