Thanks for attaching a screenshot. I'm here to help you customize your invoice template.
We're unable to remove the Item column on the transaction screen since this is where you select the product and services that you sell. Though you have to option to hide o remove it on the printed invoices. I'll show you how:
Select Lists from the top menu bar.
Open your existing invoice template, select New from the Template drop-down menu to create another one.
Click the Additional Customization button.
Go to the Columns tab.
From the Item section, untick the checkbox for Print. (As you can see, the checkbox for Screen is grayed out).
Hope you’re doing great. I wanted to see how everything is going about the issue in your invoice template yesterday. Was it resolved? Do you need any additional help or clarification? If you do, just let me know. I’d be happy to help you at anytime.
Looking forward to your reply. Have a pleasant day ahead!
