How can i proceed a currency exchange operation entry ?

Welcome to the Community, @j-koborsy.

QuickBooks Online (QBO) has a feature that will allow you to create Journal Entry (JE). You can use this to enter a currency exchange operation entry. Before doing so, I suggest consulting your accountant for further assistance with the process to ensure your books are accurate for your business.

Here's how:

1. In QBO, go to the + New icon option at the top left to get to the Journal Entry.
2. Enter the necessary information in the desired fields.
3. Hit Save and close to complete.

For more information, consider checking out this article: Mixing currencies in journal entries.

Just in case, I'll add these articles for future reference:

• Enter an exchange rate.
• Multi-currency FAQ.
