How do I enter a supplier invoice with two different VAT rates?

Hi there, @csugrue. I'm here to help you enter the supplier invoice with different VAT rates in QuickBooks Online.

You can enter the two VAT rates in one invoice by adding them to the second line of your Product and Service. From there, you can enter the other VAT rates.

Here's how:

1. Select + New, then click Invoice.
2. From the Customer ▼ dropdown, select a customer. 
3. Under Product/Service, select all items and enter the VAT code in the VAT column.
4. Once done, click on Save and close.

For more details, see this article: Create invoices in QuickBooks Online.

Also, I'll be adding these links that will guide you in recording the payments and record them in QuickBooks:

Keep me posted if you have further concerns in QBO. I'll be on the lookout for your response. Have a good one.
