Where we start
Sample. The real one runs on your exports.
Brands we've worked with
The problem
The decisions that cost you most get made without you.
Four examples, among the most common. The list isn't closed, and the order changes with every account.
Amazon doesn't handle every supplier the same way. Above a certain volume there is a buyer, shared across a lot of brands and often across the whole of Europe. Below it there is no buyer, just a form. Either way, your German, Italian and Spanish accounts each run their own life, and nobody reads them together.
01
“Money comes off our invoices and we've never been shown why.”
Amazon deducts first, then gives you thirty days to prove it was wrong. Document by document, market by market.
What does that add up to across your last twelve months, all countries together? If the number doesn't come straight away, that's already an answer.

02
“What they pay us doesn't match what we invoiced.”
Amazon settles the invoice, then raises a negative one for the gap found at receiving. The hole turns up in cash later, sometimes after the dispute window has closed.
Who on your side reconciles the order, the shipment, the invoice and the remittance?

03
“Overnight, nothing. The product was selling.”
Amazon expects an acknowledgement within twenty-four hours, and any line left out is rejected by default. The code your order desk sends back feeds the buying decision: a sustained unavailability code suspends ordering on the item.
Over the last six months, how many orders did you turn down, and with which code?

04
“We pay percentages every month for services we've never seen.”
Marketing allowances, programme fees, damage allowance. Terms get negotiated once and deducted twelve times, across five markets.

We answer those four on your exports, not on a study. Fifteen minutes.
Book an auditThe method
No verdict in fifteen minutes.
You can't judge an account from the outside. We get the data first, then come back with what it says: findings, not a pitch. Everything before the engagement is free.
Start with the teardownIt's free because we'd rather show the work than sell you on it. An audit that turns up nothing goes nowhere, which filters our pipeline as much as yours.
01
Free teardown
Fifteen minutes on your public Amazon presence. Two or three concrete findings, on screen. We show you rather than tell you.
02
R1 — questions & data
The questions that matter, and an agreement on what you share. Your data stays yours, with an NDA before anything moves if you want one. No data, no diagnosis.
03
Analysis
We go through the numbers ourselves: where revenue is leaking, what each leak costs, and the order to fix them in.
04
R2 — findings & proposal
We hand back everything we found. It's yours either way. If you want us on the fixes, that's where we scope it.
The scope
1P, 3P, or both.
Vendor Central is where we're strongest, and where real expertise is hardest to find. But no account lives in isolation — we run 1P and 3P with the same rigor.
Core
Amazon Vendor · 1P
You sell to Amazon and Amazon resells. Deductions, availability, the annual negotiation, ranking. This is where the biggest leaks sit, and where we are most useful.

Amazon Seller · 3P
You sell direct. Buy box, advertising, catalogue, net margin per item. Run on its own, or alongside a Vendor account.

Book an auditThe operators
Mahrez, and the team behind him.
Founder — brand side
Mahrez
Twenty years in e-commerce, fifteen of them on Amazon: Seller and Vendor Central, FBA, Ads. Operating since 2011, not theorising about it. He has run the channel for established brands from the inside, answerable for the same numbers he now audits.
The rest of the team — Amazon side
A senior team
Alongside him, senior operators who spent years inside Amazon, on international brands across several categories. They know first-hand how Vendor decisions actually get made, what an AVN or a JBP can really move, and where an account quietly stalls. No juniors, nothing subcontracted: every account stays with people who have run one before.
Fifteen years operating on Amazon between us, and a seat on both sides of the table.
The fit
We say no more often than we say yes.
You can't judge an Amazon account from the outside. It takes history, exports, and someone on your side who can make the call. Here's what we look at before we start.
- Model
- Vendor 1P, alone or alongside Seller
- Markets
- Amazon's European stores, read together
01
A 1P account that's been running for years
It produces data every day. Nobody has the time to read it. That's where we find the most.
02
A retail brand arriving on Amazon
Physical distribution is already there. The Amazon channel gets built, not improvised between other jobs.
03
An opening into new European markets
The model works in one country. Copying it across doesn't: neither the competition nor the seasonality follows.
04
A 1P account that's slipping
Volumes down, items going quiet, terms tightening. Here the clock matters more than anything.
This isn't for you if
- You're starting out on Amazon. No history, no diagnosis. There is nothing to read on a blank page.
- You want advertising and nothing else. We look at what happens before the sale first. The problem is rarely in the ads.
- You can't get your data out. Without exports there are only opinions, and ours are worth no more than yours.
- Nobody on your side can make the call. What we find cuts across supply chain, finance and commercial at once.
If your account doesn't fit, we say so at the teardown, not three meetings in. And we never promise to talk to an Amazon contact who doesn't exist.
Going further
Three ways to work together.
The audit commits you to nothing. If the findings warrant it, we carry on at whatever intensity the account needs, on Vendor, Seller, or both.
One-off intervention
TargetedAn expert day, or a deep dive on one specific issue, when a single fix is enough to move the number.
Monthly retainer
ContinuousWe stay on the account month to month: optimization, watching the penalties, and steering the negotiation.
Full management
DelegatedWe run the account end to end, scoped to fit. You get your time back; we keep our hands on the numbers.
Senior operators on every account, nothing offshored. Scope and budget are set at R2, once the findings are in.
Common questions
What people ask us most.
What makes you different from other Amazon agencies?
Two things. Mahrez worked brand-side; the rest of the team worked inside Amazon. Having both reads in the room is rare, and it's exactly where most Vendor blind spots sit. Beyond that, we stay small and senior, with nothing subcontracted: the person you talk to is the person working on your account.
Do you talk to our Vendor Manager?
Only if there is one. For part of this segment Amazon no longer assigns a dedicated buyer: requests go through a form and decisions are made by systems. An agency promising to call your Vendor Manager is sometimes promising something that doesn't exist. We check whether you have one first, then adapt. With no counterpart, the lever stops being the relationship and becomes your data and your contract.
Do you work on Vendor (1P) or Seller (3P)?
Both, to the same standard. Vendor Central is where we're strongest, and where the expertise is hardest to find. Seller Central runs on its own, or alongside a Vendor account.
What exactly is a "teardown"?
Fifteen minutes going through your public Amazon presence: listings, positioning, the signals anyone can read from outside. We show you two or three concrete findings on screen. Nothing to prepare, no access to hand over, and it commits you to nothing.
Why is the audit free?
Because we'd rather show how we work than describe it. An audit that turns up nothing goes nowhere, which filters our pipeline as much as yours and saves everyone the time.
How long before we see results?
It depends entirely on what the audit turns up. Some fixes show within weeks: disputing chargebacks, closing avoidable stockouts. Others, like organic ranking, play out over months. You get a realistic timeframe at R2, once the findings are in, never before.
Which European markets do you cover?
All European Amazon marketplaces. Each country has its own dynamics, from competition to seasonality to buying behavior, and a strategy that works in one market doesn't transfer mechanically to the next.
