We sell in GBP, EUR, and USD. Would all invoices/credit notes be converted to one currency and revenue recognized in a single currency?
Is there the ability to view the revenue recognition by currency?
If you are operating in multiple currencies, then Chargebee will display the details in the base currency and the currency in which the invoice was processed.
You can read more on how Chargebee recognizes multi-currency revenue in this document. There are examples in the document as well.
