We value your feedback and understand that you're upset about still not having this option, AR08. Allow me to elaborate on things for you so you can get back to working order.

The "Due" column is part of the Progress Invoicing feature in the Estimate form. Although you see this column on the screen when you send out an Invoice, your customer will not see that. You can click Print or Preview at the bottom to see it.

If you don't need this column, we can turn off the Progress Invoicing feature from the settings. Go to the Gear icon, click Account and Settings, then select Sales. See the screenshot below for a visual process to turn it off.

Please know that this only applies to the following invoice and won't apply to the existing ones. That said, when you convert an estimate again to an invoice, you won't be able to see the due column anymore. 

While the option to remove the Due column for the existing ones is unavailable, I recommend sending feedback to our product developers about this idea. They can further review which part of the program needs enhancements and consider adding them to future updates. 

Please understand that not all feedback requests are accepted which is why we can't provide a specific timeframe as to when this will roll out. However, our Development team will review each request, check which part of the program needs enhancements, and consider adding them to future updates.

Moreover, I'm adding this article to learn how to personalize and add specific info to your sales forms: Customize invoices, estimates, and sales receipts in QuickBooks Online.

We appreciate your patience on this. Don't hesitate to leave a reply if you have further questions. We'd be glad to assist. Keep safe always.
