Hi,
Ah ok, I didn't understand that each tax rate applied to a different proportion of the price of the product.
Still, the bundle feature won't help you. For now, the bundle feature doesn't use the prices of the sub products, only the price of the main product.
Instead, you can use options.
You need to:
- create a product which will be the main product with the price being low VAT part of the total price. In it, select a tax category for the low VAT rate.
- create a product with a characteristic with one variant with a gross price for the high VAT part of the total price. In it, select a tax category for the high VAT rate. Assign that product to an unpublished category so that it doesn't appear on its own.
- add that second product to the first product as an option.
That way on the product page of the first product, you'll get a mandatory option and the total price of that product + the option product, each one with their own VAT rate. You can also add CSS tohide the option area on the product page so that it doesn't appear.
