Bloom uses Square and Stripe to process payments. Anywhere that either of these are available, Bloom is as well.
According to Square's support center; Square is currently available in the US, Canada, Australia, Japan, the United Kingdom, Republic of Ireland, France, and Spain.
We currently don’t support payment card processing outside of these countries or in U.S. territories such as Puerto Rico, Guam, the U.S. Virgin Islands, American Samoa, and the Northern Mariana Islands.
According to their website, Stripe is available in 47 countries.
