What our clients
say about Suijkerbuijk + Co

We highly appreciate the service provided by Willem. His forward-thinking and excellent communication are part of his characteristics. Furthermore, Willem has set up our BV/Holding structure very well and always thinks in terms of solutions instead of problems. In addition to being an accountant, Willem is also a tax specialist, so he knows how to optimize everything perfectly.

Michael van Deursen,
Solid Bridge BV

In case you’re looking for an accountant who is quick, thorough and precise in his responses, Willem (or company name) is the go-to person. He can answer about any question you can come up with, knows his stuff and will explain all the options patiently including the consequences. This allows you to remain in control as a business owner.  You can feel confident bringing your financial and fiscal affairs to Willem, while focusing on the success of your business.

Rianne Grote,
Grote impact - verandermanagement

I can't recommend Willem enough as an accountant! He has provided me with excellent assistance in converting my "eenmanszaak" to a "BV". His availability for questions is really good - always ready to help and advise, which provides a reassuring feeling in the often complex world of taxes and accounting.

What truly sets Willem apart is his ability to explain everything in a clear and understandable manner. He takes the time to ensure that I fully understand what's happening and why, allowing me to confidently navigate my business. 

I can say with complete confidence that Willem is the person to whom I fully entrust my accounting. If you're looking for an experienced, reliable, and dedicated accountant, then Willem is the best choice you can make.

Suijkerbuijk + Co completely takes care of our financial administration and filing all our tax returns. We are very pleased

Ruth de Heer,
Verboom - The Mental Move B.V.

As a creative entrepreneur in design and web3, I am absolutely a massive fan of Willem. He brings peace and clarity on everything involved taxes and investments - on both personal and business matters. Willem takes on challenges (like crypto bookkeeping) where others just showed us the door. He helped us setting up our BV’s, covers payroll and monthly/yearly taxes and helps with anything simple or difficult related finance, all to a very fair price. He is that warm, friendly, calm and easy approachable expert you need when you panic about confusing letters from the tax office.The best guy you can trust with your finances as a small-sized creative business owner.

Max van Gorkum,
Make ‘em Say B.V.

Between 3 businesses and a hectic private life, Willem has been (and still is!) great to work with. He’s flexible and always comes with helpful solutions. He’s willing to explain everything in detail, no question is too crazy and always happy to help.  Besides that he’s also a great person to work with. Thank you Willem!
