In our shop we have the product prices including VAT in our database. We have multiple countries with different standard VAT rates. In the settings we checked 'Prices in the database include VAT' and 'Use VAT group rate as system VAT' and added a VAT group with the correct VAT rate per country and set the type to 'Default'.
We were hoping that all current groups and products would use this VAT group but it looks like they don't. The VAT only gets correctly calculated when we assign the VAT group to a product. Is there an option to force all current groups and products to use this VAT group? And also that newly created groups (and products) have this VAT Group set as default?
Or maybe someone knows a different approach to fix this problem?
