Report Fees Billed by Task Code for Client - Group Client

QUESTION: We are looking for a report that will report fee billings by task code. Is there a way to do this? If there is, can we also filter by Parent client and task code?

RESPONSE: We have looked for a report that would group by task code and found that "The Detailed Entry Report" (accessed via Reports - Work in Progress menus) is the only report that considers the task code as a reporting group. Although this report can be executed based on related object transaction date – for example the invoice date if you select billed time, for a client (not a grouped client), summarized by task code. The valued reported is the value worked which may or may not equal the value billed.

We prepared some screenshots using our database with a detailed and summarized output. 

The client and matter dashboard offers a summary of hours worked by member by task in version 2.0, however only if the matter is selected, so it would be for a different use case.
