How to record multicurrency money transfer?

Hello there, @mr_kerad. I'm here to provide details on transferring different currencies between two bank accounts in QuickBooks Online (QBO). 

In a multi-currency company, the transactions you create or enter will still be in your home currency. We use this information to track businesses in obtaining the most accurate data for their financial reports during the fiscal year.

Firstly, you can create a GBP and EUR bank account: 

1. Click the Gear icon, then go to Bank Deposit.
2. Select + Add new to add a new bank account.
3. Choose the currency, then Save and Close.

After creating a new bank account, proceed to create a bank deposit.

1. Select the GBP bank account.
2. Select the GBP currency.
3. Input the amount, then choose an account.
4. Click Save and Close.

Then, you can transfer funds from a GBP bank account to an EUR bank account. See this:

Lastly, you can now send a cheque to your customer. Here's how:

1. Select your payee.
2. Use the Euro bank account.
3. Choose the amount.
4. Select Save and close.
