Task Summary is a report about hours spent on particular task by a particular team member. All data is grouped by tasks. Just go to Reporting -> Time-tracking Reports -> Task Summary to start customizing your own report.
Here you can filter information by date range, projects, team members, hours type and tasks.
For instance if you’re interested to see who worked on the task “Flyer design” in the past month, you pick “Flyer design” from the “Tasks” drop-down list, select the first and last day of the month, click on the green “Update” button and that’s it.
Note: if you choose some projects, the “Tasks list” will only have the tasks which are related to those projects.
You can print this report or even export (to Excel or CSV) with a simple click on the related button.
