Deal Rotting feature will help you keep track of the deals that stay in the same stage for too long.
When a deal stays in a stage longer than the rotting time, it becomes rotten. This means that it's high time to take some action and to make it move it to the next stage.
How to enable Deal Rotting?
Open the Deals page and select the needed pipeline from the drop-down.
Click the Settings button.
Switch ON the toggle next to Rotting in days and set the needed number of days. This option is set up separately for each stage.
