With Billwerk+ Optimize you can sell subscription products and bill your customers in multiple currencies.  

When you create your account, you choose your primary currency. By default, all products and invoices will be created with this currency.  

When you create a new plan, addon or discount you can select the currency for this product. 


It is not possible to combine products with different currencies in one subscription nor is it possible to change a subscription to a product in a different currency.  

If you want to bill a subscription in a different currency, you can expire the subscription and create a new one.
