You can add a single company to your Risk Tracker directly from a company's Credit Report.
To do this, start by searching for the company you wish to follow via the company search and open the report for that company. In the Credit Report you will notice that there is a follow button in the top right hand corner.
Clicking the follow button will prompt you to choose a Risk Tracker Portfolio to add this company too. Once the company has been added to the portfolio you will begin to receive Risk Tacker alerts on this business as per your chosen notifications for this portfolio.
If you would like to add multiple businesses to a Risk Tracker portfolio please see this article for a quick and easy upload tool guide.
