To view the total value of past contributions by the payroll date, select ‘Contributions’ from the main left menu. On the bottom half of this page, you will be able to view ‘History’. You will then be able to click into specific payroll dates to see the employee contribution breakdown.
If you are instead looking for a total history of contributions broken down by employees across multiple pay dates, you can run a customized report under the ‘Reports’ tab from the main left menu. Under the ‘Contributions’ report you will be able to enter the desired date range, select which fields to include, and then download a custom CSV or XLS file to your computer to view details.
