Hi Shopify Team,
Please can you look into adding Taxamo as an integration for non-Shopify plus members. How are we supposed to grow our business to afford a Shopify plus membership if there is no simple low cost option to sell internationally. I understand this implementation is not your fault but please can you see what can be done t help us with this.
Kind wishes,
Natalie

I might be slightly biased tho, but reviews support my assessment!
