Hello @billing10,
As of now, QuickBooks Online doesn't have an option to customize the columns on your Invoices Summary page.
As a workaround, you can filter your All Sales page and customize its columns. Let me guide you how.
- On your All Sales page, click the Filter drop-down.
- Under the Type section, select Invoices.
- On the page, click the Gear icon.
- From there, you can choose Columns you want to customize.
I've attached screenshot below for your reference.
Also, I encourage sending feedback to our engineering team by going to the Gear icon, then selecting Feedback. This way, they can consider checking and working on the option to customize the columns on the Invoices Summary page.
You can always get back to here in the Community if you have any other questions.
