Thanks for reaching out to the Community, jetadmin. I appreciate your detailed information.
If you're interested in submitting a listing for our QuickBooks App Store, you can create a developer account on the Intuit Developer portal. This enables you to build and test apps. After you've finished creating an app, you'll be able to submit it for review.
Please don't hesitate to send a reply if there's any additional questions. Have a great Monday!
