There are 2 places where you can check the ROI generated from your campaign/s in Contact Reach.
I. In your Dashboard
The Dashboard is the very 1st thing you see when you log in to the software through https://contactreach.co/app/login
You'll notice that there's a Revenue Generated section in the Dashboard. That's the total ROI accumulated from all campaigns. You'll also see how the ROI has grown from the previous week or month (depending on the interval you chose in the dashboard).
II. Campaigns List
If you're having problems with the ROI, you can reach out to support.
