How do I add a column on the journal entry form for service codes

Hi there, @galdape.

The option to add a column in the Journal Entry page is unavailable. It would be a great feature to have inside QuickBooks Online (QBO), and we recommend sending a request to our Product Development Team. This way, they can review your suggestion and consider adding it in future updates. Here's how:

1. Access your QuickBooks Online company.
2. On the top right-corner, click the Gear icon.
3. Select Feedback and then enter your comments or product suggestions.
4. Once ready, click Next to submit feedback.

Moreover, here's an article to help you manage journal entries inside the QBO: Reverse or delete a journal entry in QuickBooks Online.

You can always count on us to reply if you need further details or assistance accomplishing QuickBooks-related tasks inside the program.
