ok people. The first tranch of this is in staging ready to test. I’ve included some notes above about how I’ve done the set-up and recommend someone goes through and sets up UK staging how you want it.
It looks to me like the different tax rates will be no problem, you just set two and the producer / hub selects which one applies when setting up the product
The issue about the mark-up I think we probably getting around by creating another fee type called ‘mark-up’ or by doing 2nd dot point here
