different invoice b2b and b2c

[2cool]

How can I configure the invoice to make it nice for b2b and b2c.

I want the single product price ex vat for b2b and incl vat for b2c customers.

For B2C: quantity | SKU | Name | Price with vat | Subtotal with vat
For B2B: quantity | SKU | Name | Price ex vat | Subtotal ex vat

For B2C no vat needs to be published seperately.
For B2B vat will be applied per bill at bottom.

I already have different shopper groups and price display for b2b and b2c customers in frontend.
Could anyone tell me where this is explained for VirtueMart 3.2

Thanks and regards,
Pas
