I cannot link my mobile app to the online website i have on my laptop. This has all of my data already. Is anyone able to help please?

Hi there, @nbruce68. Glad to have you here in the Community.

I'm happy to help you get signed into the QuickBooks Mobile App. The app uses the same sign-in information as the web-based version, so you'll want to use that information when signing into it. If you don't remember your password, you can request a password reset to get you signed in. 

I'm including this awesome video from our YouTube channel to provide you with some information on getting started in the Mobile App. Check it out:

Please touch base with us here if there's anything else you need, I'm determined to ensure your success. Have a great weekend!
