WhatsApp: the quickest way to reach your bookkeeper
For short questions, WhatsApp is the fastest channel, with a reply usually within an hour. You can send a photo of a letter, a quick question about an invoice or a heads-up about a large purchase. For longer questions or documents, email works well. If you call and Michiel is busy with returns, he calls back later the same day where possible.
Location
The accountant's office in the Dapperbuurt
Finance People is based at Commelinstraat 44 in the Dapperbuurt, Amsterdam Oost, close to the Dappermarkt. There is no waiting room, and most work is done remotely, so please arrange a meeting in advance rather than dropping by. Clients come from across the city, as described on the page about Finance People as an accountant for creatives throughout Amsterdam.
New clients
Becoming a client of this accountant for creatives from 2027
The client list for 2026 is full, so a general message will not get you a place this year. To become a client from 2027, use the sign-up form for the 2027 waitlist. Michiel contacts people in order of sign-up when a place opens. Before you sign up, it may help to read how working together is organised and to learn a little about the accountant you would work with.
Clients
For existing clients: sending bookkeeping documents and questions
What to send by WhatsApp and what by email
If you are already a client, a few habits keep things quick. Send short questions and photos of letters by WhatsApp, so Michiel can react between other work. Send invoices, receipts and bank statements in the way you agreed at the start, so they end up in the right place in your bookkeeping. Use email for anything that needs a longer explanation or several attachments, such as an overview of a large project or questions about your income tax return.
Tell Michiel early about changes that affect your tax
Let Michiel know early about changes that affect your taxes: a new job next to your freelance work, a big equipment purchase, plans to move abroad or a change in the way you sell your work. A message before the change is almost always more useful than an explanation afterwards, because there is still room to choose the best approach.
First check
Before you send a tax question
Many general questions about Dutch tax, such as what a zzp'er is or how the KvK works, are answered on the FAQ page about Dutch tax for creatives. That may save you a wait, and it helps Michiel spend his time on questions that need a personal answer.

What is the fastest way to reach Finance People?
The fastest way to reach Finance People is WhatsApp on +31 6 15533374, where Michiel usually replies within an hour. Email to info@finance-people.nl works well for longer questions and documents. Phone calls are possible too, but may be returned later in the day.
Can I contact Michiel if I am not a client yet?
Yes, you can contact Michiel if you are not a client yet, for example to ask whether Finance People fits your situation. Keep in mind that no new clients are taken on in 2026. To become a client from 2027, sign up on the waitlist rather than sending a general message.
Which email address does Finance People use?
Finance People uses the email address info@finance-people.nl. Messages to this address are read by Michiel Terwindt himself. For documents such as invoices and receipts, the way of sending is agreed at the start of the collaboration, but email is always a good fallback.
Is Michiel Terwindt on LinkedIn?
Yes, Michiel Terwindt is on LinkedIn, where his profile shows his career in finance since 1999. He also has a personal website at michielterwindt.nl. For questions about your taxes or bookkeeping, WhatsApp or email is quicker than a LinkedIn message.
Can I send Finance People a WhatsApp message in English?
Yes, you can send Finance People a WhatsApp message in English. Michiel works in both English and Dutch and replies in the language you write in. Photos of letters from the Belastingdienst in Dutch are fine too; he explains them in English.
Where is the Dapperbuurt in Amsterdam?
The Dapperbuurt is a neighbourhood in Amsterdam Oost, east of the city centre and built around the Dappermarkt, one of the city's best known street markets. Finance People's office at Commelinstraat 44 is a few steps from the market.
Can I just walk into the Finance People office?
Walking into the Finance People office without an appointment is not recommended, because there is no reception and Michiel often works remotely or with clients. Send a WhatsApp or email first, and a meeting at Commelinstraat 44 can be arranged when it is useful.
What should I include in my first message to Finance People?
In your first message to Finance People, include your profession, how long you have been freelancing, roughly which income streams you have and what you need help with. If it is about becoming a client, mention that you would like to start in 2027 or use the waitlist form.
Working with Michiel in 2027?
Finance People works with a limited number of makers, so everyone gets Michiel himself on the line. Put your name on the waitlist and you will hear as soon as there is room.
