Looking to go global? You can create billing pages for each currency you want to offer, even offering different prices to different regions. Below are the steps to support multiple currencies.
You should create a Service for every currency you are planning to sell. That means creating products just like your standard offering, but adding a different metadata tag for sb_service. It's easiest to simply hyphenate the product names and sb_service name with the currency abbreviation. Go here for in depth steps of setting up pricing.
Set the currency and price to the new amount and save.
Now you just need to create a new billing page and set the Service to the newly created service. Embedding will be the same process and you will see the new currency on the billing pages.
