Or start free, with no card
The free tier is the whole product — the full profit and loss statement, all seven checks and the verdict — on 3 saved products in one marketplace. Not a preview, and no trial clock. Move up when you outgrow the room, not when a timer runs out.
Prices in USD. Every paid tier covers all 11 marketplaces and every published category. Payment and invoicing are handled by Lemon Squeezy as merchant of record.
The conditions, in full
All of them. There is no clause below this list.
- Buy once, keep it A perpetual licence. No subscription, no monthly charge, no seat count, and no month where the tool stops working because a card expired.
- The dataset is frozen at your purchase date Fee tables, referral rates, VAT and duty refresh once a year, effective 1 February. Whichever version is current when you buy is yours permanently.
- No expiry and no update window Skip a year, skip five — the version you own keeps working exactly as it did on day one. An older dataset is something you keep, never something you lose.
- Three devices per licence Activations can be released and moved to another machine.
- All 11 marketplaces on every paid plan Six are fully calibrated. The other five are fee-complete, and the tool says so next to the verdict rather than in a footnote.
- No Amazon account, ever Nothing to connect and nothing to authorise, so an answer arrives before you have a listing, a supplier or a single unit.
- Invoiced by Lemon Squeezy They act as merchant of record, so VAT and invoicing are handled properly wherever you are.
Renewal is optional and only ever adds. It costs 40% of the list price and buys the following year’s data and that year’s features. It never removes or downgrades what you already own, and if you lapse, a single renewal brings you back to the current year however many years you skipped.
Everything in the plans, side by side
Every plan — the free one included — gives the whole engine on one product: the full profit and loss statement, all seven checks, the verdict, and the Excel round trip. The paid plans add ways of judging more than one product at a time, which is where a range stops being a list and starts being a strategy.

Questions people ask before buying
Is this really not a subscription?
No recurring charge of any kind. You pay once and the version you bought keeps working. Renewal exists, costs 40% of list, and is entirely optional — it buys the next year’s data, it does not keep the software alive.
What happens if I do not renew?
Nothing. The dataset you bought is frozen and stays yours permanently. You simply do not receive the following year’s fee tables or that year’s features until you choose to renew.
Do I need to connect my Amazon account?
No, and you cannot. The tool never asks for an account, a token or a listing. That is why it can answer before you have a product on sale at all — and why your figures never leave your browser.
How many devices does a licence cover?
Three activations per licence key. You can release an activation and move it to another machine.
Which marketplaces are covered?
All 11. Six are fully calibrated; the other five are fee-complete, which means the fees are published and priced but the benchmarks behind the verdict are not calibrated for that market — and the tool says so next to the verdict rather than in a footnote.
Can I try it before paying?
Yes. The free tier is the whole product on 3 saved products in one marketplace — not a limited preview. No card and no trial clock.
Start with the free tier
It is the same engine, the same profit and loss statement and the same verdict. If it does not change how you look at a product, there is nothing to buy.
