MCA Suite users can record an investor's capital contributions by browsing to the 'Investor Contributions' tab of any company page. 

On that page, you can enter the date the contribution was made and the amount that was contributed. You can also enter an optional description. Once the contributions have been entered, any investor user who is associated with this company will see the total contributions on the deals page of their investor portal. 

Note that the even though the total contribution amount above is $30,000, only $5,000 has been invested in a deal. 

This feature is useful for keeping a historical record of money contributed by your investors and it will help in analyzing overall performance of your investors portfolio.
