Trend-callout... cross-border taxation across national and state boundaries for individuals/small businesses is going to get bigger and bigger. And more and more annoying to deal with at double that rate.
I think the big companies are fine. They have the operational scale to deal with compliance. For small scale, it's much more annoying. I was looking for ways to turn off European sales on Teachable. Fortunately, they've begun offering VAT compliance as part of their payments.
