Hey,

As I am trying to analyse 2023 I am noticing that historical reports from 2023 use the 2024 duty scheme instead of the actual paid duty… which makes the totals unrealistic.

Is there any way to change this?

Hi Gijs - ah yes, thanks for raising this with us! This will be because Dutch excise calculations switched from being manually managed to Breww-managed, which are two different systems behind the scenes.

We’ll take a look at this for you and see what we can do!
