@cartemtune thanks folks! So Australia, New Zealand, and Japan seem to be the countries that I need to take a look at. I actually can easily unblock these countries on my store and set up custom tax rates on my store so I can at least collect the taxes, but I definitely need to do more research on how to remit them correctly. maybe after that then I'll start thinking about moving to an MOR if I need to. I'm just already so cozy here lol migrating platforms is so much work :')
