b2b store B2B store

[venty]

Hello,

we want to make a B2B store, the standard package has a similar mode, but we are not aware of how it works ...
Has anyone used it and can he tell us where to read about this B2B mode?
Can someone recommend a module to perform all wholesale features in different countries?
For example, the country from which the trader is charged VAT and the other countries is not accounted for ...
in Bulgaria there are, for example, transactions with 0 VAT and those that are not charged or charged at any other value ???
I suppose it is important what is visible on the screen to be reflected in the invoice ... It is also important, and by registering to reflect the type of customer ...
And are there such modules in which to trade both retail and wholesale?

Thanks in advance!
