Hi there,

Yes, there is a setting in QuickBooks Online that allows you to enable the VAT summary. I'll show the steps:

Here's how:

1. Go to the Gear icon.
2. Select Custom Form Styles.
3. Choose the template you use for your invoice.
4. Hit the Content tab.
5. You'll see a sample invoice on the right side. Tap the bottom part or the Footer.
6. Under the Display section, ensure the VAT summary is selected.
   
   
7. Click Done.

More information about this process can be found in this article: Customise invoices, estimates, and sales receipts in QuickBooks Online. Although the VAT summary option displays the VAT rate and its Net amount, the details for the VAT exemption are not included in this summary. 

But we appreciate your suggestion and recognize the importance of including this additional information when personalizing an invoice. As a result, I recommend sending feedback to our Product Development team so that it can be considered in the next update. Like this:

1. Go to the Gear icon at the top.
2. Select Feedback.
3. Enter your comments or product suggestions. Then click Next to submit.

Let me know if you have any further questions about VAT or other invoice-related issues. I'll be here to assist you.
