Prices ex vat on pdf invoice

-- url of the page with the problem -- : www.ubuntushop.biz
-- HikaShop version -- : 5.1.1
-- Joomla version -- : 5.1
-- PHP version -- : 8.3

I need to add subtotal price without vat on the pdf invoice.
How can I do that. Or I am misshing some setting?

ok, but I have to show the prices in the shop with tax (or with and ex vat)
But only for the pdf invoice i need the unit prices without vat and the subtotal ex vat.
Then the total with vat (as it is now)
And for the no eu-countries there is no vat.
Like this:
unit price: 20 (is without vat)
subtotal ex vat: 20
vat: 4.2
total: 24.2
probably i need to change in plugins/hikashop/attachinvoice/attachinvoice/corporate_invoice.php
But only a subtotal without vat should be good for me.

I was able to edit in plugins/hikashop/attachinvoice/attachinvoice/corporate_invoice.php according legislation
Now i have:
unit price: 20 (is without vat)
subtotal ex vat: 20
vat: 4.2
total: 24.2
thanks for the help
