Can I add columns to the invoices screen? Where would I find the answer to this?

Thank you for getting in touch with the Community, Alex.

Currently, QuickBooks Online (QBO) doesn't have a feature that allows you to add columns to the invoice templates. Alternatively, you can use the custom fields features. This workaround lets you add notes or enter memos on invoices.

Moreover, it's worth noting that our Product Development Team is working to improve your QBO software. I recommend submitting a request to add this feature in the future update.

To submit a feedback online, please follow the instructions below:

1. Sign in to your QuickBooks Online company.
2. Click the Gear icon located in the upper-right-hand corner.
3. Select Feedback under PROFILE.
4. Enter your comments and product suggestions.
5. Once done, click Next to submit.

You can also track feature requests through the QuickBooks Online Feature Requests website.
