I appreciate you for getting back to us, Tanja.

Thanks for adding a screenshot. It gives me a visual representation of your concerns.

Currently, the option to modify the details under the Estimate summary field is unavailable in QuickBooks. It's designed this way so you'll have an overview of the estimate created.

That said, I'll take note of this suggestion and share it with our Developers page.

In the meantime, you can visit this page to know the latest and updated features in QuickBooks: Customer Feedback.

In addition, when you're ready to convert an estimate to an invoice, you can check this guide: Convert Estimate to an Invoice.

Keep me posted, Tanja. I'll be around to help you out!
