The short answer
It runs anywhere on web, iPhone and Android, but it is built for US shops: amounts show with a plain dollar sign in US formatting, there is one configurable tax rate, and customer-facing pages are English only.
A shop in Canada can use it today if a single combined tax rate and English customer pages are acceptable. Card payments go through your own Stripe or Square account, so their country support is what applies.
There is no currency switch and no second language yet. If your customers need a French or Spanish quote page, or you invoice in a currency that is not dollars, tell us; it moves up the list when a real shop asks.
