item list in an invoice or estimate

Hey there, @inbu512!

Currently, the feature to make attachments appear on sales forms is unavailable. I understand the benefit of providing your customers with more details about your product. 

For now, you can send feedback to our development team so they can review and consider your suggestion for future product enhancements.

Here's how:

1. Click on the Gear icon and select Feedback.
2. Enter your comments or product suggestions.
3. Hit Next to submit.

Also, you can check out this helpful article to learn how to personalize your sales forms: Customize invoices, estimates, and sales receipts in QuickBooks Online.

Please feel free to reach out if you have any follow-up concerns. I'm here to help. Have a great day ahead!
