1. Summary

On 29 September 2026, Wholesaler Y B.V. paid a deposit to "Example Supplier Ltd", a company that presents itself on the website example-supplier.example as a wholesaler in the United Kingdom. Since then the supplier has not responded. The investigation established the following facts:

  • The website's domain was registered 23 days before the first quotation (F1).
  • The registration number on the website and the invoice belongs, in the UK companies register, to a different company that was dissolved in 2019; the name Example Supplier Ltd does not appear in that register (F2).
  • The website shares texts and an analytics code with two other websites (F3).
  • The photo of Person A, named as director, is a stock photo (F4).
  • The invoice names a different payee for the account than the supplier (F5).
  • The bitcoin address on the payment page received payments from several senders; the funds were forwarded to an address attributed to a crypto service provider (F6).
  • No indication at all was found that Person B, a namesake in the Netherlands, is involved with the supplier (F7, exculpatory).

Not established: who runs the website, who controls the account and the bitcoin address, and whether Person A exists (chapter 6). This report contains facts and their reliability. Whether this is fraud, and which steps Wholesaler Y takes, is for the client and its lawyer to assess.

2. Research question

Which facts can be established from open sources and public registers about (a) the company presenting itself as Example Supplier Ltd and its website, (b) the persons named on the website and in the correspondence, and (c) the payment details on the invoice and the payment page?

Additional question from the client: is there a link between the supplier and Person B, an entrepreneur based in the Netherlands with the same name as the director named on the website?

3. Scope

  • Subject: the website example-supplier.example, the company and persons named on it, and the payment details on the quotation, the invoice and the payment page.
  • Period: online information from the registration of the domain (2 September 2026) up to and including the last capture (8 October 2026).
  • Sources: open sources and public registers, plus the documents supplied by the client (annex 3).
  • Outside the scope (not requested): contact with the persons involved and surveillance; NCRB carries out digital investigation only.
  • Not investigated, because they are not lawfully accessible to a private investigation agency: restricted profiles and closed groups, and bank, telecom or other protected data.

The scope was agreed with the client in advance in the investigation plan, at a fixed price. Any extension, for example to the two other websites in F3, first requires the client's approval.

4. Method and accountability

Sources used: the domain's registration data (RDAP), the web archive of the Internet Archive, the source code of the websites, search engines and reverse image search, the UK companies register (Companies House), the Dutch trade register (KvK) and public blockchain data, with an analysis tool for the attribution of addresses.

Capture. Every online source was captured with date and time (UTC), the full URL, a screenshot and, where possible, a copy of the complete page. A SHA-256 hash value was calculated for every captured file and every document supplied (annexes 1 and 3). If a file is later changed, even by a single character, the hash value no longer matches.

Confidence levels. Every finding is given one of three levels:

  • High established in an official register or a primary source (the original, the document supplied or the public blockchain), or confirmed by a second, independent source.
  • Medium one reliable source, not independently confirmed.
  • Low an indication from a source whose reliability is not established; not suitable as stand-alone support.

Facts and interpretation. Each finding first states the fact, with its source and capture. The interpretation below it is the investigator's assessment and is marked as such. Exculpatory findings are reported in the same way.

Lawfulness. The investigation was carried out under NCRB's Wpbr licence (POB 1737) and in accordance with the privacy code of conduct for private investigation agencies. Legal basis: the client's legitimate interest; the balancing of interests is recorded in the file. No fake accounts, no deception and no unauthorised access were used.

5. Findings

Seven findings, in the order of the research question. Each finding states the source, the time of capture, the annex and the confidence level.

F1 The domain was registered 23 days before the first quotation

Fact
According to the registration data (RDAP), example-supplier.example was registered on 2 September 2026. The first quotation to the client is dated 25 September 2026 (document D-01). The registrant details are masked by the registrar's privacy service. The website states "Your wholesale partner since 1998"; the web archive holds no version of the website from before September 2026.
Source
RDAP data of the domain; Internet Archive (Wayback Machine); website example-supplier.example
Captured
6 October 2026, 09:14 to 09:25 UTC
Annex
L-01 to L-03; S-01, S-02
Confidence
High for the registration date (RDAP)
Low for the absence of older archived versions: an indication, not proof

Interpretation (the investigator's assessment): A young domain is normal in itself: new companies have new websites. What is relevant is the contrast with the claim "since 1998".

F2 The registration number belongs to another, dissolved company

Fact
The website and the invoice (D-02) state "Company No. VB-000000". In the UK companies register that number belongs to Company Z Ltd (fictitious), dissolved in 2019, with a different name and address. No company named Example Supplier Ltd appears in the register.
Source
Companies House (UK companies register); website; invoice D-02
Captured
6 October 2026, 10:02 UTC
Annex
L-04; S-03
Confidence
High official register

Interpretation (the investigator's assessment): The registration stated does not support the existence of Example Supplier Ltd as a UK company. A typing or administrative error cannot be ruled out, but it does not explain why the name is missing from the register.

F3 The website shares texts and an analytics code with two other websites

Fact
The website's source code contains analytics code G-EXAMPLE. The same code appears in the source code of second-example.example and third-example.example. The texts on the "About us" page are identical on all three websites, apart from the company name.
Source
source code of the three websites; search engine
Captured
6 October 2026, 11:30 to 11:48 UTC
Annex
L-05 to L-07; S-04
Confidence
Medium one type of source; an analytics code and texts can also be copied

Interpretation (the investigator's assessment): The shared analytics code points to a common operator of the three websites, but that has not been established. The two other websites are outside the scope.

F4 The photo of the named director is a stock photo

Fact
The "Our team" page names Person A as director, with a portrait photo. A reverse image search leads to a stock photo website where the same photo has been offered since 2021 as a generic business photo, without a name.
Source
website ("Our team" page); reverse image search; stock photo website
Captured
7 October 2026, 08:40 and 08:52 UTC
Annex
L-08, L-09; S-05
Confidence
High the original is on the stock photo website with its publication date

Interpretation (the investigator's assessment): It is established that the photo does not show Person A. Whether Person A exists has not been established (chapter 6).

F5 The payee of the account has a different name

Fact
The invoice (D-02) requests payment to account XX00 EXAM 0000 0000 00 in the name of "Example Services", not in the name of Example Supplier Ltd.
Source
invoice D-02, supplied by the client
Captured
received 6 October 2026, 08:05 UTC
Annex
D-02
Confidence
High for what the invoice states; who holds the account was not investigated (chapter 6)

Interpretation (the investigator's assessment): A different payee also occurs with legitimate companies, for example with a parent company. It is, however, a point to raise with the client's bank.

F6 The bitcoin address received payments from several senders

Fact
Besides bank transfer, the payment page offers payment in bitcoin, to the address bc1q-example-fictitious. According to the public blockchain, that address received eleven payments from nine different addresses between 10 September and 5 October 2026. Each time, the funds were forwarded within three days to a single address that a blockchain analysis tool attributes to a crypto service provider.
Source
payment page of the website; public blockchain data; blockchain analysis tool (attribution)
Captured
7 October 2026, 13:15 and 13:31 UTC
Annex
L-10, L-11; S-06
Confidence
High for the transactions (public blockchain)
Medium for the attribution to the service provider (one source, not independently confirmed)

Interpretation (the investigator's assessment): Payments from several senders are consistent with several paying customers, but other explanations are possible. The report contains the transaction details needed for a police report.

F7 No link found with Person B Exculpatory

Fact
Person B has the same name as Person A and, according to the Dutch trade register, has owned a sole proprietorship in a different sector since 2015, with no establishment abroad. No reference to Person B, the sole proprietorship or its contact details appears on the three websites, in the source code, the domain data, the correspondence (D-03) or the payment details.
Source
Dutch trade register (KvK); websites and source code; documents D-01 to D-03
Captured
8 October 2026, 09:05 UTC
Annex
L-12; S-07
Confidence
High for what was checked

Interpretation (the investigator's assessment): The shared name is the only similarity found. On the name alone, there are no grounds to connect Person B with the supplier.

6. What could not be established

  • Who the registrant of the domain is: the registration data are masked and open sources give no answer.
  • Whether Person A exists, and who runs the websites.
  • Who holds the account and where the deposit went after receipt: bank data are not lawfully accessible to a private investigation agency.
  • Who controls the bitcoin address and who the customer behind the address at the crypto service provider is: that cannot be established from open sources.
  • Whether goods exist that could have been delivered.

These points are part of the outcome too. They show where open sources end, and which questions belong with the police, the public prosecutor or the client's lawyer.

7. Possible next steps

For consideration, without legal advice; that remains with the client's lawyer:

  • Report the payment to Wholesaler Y's bank, with this report.
  • File a police report; this report and its annexes can be attached.
  • Have the lawyer assess which legal steps are possible.
  • Keep the original e-mails, the quotation and the invoice unchanged; the hash values in annex 3 make it possible to verify later that they have not been altered.
  • Do not approach Person B, and do not name Person B in correspondence or a police report on the basis of the name alone (F7).
  • A follow-up phase can investigate the two other websites from F3, with its own scope and a fixed price or cost ceiling.
