Practical verification of the Dutch contractor before the contract: KVK register, signing authority, VAT number in VIES, references, finances and red flags.
The first good conversation is not enough to assess the credibility of a contractor. A professional website and a concrete declaration of cooperation do not replace checking the data. This applies to large orders, distribution, agencies, and subcontractors.
If the company is still deciding on the direction of its expansion, it is first worth assessing:, is the Netherlands a good market for a Polish company?. The verification of the counterparty begins later, when a specific entity appears on the table and there is a real possibility of cooperation.
I have been working in the Netherlands for 16 years and I see that many risks can be identified before signing a contract. It’s not about conducting an investigation. A structured verification is needed: registration, representation, VAT status, consistency of information, references and the company’s financial health. Together, these elements form the picture on which a business decision can be based.
The list below is intended for practical and informational purposes only. It is not legal, tax or financial advice. When entering into a contract of a significant value, with unusual terms or if you have any questions regarding liability, it is advisable to engage the services of an appropriate advisor.
Start with the KVK register
The KVK, or Kamer van Koophandel, maintains the Dutch business register Handelsregister. The official KVK material indicates that the register allows determining who is conducting the conversation, who can sign on behalf of the company, and whether the company is in bankruptcy. The current copy provides more information than simply searching for the name online.[1]
The reply should primarily compare:
- the full legal name and trade name;
- KVK number;
- legal form;
- address of the registered office and possible branches;
- the date of registration;
- description of the activity and SBI codes;
- the names of the persons representing the company;
- the method of representation and any limitations on the scope of the power of attorney.
The mere presence in the KVK does not confirm that the company is a good partner. However, it confirms its registered identity and provides a reference point for further verification. A company that has recently been registered deserves special attention; its representatives cite a long history as the reason for this. The explanation may be simple, such as a change in legal form, but it is worth asking about it.
Check who has the right to sign the contract
In practice, this is one of the points that are most often overlooked. The person conducting the negotiations cannot always independently enter into obligations on behalf of the company. The register can indicate single-person representation, joint representation, or limited power of attorney to a specific amount. According to the KVK, the persons authorized to sign documents and contracts should be disclosed in the register, and incorrect data can lead to a dispute over the validity of the signed contract.[1]
Therefore, before signing, it is necessary to check the name, function, and scope of the authorization. If two signatures are required, the one signed under the agreement does not resolve the matter. If the document is to be signed by an agent who is not visible in the current copy, or if the agent’s powers raise doubts, it is necessary to request a power of attorney document and consult its content with a lawyer.
Verify the VAT number in VIES
Next step in intra-EU transactions is VIES. This is a system of the European Commission that checks data collected from national VAT databases. The result shows whether a given number is valid for intra-EU transactions.[2]
The verification should be carried out well before the first invoice, and periodically during longer cooperation as well. It is necessary to keep a confirmation of the result along with the date. The European Commission explicitly recommends storing the verification record in case of tax inspection.[2]
An „invalid” result does not always mean a fictitious company. It may indicate that the number does not exist, has not been activated for intra-EU transactions, or the registration has not yet been completed. Data in databases do not always update immediately.[2] Such a result requires clarification before the transaction is executed, not an automatic accusation of the counterparty. In an urgent matter or persistent discrepancies, the appropriate address is the tax administration or tax advisor.
Compare all the data, not just the numbers
Credibility is often seen in the consistency of details. The legal name from the KVK should match the name on the contract and invoice. The VAT number, KVK number, email domain, bank account, and address should point to the same entity or have a clear connection.
It is worth compiling:
- copy of the KVK approval letter with the draft agreement and an email confirmation;
- registered address with the address on the website and on the invoice;
- the name of the account recipient with the name of the counterparty;
- the broadcaster's domain with the company's official domain;
- the scope of activity with an offer submitted to a Polish company;
- persons listed on the website or LinkedIn with representation disclosed in the KVK.
A single difference does not determine the risk. A Dutch company can use several trade names, belong to a group, or handle billing through another entity. What matters is a clear, documented explanation. If it is not known which company is selling, which is signing the contract, and which is accepting payment, the process must be stopped until the data is sorted out.
Ask for references that can be verified
A reference is only valuable if it comes from a real client or partner and relates to a similar type of collaboration. The list of logos in the presentation alone does not provide such certainty. It is better to ask for two or three contacts with whom you can have a brief conversation, of course with their consent.
Questions about documents and previous projects should be included right away. the first conversation with a partner in the Netherlands. The response to a factual request for confirmation of data also says a lot about the readiness for transparent cooperation.
During the reference discussion, specific topics are useful: timeliness, compliance with agreements, the way problems are handled, the quality of communication, and billing. It is also worth determining the scope and duration of the cooperation. A one-time small order from several years ago is not equivalent to an ongoing relationship with a similar profile to the planned project.
The absence of references does not necessarily disqualify a young company. However, it should affect the way the collaboration begins: a smaller scope of the pilot project, a shorter billing period, no high upfront payment, or additional safeguards agreed upon with the advisor.
Evaluate the company's condition and its ability to fulfill the contract
The financial condition of a counterpart is more than just revenue. Things like liquidity, indebtedness, the timeliness of reporting, changes in management, turnover of contact persons, and operational capability are also important. The range of publicly available data depends on the legal form and size of the company, so the lack of an extensive financial report is not always a reason for suspicion.
Available reports, sales reports, information about proceedings and the history of registration changes can be used for evaluation. For a larger contract, it is worth checking whether the company’s scale matches the declarations: number of employees, warehouse, service facilities, insurance, or production capacity. A good practice is to start with a trial order and establish measurable stages of execution.
Not every partner has to be big. A small company can be solid and specialized. The problem starts when it promises a scope that it cannot reliably handle, and on request for data it answers with generalities.
Red flags before cooperation
Caution is advised when several of the following signs appear:
- pressure to sign immediately or pay a high advance;
- payment to an individual or entity not mentioned in the contract;
- contact only from a free email address;
- discrepancies between the KVK, VIES, the contract, the party and the invoice;
- an unclear answer to the question of who is the party to the contract;
- signature of the person without visible authorization;
- Frequent changes in the name, address, management, or account just before payment;
- refusal to provide basic documents or consent to check references;
- an offer that is clearly out of line with market conditions without any tangible justification;
- the rush to conclude the agreement combined with a request to maintain non-standard arrangements outside the contract.
One red flag may be due to organizational chaos. Several red flags at once change the risk assessment. Then it is better to slow down, ask for the documents, and not make any payments until the matter is resolved.
Simple order of verification
First, you need to download the current KVK data and determine the appropriate entity. Then check the representation, the VAT number in VIES, and the consistency of the data on all documents. The next step is a reference discussion and an assessment of the company’s condition. At the end, the commercial terms should correspond to the recognized risk: the scope of the pilot, the schedule, payments, deliveries, and responsibilities must be clearly stated.
The scope of the control also depends on whether the conversation concerns distribution, representation, or another form of partnership. I compare these roles in the article. Business partner in the Netherlands: distributor, representation or networking?.
Verification does not provide a hundred percent guarantee. However, it allows you to separate ordinary administrative shortcomings from situations where a partner avoids responding, documents, and accountability. This is also a good test of the quality of cooperation. A reliable company usually understands that the other party has its own security procedures.
FAQ
Is the KVK number enough to consider a company reliable?
No. The KVK number confirms the registration and allows you to verify the entity's data. The assessment should be supplemented by representation, VIES, document consistency, references, and operational or financial status.
How to check if a person can sign a contract for a Dutch company?
It is necessary to check the representation method in the current KVK report. Attention should be paid to the total representation, the limits of the power of attorney and other restrictions. In case of any ambiguity, verification of the power of attorney by a lawyer is necessary.
What to do when VIES shows the status „invalid”?
First, repeat the verification and ask the counterparty to explain. The status may indicate a missing number, a lack of activation for EU transactions, or an unfinished registration.[2] Before applying a specific VAT settlement, it is worth consulting a tax expert.
Is it possible to check a Dutch company without a paid report?
Yes, the basic checks can be started with the KVK, VIES, company website, documents, and references. However, for larger contract values, a paid sales report or the support of a specialist can provide information that cannot be found in free sources.
