Sales training by the best sales trainer of the Netherlands 2025

OEM Office Elearning Menu trains your employees in IT, Microsoft 365 and AI. For sales skills, I run a separate training institute: Graham Hulsebos Verkooptrainingen. In 2025, I was named the best sales trainer of the Netherlands. My trainings score an average of 9.6 from more than 900 reviews.

Software makes your team faster. Sales skills make your team more successful. Who would not want both?

Sales is a science, not luck

I have worked in sales for 30 years and have trained sales professionals since 2003. More than 2,000 participants from over 400 organisations have attended my trainings. I translated that experience into one closed system: 12 sales techniques and 11 scientific topics. No loose tips, but a method that works in every industry.

Your salespeople learn to take control of every conversation, from first contact to signature. Selling is asking, not telling: whoever asks the right questions steers the conversation. Read more about my method.

Who is the sales training for?

The training is for everyone who sells in direct contact with customers: account managers, field sales, inside sales, telesales and retail staff. Sales managers and directors who want to take their team to the next level will also find their programme here. Working in a specific sector? See the sales training by industry.

English-language trainings are delivered by Kyle Campbell, native English trainer, using the same method.

Choose the format that suits you

• In-company sales training: fully tailored, at your location, for up to 12 participants.
• Dedicated sales training: only your own team, at one of my training locations, including venue and lunch.
• Classroom sales training: in small groups of up to 8 participants, at 12 locations in the Netherlands.
• Online sales training: live via Teams or Google Meet, with the same depth as on location.

AI and sales: the logical combination

Is your team already using Copilot or ChatGPT? Then the next step is using AI in the sales conversation itself: preparing, following up and quoting in a fraction of the time. You learn this in the AI Sales e-learning, available 24/7. This way, the IT trainings of OEM and my sales trainings reinforce each other.
