I'd like to begin with welcoming you to the Community, ijcbhgn.
I'd like to share some information about check scanners for QuickBooks Online.
At this time, QuickBooks Online doesn't provide check scanners. However, there's a various third-party application that you can check out that integrates with QuickBooks when scanning checks. You can do this by visiting our App page on your QuickBooks Online account.
Log in to your QuickBooks Online account.
From the left pane, click on Apps.
Search for apps in the search box.
QuickBooks displays the list of applications available that matches the description you entered. Once you find the right app, click on it to open. You can also visit this link for a better view: https://apps.intuit.com/.
From there, you can find different apps that are compatible and designed to work with QuickBooks depending on your business needs.
Lastly, I'd encourage you to visit our QuickBooks Online Blog regularly, to be updated with our latest news and updates including product improvements.
This information should get you going.
Please know that I got you covered should you need assistance with any QuickBooks concern. I'll be around to lend a helping hand. Have a great weekend!
