Why does sales so often feel uncomfortable and forced? Because we've been conditioned to convince rather than genuinely help.

This book is a practical guide for anyone who is fed up with that traditional, pushy sales approach and yearns for something that truly works: creating true fans.

Sales, Honest & Relaxed is practical and immediately applicable. A taste of what you'll take away:

Why sales so often feels uncomfortable, and how to turn that around.

About the author

For 25 years I stood on the front line as an entrepreneur and CEO. I built market research agency WUA, generating tens of millions of euros in revenue across 21 countries, with clients like Google, Samsung, Microsoft, Bol and ING. After selling the company in 2022, I train teams and professionals in honest and relaxed selling, over 1,000 by now. This book is the distillation of everything I learned in those years.

Klaas Kroezen, interview Managementboek.nl

Sales is human contact.
Genuine interest.

In an interview with Managementboek.nl, I share the core of my philosophy.

Read the full interview

“So much energy is lost in sales due to constant performance pressure. When conversations carry that weight, genuine connection disappears. And people sense it immediately.”

“Meetings become disguised transactions. Divided attention undermines trust. The other person feels they're not truly being heard.”

“Someone told me: 'You're moving too fast. You're not making real contact.' That changed everything, from transaction-focused to relationship-focused work.”

About the book.
Frequently asked questions.

A good book about sales teaches you to sell in a way that fits who you are. With Sales, Oprecht & Ontspannen (Sales, Honest & Relaxed) I wrote such a book: selling from genuine connection and relaxation, based on my 25+ years of hands-on experience. It reached number 1 at Managementboek and over 3,000 copies have been sold.

It is about why sales so often feels awkward and forced, and how it can be different. We are conditioned to persuade, while genuinely helping works far better: for your customer and for your revenue. I walk you through the mindset, attitude and beliefs that make selling relaxed, with stories, theory and plenty of customer research from my 25+ years of practice.

For anyone who is commercially active: sales professionals, entrepreneurs, account managers and managers. But also for people who 'do something with customers' and want to get better at it, simply as themselves.

Yes. The book is about genuine contact with customers, and that applies to everyone who works with clients: from consultants to entrepreneurs. Especially if selling puts you off, this book shows it can actually feel comfortable.

The English hardcover is sold through Amazon, so delivery time and shipping cost follow your local Amazon store. The e-book and the audiobook you order here directly and they are available immediately after payment, wherever you are in the world.

I narrate it myself. So you hear the stories and insights exactly as I intended them.
