What is the situation
On 21 May 2026, KVK reported that 55 percent of entrepreneurs do not check a new business relation for a KVK number. One in five say they do not or hardly check new relations. KVK links that gap to fraud, non-payment and dealing with companies that do not exist. The real issue is wider than fraud. A KVK number is the entry point into the Handelsregister, the Dutch business register. A useful check also matches the legal or trade name, address, SBI activity code, signing authority, VAT ID, invoice identity and payment details. KVK also says 60 percent of Dutch companies change at least one registered detail each year, so counterparty files age quickly.
Analysis
For micro and small firms, this is a founder-control issue. The same person may sell, approve, book, pay and chase. If identity is weak, the exposure moves into contracts, VAT treatment, receivables, payables, insurance and recovery. Belastingdienst invoice rules place names, addresses, VAT ID and KVK number inside the ledger. A recent Rechtbank Limburg case shows why registered signing authority matters in disputes. Read the pressure by transaction exposure, not by sector averages. A valid KVK number does not prove solvency. With business confidence at minus 14.8 in early Q2 2026, credit control still belongs beside identity control.

Impact
H1
Before accepting a new customer, supplier or subcontractor, reconcile the offer, contract, invoice name, KVK entry, VAT ID and signer. If payment details change, pause and compare the request with the existing supplier file before money leaves the bank account.
H2
Treat onboarding as the start, not the end. Refresh material counterparties when contracts renew, ownership changes, addresses move, activity changes or exposure grows. A clean file from six months ago can already be stale in a register where many companies change details each year.
H3
The same discipline applies inward. Keep your own Handelsregister data, trade names, address, activity and functionaries current. Banks, municipalities, insurers and counterparties use registered facts. Stale own data can slow financing, permits, contracts and claims.
Daily operational takeaway
For the next new or changed counterparty, create a one-page identity file before contract, delivery, invoice treatment or first payment.
