We're unable to match a home currency bill payment to a foreign currency transaction in QuickBooks Online (QBO), uniproUK.

In QBO, we can generate bills using different foreign currencies. However, when recording payments received or made, we can only use a bank account that matches the currency of the bill.

To work around situations where a customer or supplier pays you in a different foreign currency, you’ll need to use a temporary (dummy) bank account. Before that, ensure that the Multicurrency feature is enabled.

Here's how to set up a dummy account:

1. Go to the Gear icon, then select Chart of Accounts
2. Select New.
3. For Account type, choose Cash at bank in hand.
4. For Detail type, select Cash on hand.
5. Name it Dummy Bank.
6. Make sure the currency is set to your home currency (GBP in this example).
7. Click Save.

Once you have created the dummy account, you can record the bill payment and use the dummy bank account to post the amount. After that, transfer the funds from your dummy account to your actual bank account.

If you have any further questions about managing your currencies, feel free to reach out. I would be happy to assist you, uniproUK.
