Hi @clari,
Installing QuickBooks on your iPad isn't possible. Instead of the traditional software, there is a QuickBooks app that you can connect and access through your iPad.
Please see this article for more information about QuickBooks App for Windows and Mac. I've also added this handy article for your reference: Clean install QuickBooks Desktop.
Stay in touch if you have other questions or concerns. I'd be glad to help. Thanks for visiting us today and happy weekend.
