About Portbase

We operate as both an IT company and a logistics service provider. We are both, and that makes us strong. We understand the market, the players, and their interests. We bring parties together, initiate chain agreements, and collaborate on solutions that make the Dutch ports and their supply chains more interesting for companies looking to transport goods across Europe.

We carefully listen to all parties in the logistics chain. From shipping company to terminal, from driver to customs officer: each link in the chain has its own challenges. Therefore, we work for the entire port community. We help them operate more efficiently and effectively by simply processing 140 million transactions per year on time through 40 different services.

Keeping things moving

Portbase has existed for 21 years now, and we are proud of that. What started as a mandate to digitize paperwork has grown into one of the most progressive Port Community Systems in the world and a connecting factor between all port partners.

In the future, we will continue to take the lead in developing comprehensive digital solutions to make integrated services simpler and more secure. If there's one thing we've learned in the past 21 years, it's that we can't stand still. As a port community, we are in motion, literally.

With this vacancy, we are actively seeking our own new colleague. If we can't find the right fit, we will take the step towards an agency to assist us. Therefore, we do not appreciate acquisition.
