Thanks for sharing what you'd like to achieve, Ivona.
Let me share some details about receiving payments with a different currency. In QuickBooks Online, we're unable to receive the amount paid from a GBP bank account for the invoice in Euro. When receiving the payment, you'll have to ensure that the account is also in Euro to avoid any error.
In case you'd like to change the currency of your customer, I suggest following the steps below.
To start, you'll have to make the customer's profile inactive to update the customer's currency.
Here's how:
- Go to the Sales tab and then select Customers.
- Double click the customer's name and then click the Edit button.
- Select Make Inactive, then click Done.
Once done, let's recreate the profile.
- Go back to the Customers section and then click New Customer.
- Re-create the customer's profile.
- Select the Payment and billing icon.
- Click the In this customer pays me with drop-down menu, then pick GBP.
- After that, click on Save.
