If you are using OXID for a B2B shop, you may want to show the prices in net-values (pre-VAT) on article-detail pages, product lists and in shopping-cart.
We are happy to release a module to the community today which will show net-prices throughout the shop.

It needs a lot of improvement (listed on the welcome-page), so if anyone is interested, please feel free to join the project.
If you do use this module, we would be happy to recieve your feedback!
Regards
Ashant
