I'm based in the UK, selling worldwide (with some exceptions https://paddle.com/support/countries-supported/).
Even before Brexit, if you wanted to sell digital goods to EU countries, you had to charge each country different VAT rates, register for VAT collection etc. Other countries have their own tax rules and other obligations too. Paddle lets me ignore all the admin for this which is awesome.
Does anyone know what you would do if you sold a product worldwide for a year while ignoring all this? Would you be in a real mess?
