I'm from Estonia, the usual problem when it came to industrial goods was that consumers don't have a VAT ID and are protected by Consumer Protection and Technical Regulatory Authority. In B2B, companies need to handle problems between themselves, so that means the need to offer 2 years of warranty per EU laws to consumers, labeling and instruction manual in Estonian and probably much more that I can't remember.

But given these times, it's not a problem: I already know of at least 2 wholesale food suppliers who opened up their ordering systems to be used for B2C.
