The listing card is an illustration of an ordinary product page. The ruling is a real run of this tool on that product, in Germany, priced from Amazon’s published 2026 rate card. That is the whole product — you describe something, it tells you whether to sell it.

Let’s imagine two products with exactly the same specifications. Same selling price, same weight, same box, same unit cost, sold in the same marketplace. On a spreadsheet they are the same business case.

Why the category changes everything

A category is not a label. It is the economics. It sets the referral fee Amazon deducts from every single sale, and those rates are not close to each other.

Amazon Device Accessories carries a referral fee of €11.21 on a €20.92 net price — 54% of the sale gone before fulfilment, storage, returns or the goods themselves are counted. Automotive and Powersports takes €3.73 for the identical box.

Same product, same cost, same customer. A different category, and the entire business case is a different one. That is the kind of thing this tool exists to catch — before a supplier is paid.

Where the €24.90 actually goes

Amazon Device Accessories — the full deduction stack, exactly as the tool prints it

What is left €0.07

Every line priced from Amazon’s published 2026 rate card. Nothing here is an estimate of a fee.

What you keep €0.07 0.3%

Every deduction from the €24.90 a customer pays, in proportion. The green sliver on the right is what reaches you: €0.07, or 0.3% of the price.

Every one of them returns the same set: the full profit and loss statement line by line, Amazon’s published referral rate for your exact category and whether its tier is a cliff or a marginal one, the price dead zones, seven risk checks grouped into five root causes, a go/no-go verdict with its mechanism named, and the 3P seller FBA and 1P vendor answers as two separate runs.

AMZ Verdict

Built by people who sell on Amazon, not by people who write about it

Wired to the rules of the game

Referral rates, fulfilment bands, storage, returns, duty, VAT and the dead zones between price tiers — all read from Amazon’s published rate cards and Seller Central pages. Every table is dated, sourced and carries its own confidence rating. Nothing is scraped and nothing is guessed.

Operator judgement, encoded

The seven checks, the price dead zones, the 2026 classification forks and the way failures are grouped by root cause come from running these businesses — and from the glossary and the frameworks in Selling on Amazon: 1P Vendor and 3P Seller, written by the person who built this.

Made to be called by an AI agent

Because it needs no account and no login, the whole tool is reachable from a single URL — so your assistant can run a verdict for you and hand back the reasoning. Tools that require an Amazon connection structurally cannot do this.

Where the judgement comes from

Based on marketplace expertise, vetted by Amazon FMCG industry veterans

The checks, the thresholds and the way failures are grouped draw on the frameworks set out in Selling on Amazon 1P Vendor and 3P Seller — Marketplace Wisdom for Professionals, ISBN 9798264313998 — among the sources this tool is built on. Giovanni Papini, who advises on AMZ Verdict, has spent over twelve years in e-commerce, digital marketing and Amazon marketplace management for established fast-moving consumer goods (FMCG) brands, across both the 3P seller FBA and 1P vendor sides.

The AI question, answered straight

Ask an AI what your Amazon fees are and it will guess. This does not.

A language model predicts what a fee probably looks like. It has no rate card in front of it, it cannot tell a cliff tier from a marginal one, and it will give you a different number tomorrow. AMZ Verdict reads Amazon’s published tables. The same product returns the same answer every time, and every line names the page it came from.

The right place for AI is on the other side: because this tool needs no login, your AI assistant can call it for you and get back a real verdict instead of an invented one.

This is the actual screen, not an illustration

Photographed from the live tool, on the product above. The verdict names the mechanism and never an outcome — and it answers the two questions separately, because “can I sell this myself” and “should Amazon buy it from me” are not the same question.

The AMZ Verdict tool showing a "Don’t" ruling for Amazon Device Accessories in Germany, and a separate 1P vendor recommendation. — The verdict as the tool prints it, on the run this page has been quoting throughout.

The second answer card, reading 1P vendor, with its reason. — And the second answer, underneath it. This product fails as a 3P seller FBA business and works as a 1P vendor supply — two questions, two answers.

Your figures stay in your browser. They are never sent to us, because there is nowhere to send them. The free tier keeps 3 saved products.

Pro & Business

One product is a decision. A range is a strategy.

Paid tiers judge every saved product at once and group what is failing by root cause across the range — because the same problem repeated six times is one fix, not six.

Three reasons this is worth buying

The numbers are Amazon’s, not ours

Every fee comes from the published rate cards, dated and sourced — including the two rulings above, which are real runs regenerated by a script that fails our build if they ever drift. Where something is assumed, the tool says so on the line.

It judges, it doesn’t just calculate

Seven checks, root-cause grouping and every price dead zone Amazon publishes — the marketplace dynamics an operator learns the expensive way, applied to your product in one pass.

You buy it once

A perpetual licence, not a subscription. The dataset current on the day you buy is frozen and stays yours. Renewal is optional, costs 40% of list, and never takes away the version you already own.

AMZ Verdict

The cheapest step in the entire venture

A licence is a one-off. The decision it informs commits your capital, your supplier terms and a year of your attention to a single product. The point of running the numbers first is that the answer arrives while changing your mind is still free.
