Sending an invoice without a KvK number
Did a small job, sold a product, earned something on the side — and want to send a proper invoice for it, but you're not yet registered with the Dutch Chamber of Commerce (KvK)? Below: when this is allowed, when a receipt is enough, and how to get a clean invoice out the door once you are registered.
What you need to know
Private one-off? A receipt is often enough
If you incidentally sell something or do a service without being a business, you don't always need to send an invoice. A receipt or payment confirmation suffices.
From €1,800 turnover: time to register
If you regularly deliver services or products, or earn more than ~€1,800/year, the Dutch tax authority sees you as an entrepreneur. Then you must register with the KvK and charge VAT.

Frequently asked questions
Can I send an invoice without a KvK number?
Only if you're not yet an entrepreneur. For a one-off sale to a private individual, you can write a receipt with your name, date, description and amount. For business clients or regular income, you need a KvK number — otherwise it's officially not an "invoice" and the client cannot deduct VAT.
What's the difference between an invoice and a receipt?
An invoice is a formal payment request with mandatory data (KvK, VAT number, invoice number, VAT breakdown). A receipt is a confirmation of payment received. For the tax authority, only the invoice counts as a business document.
When am I officially an entrepreneur?
The tax authority looks at: hours invested, frequency of deliveries, external presentation (logo, website, price list) and turnover. No hard limit, but the rule of thumb: regular + independent + sustained = entrepreneur. Take the "entrepreneur test" on belastingdienst.nl.
Can I invoice as a side income next to my regular job?
Yes. Register with the KvK (sole proprietorship) and you can invoice alongside your day job. Income is declared separately in your annual income tax return.
What if I already worked without a KvK?
No disaster: write a receipt for the completed job. Then register if you expect to do more. For the tax authority, what you officially do counts from your registration date onwards.
