At least in Poland purchase invoice in some cases can not be included in
VAT report or must be reported in later month. (field taxDate in
invoice would be enough)
VAT tax report in Poland must be grouped by region of sale and type of sale
by so called "registry" (seller/buyer * Poland/EU/World). This is enough 
from curernt data.
However some people use more specific grouping (e.g. products/fixed assets)
If it is more common it would be nice to include it too.

In Poland is the same. In product details page it is usually shown also 
netto amount (without tax)
as separate price for company users to instant know the price.
