The problem

Amazon loses stock every day. Getting paid for it is the hard part.

Units go missing on the way in. Stock gets damaged in the warehouse. Customers are refunded and never send the item back. Each one is small, so nobody notices, and it adds up quietly in the background.

Even when you do spot it, claiming it is a job in itself. You dig through buried Seller Central menus, find the right case type, match transaction IDs, order IDs, SKUs and FNSKUs, and use the exact wording Amazon wants. Then you wait for a reply that reads like it was pasted, and reopen the case again.

So most sellers do one of two things. They give up on it, or they hand it to a recovery service that keeps a cut of everything Amazon pays back.

Why the usual options fall short

You either do the work yourself, or you pay a quarter of it away.

How it works

Hands-free claims, from your own Seller Central

  1. STK finds what's overdue. It spots lost, damaged and unreturned stock that Amazon hasn't paid you for, and lists every claim that's due.
  2. You click once. STK's browser extension opens Amazon's own help pages in your Seller Central and fills in the case for you: the right case type, the right IDs, the right wording.
  3. The case is raised and logged. STK records the case against the SKU, so you can see what was claimed and what was paid.
  4. Amazon pays you, not us. Reimbursements go straight to your Amazon account. We take no commission on any of it.

What you get

Money back, without the admin

Keep all of it

Every reimbursement Amazon pays lands in your account in full. No commission and no "platform fee".

Stop chasing cases

No more digging for transaction IDs or rewording a case for the third time. STK raises it for you.

See every claim

What was found, what was raised, what Amazon said and what it paid, all in one place against each SKU.

Your account, your control

Cases are raised from your own Seller Central session. You can see everything that's sent.

Part of your P&L

Reimbursements feed straight into your profit, so a lost unit you were paid for doesn't show as a loss.

Included in your plan

Reimbursements come with every SellerToolKit plan, alongside profit, VAT, stock and the optional repricer.

Your free trial

Try it on your own account for 14 days

Connect your Amazon account and STK checks your history for reimbursements that are due, and shows your real profit, fees and stock at the same time.

After 14 days it's £32.99 a month for up to 10,000 orders a month, with no commission on anything you recover. A recovery service charging 25% would take that much from a single £132 reimbursement.

What happens when you click

Two minutes to start

  1. Create your account. Email and password. No card.

  3. STK pulls in your orders, fees, stock and reimbursements. Your dashboard fills in as the data arrives.
  4. Add the browser extension and start raising the claims STK has found.

Questions sellers ask

Do you take a percentage of what I recover?

No. Reimbursements are paid by Amazon straight into your Amazon account. SellerToolKit is a flat monthly subscription and takes no commission.

Which marketplaces does it work on?

UK and EU marketplaces. Amazon has changed its reimbursement help pages for some US accounts, so case raising may not be available on every US account.

Will Amazon pay every claim?

No. Amazon decides each case. Some claims turn out not to be owed, for example where the customer's return was already credited. STK raises the case and records Amazon's answer, so you can see the outcome for each one.

Is it safe to connect my Amazon account?

You connect through Amazon's own authorisation page, which gives SellerToolKit access through Amazon's official Selling Partner API. We never see your Amazon password.

What does the browser extension do?

It opens Amazon's own help pages in your Seller Central and fills in the reimbursement case for a claim STK has found. It only works when you are signed in, and you can see each case it raises.

What happens after the 14 days?

Nothing is charged during the trial and we never ask for a card up front. If you want to carry on, you choose to subscribe. If you don't, you are not charged.

If I cancel, do I lose my data?

We keep your data for 8 days after you cancel, so you can come back without starting again.

P.S. Amazon has a time limit on most claims. Every week a lost or damaged unit goes unclaimed, it gets closer to being money you can never get back.

The trial costs nothing and takes two minutes. STK will show you what's due, raise the cases for you, and you keep everything Amazon pays.
