we have shop where european company can checkout without tax if they have valid tax-number.
Problem is, that prices are shown without tax if a cutomer is logged in and has valid vat number. But we have added information "prices incl. tax". So this is wrong if customer has valid vat.
How can I disable showing prices in catalogue without tax. Or can I detect if customer has entered valid vat number so I can switch text "prices incl. tax -> prices excl. tax".
Thanks for help! Martin
