Invoice Issued with Price List Items in Currency

Set up a pricing exchange rate (Tools > Codebooks > Pricing Exchange Rates) — this rate will be used to convert price list items.

In the issued invoice (FAV), enter the currency first, then add the price list items.

The invoice header then uses the exchange rate from the CNB (Czech National Bank) — depending on the company settings, this can be daily or monthly (this is required for accounting purposes). Alternatively, you can enter the price in the given currency as a fixed value directly in the individual price list items under the Sales Prices tab.
