Hi there, @Doug Robinson.

I want to make sure you can integrate QuickBooks Online (QBO) with Zettle.

You can connect your Zettle account to QBO by just entering your QuickBooks login details. However, since you're prompt to activate your VAT, I recommend reaching out to the Zettle support team. This way, they can help bypass the option and continue connecting your Zettle account to QBO without activating the VAT.

I'm adding this article for more information: How do I connect QuickBooks with Zettle?

As always, you can visit our QuickBooks Community help website if you need tips and related articles in the future.

Please keep in touch if there's anything else I can do to help you succeed with QuickBooks. I've got your back.
