Hello @rmdickey14,
As of the moment, there isn't an option to integrate your app within QuickBooks. You'll have to contact the Technical Support of your app for the assistance on how they can integrate their app to QuickBooks.
Lastly, here a few articles you can read for ideas on how you can manage your account and transactions: Help Articles for QuickBooks Online.
If there's anything else that I can help you with, let me know in the comments. I'll be here to lend a helping hand.
