Project management with JIRA

It always amazes me that (software) projects tend to go over budget. That is why I am planning to launch a product that integrates the time administration with a direct link to JIRA. This makes it possible to write the hours per story, track productivity and invoice projects based on written hours. Currently we have this application up-and-running for our own company.

What are features that you would like to see in this product?

It already can be linked to PowerBI and has some dashboard features that are useful to see the co-independence of each story and therewith make a fairly accurate prediction if the project is still on track.

Do you use software to manage your projects?
