I accidentally uninstalled app on my phone have now lost all history of invoices what do to reinstate the history?

Thanks for checking with us, ontrackhomeclean.

If you're referring to the invoices that are manually deleted, the option to reinstate the history is unavailable. We need to recreate the transactions.

However, if you're referring to the saved invoices, these transactions will not be deleted even if you've uninstalled the app. We can reinstall the application or access the account via the web browser on your phone and view the invoices from there.
 

I'll be sharing with you this article: QuickBooks Online app overview. We can find details on what information we can find in the mobile application as well as the recommended operating system.

You can always get back to me if you have any follow-up concerns about invoices, ontrackhomeclean. I'll be delighted to help you as long as I can. Have a great rest of your day!
