Hi, @markk298 !
Glad to hear you're looking to get started selling internationally.
First and foremost, you'll want to ensure that your suppliers ship to all of the countries that you'd like to sell to. If you're using Oberlo to source your products, you can learn more about how to contact your suppliers here.
From there, you'll want to set up some international shipping rates. You can set up a broad international shipping rate that covers every country outside of your domestic zone but I'd definitely recommend hand picking countries to start and then building from there. To do international shipping properly, you’ll want to build a strategy that works for you and your business. You don’t need to know everything about shipping, but you do need to understand the available options, and find an approach that will work again and again. I'd recommend following this international shipping guide to walk you through the process of building out a strategy.
All the best!
