Hi there, JMRJ.

Welcome to the QuickBooks Community. I understand that there are certain things that you need while using QuickBooks Online. Also, I recognize the importance of adding payment terms to the estimate. I'll ensure you can send feedback so your suggestion is forwarded to the Product Development Team.

I suggest going to the Gear icon in QuickBooks Online and choosing Feedback. From there, you can submit a request about having the option to add payment terms to the estimate. Any recommendations are sent to our engineer for consideration in future updates.

Lastly, you may refer to this article to see various details on how the Sales page provides you with detailed information about your sales transactions that have been created: View sales transactions.

I'll be around to help if you have any other questions related to QuickBooks. Just let me know by leaving a comment below, JMRJ. Have a nice day ahead!
