Hello @Sajeel,

You can pull up your Estimate by Customer report to see the list of our estimates and its status. But you'll have to open each line items to check the product or service used and its details.

Lastly, here's a few articles you can read for ideas in managing your reports and transactions: Reports and Accounting for QuickBooks Online.

If there's anything else that I can help you with, please let me know in the comments below. I'll be happy to lend a hand.
