You can see the entire life of the project KPIs, or monthly or quarterly- but we currently don't have a way to through our reports to view the totals for a single year.
​
However, you can use our "Project Period" report, choose an entire year, and then export it to CSV to add up all the quarters.

When opening your csv, be sure to indicate the delimiter of "," so that the information will be in separate cells. ( Visit this site for more info.)
