Where reviews come from
A rating on its own says very little. Four point nine from thirty voices is not the same as four point nine from five thousand, and a review anyone may write is not the same as one a platform asks for after a piece of business. This page explains the difference and sets out where our own figures come from.
Two kinds of source
Invited
The platform contacts the customer after a piece of business and asks for a review. The voice is tied to a transaction. Anyone who never dealt with the firm never receives an invitation.
That makes such reviews traceable. It does not automatically make them more honest, but it makes them accountable.
Open
Anyone holding an account with the platform may write, with no proof and no transaction behind it. Including someone who only rang up once, only read a quote, or was never a customer at all.
That makes such reviews more immediate and often blunter. It also means a figure can contain voices with no contract behind them.
Both are lawful and both have their place. It only becomes a problem when an open source is presented as a verified customer voice.
Our figures, broken down
| Platform | Reviews | Kind |
|---|---|---|
| Kundennote | 2,541 | invitation after a transaction |
| Ausgezeichnet.org | 1,796 | invitation after a transaction |
| 685 | open to anyone |
5,027 reviews in total, averaging 4.98 out of 5, as at 30 September 2026. All three are German-language platforms, which is where most of our customers are. The totals are aggregated by Trustami, where the sum can be checked.
We spell this out because the open share belongs in the picture: part of our figure comes from a platform that verifies nobody. Anyone reading our rating should know what is inside it.
How we choose what is shown
The individual voices on our German review page are sorted by date, newest first, and displayed in that order. The star rating plays no part. No line in the software filters by it, and nobody edits by hand: a daily job fetches the texts from the platform unchanged, and the next job overwrites any manual edit.
The pool currently holds 13 individual voices, 13 from AUSGEZEICHNET.org. Wording, stars, name and date are taken as they stand. Nothing is shortened or smoothed over, because an edited customer voice would be an invented one.
It is still a selection, and that should be said plainly: not every voice, but the most recent ones. The criterion simply has nothing to do with the rating.
Six questions for any rating
- Whose figure is it? A rating always belongs to one company and often to one branch, not to a group and not to a brand.
- Over what period? A rating drawn from twenty years hides how things are running today.
- Was anyone allowed to write? Or only those invited after a piece of business.
- Are the voices shown a selection? And if so, on what basis. When every voice on display carries top marks, that is rarely chance.
- Is there a link to the source? Without one, neither the count nor the average can be checked, and the poor reviews stay out of sight.
- Which product do they concern? Someone who chartered a yacht for a fortnight had a different experience from an owner insuring their own boat.
The rules behind this
Since 2022 this has been written into European consumer law. Directive (EU) 2019/2161, which amended the Unfair Commercial Practices Directive, obliges a trader who advertises with consumer reviews to state whether and how it ensures those reviews come from people who actually used the product or service. That is a duty to inform, not a ban.
The stricter rule sits in the blacklist of practices that are unfair in all circumstances: claiming that reviews come from genuine users without taking reasonable and proportionate steps to verify it. Every member state has transposed both into national law; NAMMERT is a German undertaking and is bound by the German implementation. That is why the word verified no longer sits above our figures. The origin does.
Questions and answers
Frequently asked
What is the difference between an invited and an open review?
An invited review is one the platform asks for after a transaction, so the voice is tied to an actual piece of business. An open review can be written by anyone with an account, including someone who was never a customer. Both are lawful and both have their value, but they are two different things.
Does Google check whether someone really was a customer?
No. A Google account is enough. No proof of purchase is asked for and no transaction is matched to the review.
How does NAMMERT decide which voices appear on the site?
By date, newest first. The star rating plays no part in the selection; there is no line in the software that filters by it. Critical voices therefore sit among the others.
What does a company have to disclose about its reviews?
Under EU consumer law, a trader who advertises with consumer reviews must state whether and how it makes sure they come from people who actually used the product or service. Claiming that reviews are from genuine users without taking reasonable and proportionate steps to check is prohibited outright.
