Can I have more than one bank account with a different currency associated with my Zoho Books account?

Yes, you can.

You can add as many bank accounts as you wish. Follow the steps as mentioned here to add a bank account with currency, say USD.

Once you’ve added your first bank account, follow the same steps and add another bank account which has another currency say, EUR.

You will now be able to fetch your bank feeds, create and match transactions with these accounts.
