As a company our invoices require a custom column so that to cover fully the details our clients and regulatory bodies needs to see in our invoices

Good day, @userinfo.jeferenterp.

Thanks for reaching out to the Community. I'm here to share information about managing invoices in QuickBooks Online (QBO).

The option to create additional columns on invoices is unavailable in QBO.

I can see how this option would be helpful for you and your business. I suggest sending feedback to our product developers. That way, they can review your request and most likely include it in our future updates. Here's how:

1. Select the Gear icon at the top, then click Feedback.
2. Enter your comments or product suggestions and select Next to submit feedback.

Moreover, you can create a new template to personalise and add specific info to your sales forms. This feature will help customise the appearance and layout of your invoices. That way, you can enhance your business' communications.

I also recommend visiting our website for tips and other resources: QBO self-help articles.

If you have more questions about invoices or anything else QuickBooks, please let me know in the comments. I'll be here to answer them. Keep safe.

You need to have an additional app with the unit measurements feature. Otherwise, consider switching to QB Desktop Premier edition.
