Hello, neumann-anna-mar.
I'm unable to tell if QuickBooks can be integrated with Wix. I would recommend checking on the Wix's page if they have the option to be integrated with QuickBooks.
You can also take a look at our Apps tab and check to see if Wix is available. You can do this by clicking the Apps tab. Then, enter Wix in the Search for an app field.
I'm just here if you still need my help!
