How many times have you used a software that has this. Even for international use it is amazing, plus it syncs with the best apps and plugins out there.
Ecwid was recommended to me by a friend and it was the best decision I ever made in terms of an eCommerce solution.
Easy to do business with the platform, just make sure your configurations are correct and you will be good to go.
Additionally, sometimes the CSR you get via online chat (which IS convenient, I must say) doesn't have a legitimate knowledge of all aspects of Ecwid, so it's a bit hit and miss in that sense.
You can only connect an online store and no other platforms.
The only negative I might say about Ecwid is that there can be some restrictions when trying to integrate your sales channels into Facebook and Instagram.
