Hello there, @ThumbelinaPM.

Yes, you're correct that you can record it as an expense transaction with zero VAT. You can show the parking ticket as a Travel expense because it is associated with business travel that is a subset of travel expenses.

Here's how:

1. Click + New and then select Expense.
2. Enter Payee, payment account, date, payment method.
3. Under Category details, select Travel Expense, and then enter the £30 amount.
4. Click Save and close.

For reference, you can check this article for more details: Enter and manage expenses in QuickBooks Online.

Also, you'll want to see how much you're paying and earning each month, run reports in QuickBooks Online.
