Hello,
same problem here.
In parts of EU it is law that all B2C prices must be offered incl. tax.
I've played with the demo.
In settings > taxes you can select "inclusive" and "exclusive".
But when generating an new invoice the setting take no effect. Yes, the checkbox "Tax" aside the item is active.
Sub Total: € 10,00
Testtax (19%) € 1,90
€ 11,90
.. in both cases.
But when "inclusive" is active then it should be ..
Sub Total: € 10,00
Tax (19%) € 1,60
€ 10,00
Can you solve this soon?
