When an offering has reached its desired funding, admins can close the project so no further investments can be placed through the Investor Portal.
Step by Step:
From the admin dashboard, go to projects > project lists > select project > click the dropdown menu and select edit project. Then change the project status to funded and enter the closing date of the project and select save. Once you have saved > open the project > select the entity and class you want to close > select the three dots in the right hand side of page > close class.
