Is there a simple way to update the Markup on all items at one time rather than going to each one individually?

Hi there, harringtoninc.

Being able to update the Markup on all items all at once is not yet available. I'd love to share this suggestion to our engineers for consideration in future product enhancements. In the meantime, I want you to be updated with the new features added in the software, you can check the New Features option in QuickBooks Desktop.

Here's how:

1. Go to the Help icon.
2. Click New Features.
3. Choose either New Feature Tour or What's New.
   

Another way to be updated to the latest feature release in QuickBooks Desktop is through this website: QuickBooks Updates: New QuickBooks Accounting Software Updates.

You can always go back to this thread if you have other questions. It's my pleasure to help in any way I can. Have a good one.
