Discover on this website how we keep our promise. Day after day. And then challenge us yourself. During your daily project work with us, you will immediately experience how our experts grow together with your experts. Together, we become a team that resolutely pursues a common goal. And achieves it. Personal contact with you is important to us on this journey.

Our all-round, hassle-free service: we are at your side. Always.

You may encounter hurdles on the way to achieving our common goal. For instance, you may need items that you cannot order via your sourcing platform, or customs may cause a problem, or the international shipping of racks may be a challenge. This is when we take over – releasing the brakes and getting the task done. In short: We are at your side. Always. We promise!

Case 3: racks in motion

We’ve delivered five large racks to you, which now urgently need to reach your office in China. Actually, they should be beamed there – that’s how much time is of the essence! But you’ve never arranged a shipment like this before, and your colleague is on holiday. How do you pack the racks safely? What do the customs requirements mean? How can this shipment now be sent out as quickly as possible? 

We dispatch such giants all the time. You’ll receive a quote from us in no time at all, and we’ll get started ASAP – with our knowledge of everything that needs to be taken into account. Including the freight documents. The information soon arrives from China:
„ 完美,一切安全到达!“
(“Perfect, everything’s arrived safely!”)
