I understand the importance of pinning print checks in QuickBooks Online (QBO), choikelly. I can share some insight about this.
In QBO, you can customize your menu and bookmark pages so it's easier to access the features you frequently use. However, the option to pin print checks is unavailable in QBO. I know how the feature can help save you time in navigating QuickBooks.
With this, I'd recommend sending a feature request directly to our Product Development team. This helps us improve your experience and the features of the program.
Here's how:
Go to the Gear menu and then select Feedback.
Type in your feature request in the description box.
