Yeah, it only took 4 years for them to fix an obvious screw up. Only 4 years. Surely every business can survive that.

I don't think any EU One-stop-shop scheme covers "local" goods sales in other EU member states yet, i.e. an EU company has to register in all EU countries they hold stock in.

That is changing with the Single VAT Registration (SVR) legislation, effective in 2028.

This was 2017-2021. Not sure if One-Stop-Shop covers this as it mentions "cross-border sales" and the problem with Amazon fulfillment and storage was to make all sales local (not cross-border). But maybe it does cover it. I don't know.
