Endicia has told me now that I must charge VAT for sales into the EU and sign up for something called an IOSS number.
If Tindie isn’t going to do something to make this automatic, then I am likely going to have to stop doing business in the EU.
With the problems I had shipping to Germany, I was able to block that by excluding Germany from the “everywhere else” category. Excluding the EU means individually picking each relevant country (and I don’t know what that list is).
It’s getting to the point where I’m tempted to just limit shipping to the US and Canada and be done with it.
