Hello there, @lmloizou.

Allow me to provide insights regarding pulling up a report that contains the accepted estimate value and invoiced amount to date in QuickBooks Online.

At this time, being able to generate a report that contains information for the accepted estimate value and invoiced amount to date isn't available.  

To get your work done, you can run the Estimates by Customer and Sales by Customer Detail report separately, then export it to Excel. This way, you'll be able to customize the report based on the data that you need.

You may check out this link to guide you in exporting the reports to Excel: Learn how to export your reports to Microsoft Excel from QuickBooks Online.

I'm also adding this reference that provides information about the different types of reports that are available on your QuickBooks Online subscription: Learn which reports are available for your version of QuickBooks Online.

Lastly, know that our developers are constantly considering new features to be added in the system and make the product work the way your business needs. That said, I encourage you to visit our QuickBooks Online Blog site regularly, to stay in the loop with our latest updates.

Let me know if there's anything else that I can assist you with. I'll be around to address them for you. Take care!
