Exchange rate adjustment

The problem

You invoice in one currency and collect in another. The amount received doesn't exactly match the invoice due to exchange rate fluctuations. The invoice says €1,000 but you received €980. The €20 difference needs correct tax treatment.

How to resolve it

In the tax document panel, when the collected amount doesn't match the invoice, a button appears: Adjust exchange rate difference (XX €). One click creates:

• A compensation transaction (income) that covers the gap on the original invoice → marked as paid.
• A fiscal transaction (expense) for the exchange loss → with its own entry in the expense book, 0% VAT, no invoice number.

The two transactions cancel out in the account (net = €0), so the balance doesn't change. If you collected more, the roles reverse: the expense becomes income and vice versa.

Result in the books

• The original invoice shows as paid in the income book.
• The difference appears as a separate entry in the expense book (or income book if you collected more), with 0% VAT and no invoice number.
