What happens at incorporation
The notary registers the new BV right after the deed is signed. For founders, this step involves zero extra signatures. This also applies when you set up the company from abroad. The KVK issues the KVK number, which is the public company ID. The company also gets an RSIN, the number used in government systems. The KVK records the directors, their powers to represent the company and the registered address. It records the activity codes of the company as well. The registration fee is a one-time amount of a few tens of euros. This is the cheapest step of the whole formation.
What is on the KVK extract
Banks, platforms, customers and suppliers all use the same extract. It has the company details, the directors and who may sign, the address and the activities. This is the public record of your company, so check the details once at formation. Check that the powers to represent the company are correct and that the activity codes match what the company does. Also check that the address is set up properly. The activity codes are also used for sector classifications, for example in the pension check. For the address, see the registered office rules. The UBO register is a separate register with its own access rules. See who sees what in the UBO register.
You can set up the company by power of attorney, from any country. This usually happens within one week once all documents are complete. See setting up a BV in the Netherlands from abroad.
Changes you report after registration
File changes promptly: new directors, address relocates, activity shifts. Most of these are simple online filings, and most are free. Keeping the extract accurate makes every later check easier, because banks and clients rely on it. It is the cheapest compliance habit a company has: the practical hub.
