thanks for your input. I’ll set up an additional A/R for each foreign currency then.
As I usually do not use different prices for customers from different countries and only need to make sure the original price (local currency) is transferred correctly to the foreign currency I guess I can spare the extra foreign currency Selling pricelist for now.
Somehow there seem a sort of built-in exchange rate (I wonder where that comes from and whether it changes or is fixed?). As we are calculating with a fixed fee which we manually adjust from time to time (every 3 month). I figured out that once you add an entry in the “Currency Exchange List” this rate becomes the new default rate.
