How do I make a business account (Apple ID) in Belgium?

AppleIDs are personal login IDs for Apple services. So unless you break the company name into a first and last name, no it won’t work. For businesses, Apple offers server based managed deployment options - Business - Apple

The same way you make any AppleID. There is no distinction whether you use an AppleID with a business device or a personal device.

Thanks a lot, I found this online but I don't really know what it is. https://business.apple.com/#enrollment

That link is for a bulk buy business account for a business managed deployment program (an MDM). Someone in the company with signing and purchase authority enrolls and they purchase bulk lisences for apps and content, that the MDM can then be used to push those Apps out to all the company managed devices (or whatever subset the MDM admin sets).

The bulk purchase option allows a company to buy Apps for their employees instead of having their employees use personal AppleIDs on company devices.

Apple has a special program for businesses. See the link below for more information.
