Thank you for your feedback! We’re thinking about supporting multiple currencies, but for the time being, you can only invoice your customers in your own currency. However, they can then pay PayPal in their own currency, so you can have customers outside your own country.Aristos Constantinou commented
As regards to your comment above, I would suggest that it would be a great idea if you can offer us the opportunity to pay in other currencies as well. I recommend that you do this as soon as possible.
