To sell globally on Shopify, you must localize: language & currency.
Use Translate & Adapt, Weglot or Langify.
Pro tip: if you only need 2 extra languages, use Shopify’s native app – others load externally which will slow down your page speed.
Same goes for apps, by the way: the fewer, the better.
Every extra app can slow things down or break something.
Often it’s smarter to invest in a custom solution and avoid another dependency in your tech stack.
